[Q] SD Cards. Good or Bad? - RAZR HD Q&A, Help & Troubleshooting

Hi,
I have an unlocked Razr HD with expanded external SD of 13 GB. I just use it to store media files, mainly songs, some movies. All apps are in the internal memory. Since I flash roms whenevr they arrive, I find it convenient to store my files in the external disk so that a swipe will not remove these.
A friend once told me that just having the sd card increases the load on the motherboard and decreases the performance. The performance takes a hit. Also, the life of the phone diminishes with time.
Since I have 32 GB inbuilt, I am wondering if I should ditch the external one, if its really that bad. Any suggestions?

im sure there could be some slow down, especially if you have a corrupt file on there and dont know it, but decreasing the life of the phone seems a little far fetched in my opinion.

I would like to know where your friend got his information from. It decreases the phone's lifetime? Now, if you write to an external SD card frequently, it will cause the SD card to eventually fail, but that depends on how much writing you do to it. Since you are just storing media, you should be fine.
But, an SD card will not cause the phone's lifetime to diminish.

With 4.2(?) the defragmentation feature "fstrim" was incorporated.
If rooted you can use the apk version.
Not having it is the reason new phones have worked better. Reformatting & copying files back is the only way to get defragmentation w/o fstrim.

solid state drives and similar (sd cards) never need defrag, in fact it reduces the life span i believe.
not sure what genius though that would be helpful.

How do you think it stays clean? The 2nd law of thermodynamics says not. IOS has had it long before android!

Have you ever noticed a new JB phone writing much faster than an older. Also an old 4.4 phone writing slower than a newer, there is noticeable overhead in the fstrim doing its stuff.

this contradicts most of what i have read about flash drives, but things change, and ill look into it.

It may be in JB 4.2 "AFAIK FSTRIM has been a part of Android since 4.2 though oddly google didn't enable it for the N7 at that point, perhaps Asus have flicked the switch."

this "it has the associated drawbacks of increased write amplification and wear of the flash cells" is consistent with what i have read a few years ago, as i have been using ssd's for a good 4 years or more on pc.
i wasnt aware of the "trim" feature in pc or android, but it does sound beneficial, however still seems like it will reduce life span by default.
thanks for the info though

HTC Amaze VS HTC One S

Is it really worth upgrading from the amaze to the one s??!!
Probably not unless you REALLY have to have ICS right away and the upgraded camera hardware. I'd say wait until you're upgrade eligible, unless you are now, in which case I'd probably upgrade cause I really like this phone.

When you call it an UPGRADE then yes it's worth it
It's a lot more future proof than the Amaze IMO, probably going to have a lot more development as well.
How can a such high caliber HTC One S lacks a microSD slot? Don't know about you guys but the available ~12Gb or so just AIN'T enough.

why should u bet all your music collection in your phone, when u wont listen to all of it anyway?
ATM I have 8gb sdcard, and still 1gb left + alot of music I dont even listen to. I could easy free up even more space...
Just dont take "all the ****s" with you, Change music in your phone time by time instead of taking it all with you and just "skip -> skip -> skip -> 5x skip -> ok this is nice song"
if you bought premium navigation, 16GB is not enough.

from name I understand its some kind of GPS where maps are saved on your sdcard?
If so, Im using mapdroyid which also saved maps on my sdcard, still have free space.
Im wondering, with no sd card, how will rooting and installing roms/backups and what not work now.
I mean, when you have to wipe the phone, youre gonna have to copy all that stuff on the phone to a PC and then move it back later?
Thats one of the things that made me iffy on the one s.
Storage isnt an issue... it comes with 25gb drobox space, You can take all your stuff with you..
And are you really gunna need 12gb worth of pics and music and whatever on your phone ?? As said above its easy to just swap stuff over, Load it back to dropbox and download something else. Keep it fresh
And i think its silly they dont have an SD slot, But look how thin this device is ! its soo slim, compromises had to be made..
And when you do a wipe, Unless you wipe internal SD card, (which you dont need to when doing a 'wipe') all your media will remain, Only the partition that keeps apps and data will be wiped. So again, Its no big deal..
Look at the potential this phone has, when development starts, nothing is gonna keep this bad boy down
No
azzledazzle is wright, but you can also wipe the sd partition and then mount usb storage to copy files on it (rom...gapps) from cwm recovery. I did that on Nexus S last night.

I think people are getting too much of a hard on for Krait. Yes, the S4 soc is amazing. But there are plenty of downers to this phone already.
1) HTC's amazing track record with batteries... Don't get me wrong, love HTC... but omg I've had to replace batteries on several phones after a year. Much nicer when you can just pay $20 for a chinese battery off amazon that works wonders as opposed to having to get the phone serviced.
I mean, honestly, why couldn't the phone have been build like the Sensation/Amaze and lift off that awesome aluminum back?
2) T-Mobile's coverage and the 25 GB of cloud storage - Depending on where you live, this 25gb is gonna SUCK because you can't access it worth a damn.
Though to be fare, everyone who's said "Just swap out your data" is completely right. You don't NEED 32gb of storage on your phone unless you want to be all "Hey, look at all the **** I've got." Which is something the cult of Apple has nurtured in a lot of people through iTunes.
3) Bottleneck - The parts are better than the software they run on. Honestly, this isn't a gaming PC. This isn't a PC at all. You can't just keep throwing higher and higher end parts into a phone expecting it to work better, you hit a performance plateau. Beyond benchmarks, we are starting to see android's limits at this point in standard use. I honestly feel that the HTC Sensation and Amaze are the best Gingerbread and ICS will offer in phones. Everything else is just stylish masturbation.
4) The Micro Arc Oxidation treatment has been shown to not be as durable on some phones as it should be. I've seen a couple blogs and several owners attest to this. If I can't have my HTC One S with that kickass plasma treatment and red accents without it flaking off I don't want it at all
Really guys, the Amaze (and it's lil bro the Sensation) are both great phones. If you don't mind taking the time to upgrade the sensation to a sensation xe rom you can get a very stable 1.5-1.7 ghz overclock and the Amaze battery fits in it, leaving you with one very very nice piece of machine. I got one to replace a busted Amaze and it runs very nice and I almost don't want to use my Amaze again now that it's fixed...
But back on to the One S... It's pretty, but it's really just HTC's one up of the Galaxy Nexus and Razr MAXX. Don't give in to the stylistic oneupmanship, just hold off and get the next monster they put out. I guarantee you we will see a monster of a phone in a few months that will basically be the next Amaze.
It's small and stylish. Feels great to hold in the hand as opposed to the other giants HTC has released during the years. Why all so called "flagship" models must have ridiculous screen sizes is beyond my understanding - the One S fits right in where it belongs and I think the upgrade is more on the aesthetic side than anything...
Like the above poster, I don't think that the storage space is an issue at all. (Coming previously from a Galaxy S 8gb model which I never really maxed out) and use the cloud if you need the space, hell it's even recommended why wouldn't you want your stuff sync'd all the time? I don't really see the point in having on board storage that I can't backup 24/7 anyway and with today's free data plans, most of us don't care for storing things locally.
But that's just my 2c.

What about when you're somewhere where theres no service or limited service. Viewing, transferring or downloading from dropbox will be impossible.
Or how about this senerio, starting to have to start saving our best, most intimate photos, important files to dropbox because you're already out of space in internal storage and dropbox crashes. Everything lost, forever.
No SD card slot for expandable storage is ridiculous.
For me it makes perfect sense. All my music is streamed through our Subsonic server, pictures auto update to a private G+ album, docs are on Gdocs.
If I'm going to the mountains I just preload some music and I'm good to go.
Physical storage is dying; long live the cloud

I agree wholeheartedly. I get why people don't like the cloud but I have never had any issues with cloud storage. I also use Subsonic to stream my music and it works great. The Subsonic app also caches music on my phone so if I have a bad connection I still have tunes. Also, I have no problem uploading my pictures and everything to Dropbox. Honestly, the lack of storage doesn't concern me at all.

surely you wont need 8GB+ storage for one day ?? you must have access to a computer where you can swap files and remove some stuff you wont be using ?
if the storage is such a problem for you... dont get the One S.. get something else

My device is my computer. Why would I need to be around a PC to swap files back and forth. Why go through that hassle with a mobile device? Then what would be that point of a mobile device?
Yea, you're right. I won't be going for the one s for sure. Amaze will be a better choice.
Mobile devices suppost to help by having data with you, but it cannot replace PC if u want all ur things with u then it wont be so mobile anymore, thats why ppl make cloud storage and cloud computing

Phone finally fast

Hey Guys,
I finally got my phone to work at a decent speed. Here are the things I did:
1. Used Apps2SD to move the apps from internal storage to SD Card. Wondering why this helped? As far as I understand the apps are run in RAM and internal storage is used for storing data and apks etc. RAM is freed up by Android as and when needed but freeing up internal storage doesn't give android more RAM.
2. Use Autorun Manager to prevent some apps from starting up and remaining in memory. Now this I understand because this gives more RAM to android and avoids unnecessary swapping when applications are started up.
3. Used 'SD Booster' to increase sd cache size to 8192Kb. This gave some initial benefits but later on it became very slow as usual.
Bottom line is I am still puzzled by Android memory and SD card management. I am pretty sure though process swapping in and out of memory is what caused my phone to slow down. My Samsung Droid Charge is supposed to have 512MB of RAM but most memory managers show only 374MB and 2 GB of internal storage and most tools show only 1.2GB. Why would this be? Am I missing something or should I use a different tool to analyze my memory.
Not sure about RAM but usually when u buy a hard drive the bigger the hard drive the lower the actual number of gigs. Maybe it is actually 1.2GB

1. This one must be a placebo effect because if anything moving apps to sd card will make the phone slower. Our internal memory has way higher i/o speeds (especially on ext4) than the measly class 2 sd.
2. This is usually not a good idea. The processes you "block" will actually still run but they will be insta-killed. They will keep trying to start up and will drain the battery.

Thats what I thought. Im no guru, but out of all the reading Ive done, they have all said that moving apps from the sdcard to internal speeds up things.
Im looking at ways to speed up my wife's droid charge. Shes been complaining about it and finally gave me the go on rooting and maybee ROMing. I would like to stick to stock if possible so she wont run into any problems but if I have to I will install a custom rom. Any links?
Nope this is no placebo effect. The phone has become very fast. There are several posts that say that moving the apps to sd card speeds up the phone. In fact of all the things this is what sped up my phone the most. Why else would app2sd be so popular? Read #4 on http://www.talkandroid.com/guides/b...lean-up-and-speed-up-your-android-smartphone/ .
To further speed up my phone I am trying to overclock. My phone is stable at 1.2GHz but at 1.3 GHz it reboots after some time. To make it stable at 1.3GHz should I increase the voltage at that frequency?

Read it again. That's only about getting extra app space on smaller-storage devices. They actually recommend against moving things you use frequently in your linked article.
I'm with the others. Any gains you're seeing from this are placebo. There's nothing inherently faster about external storage.

It has a total of 512MB RAM, and that is for everything, so the GPU and other such things have to take their share from the total pool. On the GB releases, that leaves us with 374MB. It's better than it used to be. On the Froyo releases, we only had 327MB to work with.

No, on a hard drive (or solid state drives or even SD/memory cards), what you buy is what you get. However, due to formatting, space reserved for backup/spare sectors, and what is considered a "gigabyte" to manufacturers vs consumers (1000 mb vs 1024 mb) you often end up with around 95% (probably off on that percentage) of the stated capacity. With RAM this is not the case, as that type of memory doesn't need formatting as its holding raw data with the computer making up its structure. And manufacturers of RAM are in agreement with consumers as to what a gig is.

This is the difference between a gigabyte and a gibibyte. Hard drives are usually advertised in gigabytes (literally 1 billion bytes), while most OSes use gibibytes (2^30 bytes, or 1,073,741,824 bytes), since they do everything in "base 2", or binary. So an advertised 10GB hard drive has 10 billion bytes. Once you format the drive, the OS reports size in gibibytes, so you end up with:
Code:
10,000,000,000 / 1,073,741,824 = ~9.31GiB
That's also why if you look on most hard drive packages, it says "formatted size may be different than advertised size" or something similar.
Just a random fact of the day. Feel free to ignore it.
On topic: I don't believe the giga/gibi (or in the case of phone RAM, mega/mebi) is the issue. 512MB converted to mebibytes is roughly 488MiB. I believe the Charge is a 512MB device with some of that memory reserved for OS/system-only purposes. I could be wrong on that, however, so if anyone could clarify that'd be great.
Edit: Could have sworn I read through all of the replies before replying myself. I guess I didn't because multiple people beat me on both points by a day. Sorry about that duplicate info.

The number one lesson I learned from buying this phone
Check the amount of run time memory before you buy a phone, especially if you have two companies like Verizon and Samsung loading bloatware. You were forced to root the phone and rid yourself of the bloatware, or not buy apps. I totally agree with the OP. He is 100% correct about the run time memory.
So I restored back to factory to get ready for another root. After the required Verizon and Samsung updates, hitting the clear memory button, I'm using 268MB of 373MB. Now I know the OS can swap, (because we love paging), but it really is ridiculous. I can't wait until March. Good luck everyone.

I couldn't understand what you are saying here. From what I understand you are saying that is that when you rooted your phone you had 512MB of memory but after you installed Verizon and Samsung updates it started saying you had 373MB. So is it that Samsung and Verizon updates are taking away about 147 MB of memory? What is going to happen in March?

No. Hardware wise the Charge has a total of 512 mb of RAM. The GPU and other hardware have to take from that pool, and the end result is that the Android OS has 373 MB of RAM to use. Verizon and Samsung bloatware and updates have no control over the hardware aspect, but the bloatware DOES utilize some ram while the phone is running (but does not take from that pool). March is probably when his upgrade is.

Ok so I can clearly see that my phone is becoming slow again. Not sure as to what it is related to. Though one thing that surprises me is that I overclocked the CPU to 1.2 GHz and set the governor as 'conservative' and sometimes even ' smartassv2' but it changes to 'ondemand' even though I never changed it to that value. Why is this happening?

Plugging the phone into a pc does that for some reason.

I have to agree that even though my phone was initially fast it slowed down considerably after some time. Frustrated I then backuped my phone using Titanium backup and installed Tweaked 2.2 Rom + PBJ. But this time I did the conversion to EXT4 and the phone has become super snappy and the fastest I have ever seen. However, I am not rejoicing right now because I have only installed some very necessary apps like navigation, yelp etc. Don't know if the phone will be come slow after I install more apps. On Seepu I can see for the first time my used memory is green and this probably is a major reason why the phone has speeded up. Another factor is the EXT4 conversion.
Infinity was known for slowing down over a short period of time. Tweaked 2.2 is quite a bit better. But running a Droid Charge for several days without rebooting it once in a while will cause it to slow down too. Just reboot when it starts slowing down. It should help.
Before I add any more apps I want to save this state of the phone so that I can go back to this if the performance degrades. What do I have to do for this? I used Titanium backup but I see that it saves app data and you have to install each individual app. What I want is to make one click and restore my phone back to the state it previously was. Should I do a nandroid backup

[Q] Sandisk 64GB Micro SD Issues

Hello all,
I have had my TF700 corrupt two Sandisk 64GB Micro SD class 10 cards beyond repair. chkdisk and reformatting are useless as the drive becomes unrecognizable in multiple computers. 32GB cards work just fine. Is anyone else having similar issues?

If these are SDXC cards, I've had a similar issue. This was resolved by using the official SD Association formatter utility. I had two cards which showed as "Bad Disk" in MiniTool Partition Wizard but by using the formatter I got both back working.

I got the program and reformatted "Full". Started to copy some files and get an error that the disk cannot be read. I close windows explorer, click on the drive letter and no disk is found. Sigh...
Thank you for your response as I will use this utility in the future.
Last piece of advice: it is NOT the TF700, but MiniTool that *****s up your memory cards. We've had lots and lots of reports, but Mistar Muffin (the OP of the data2sd thread) apparently rejects to update his opening post and recommendations on the matter.
Use Gparted instead (comes on a bootable ISO to boot, so even under Windows you won't even have to install it), and away with your problems.

Marty,
I do not use data2sd, minitool or Gparted. I do use Browser2SD. Could that be it?

I had a card corrupted by MiniTool, but Mistar Muffin has updated his OP in the data2sd thread. It now mentions to use GParted, a much better utility.
The TF700T is not known to corrupt cards. I'm using a 64GB class 10 Sandisk microsd with data2sd and no issues for months.
For a faster browser, just use Firefox, instead of doing stock browser hacks. I've just always found Firefox gives me less issues than the stock browser with or without browser2ram.

No, and you didn't say anything to make me think you did: I replied to KingFisherUK to avoid someone else picking up MiniTool and having their microSD cards crap out on them as well.
It may depend on how you formatted it. Browser2ram -- which I think you mean -- is not exactly known to throw up severe errors, and if it is not installed correctly it will just plainly not work.
Still, I'd get the gParted ISO and try to recover your dead cards. I did the same with mine, and although it took a harrowing evening -- seriously, I will not repeat it if I can help it :S -- I did get it to work again...

To each his own, apparently, for I have found Firefox sluggish. Really sluggish. Stock browser on CROMI(-X) gives much better results on the web sites I visit regularly. And I actually do notice a speed increase with browser2ram. There are way too many variables at work here, I guess, to make a blanket recommendation that will fit all.
PS: the same goes for Chrome, Dolphin, Boat, and all the other browsers I have used (and sometimes loved) in the past.
Had also the described problems. These could be resolved through Windows chkdisc (important: the check may take very long - you may actually think that chkdisc does not respond any more - just be patient and wait!).
My failure was quite interesting and I got screwed for a new card even thought the old one is under warranty as its only about 6 mos old. The card still basically works but is unreliable and semi-dysfunctional. All the usual diagnostics indicate both corrupt files and file system/bad track 0, but somehow the ro bit for the entire disk (card) /dev/sdc got hard set, but not exactly. I could create files and directories on-device, copy from the card but not to the card with a PC, and could not delete anything nor format/partition the card. Its now one-way storage. 64 GB of my life locked on a flash card. I will destroy it myself. That way I know it got done.
I tried everything including GParted, the official SDCard Formatter (Windows), DOS, Linux dd and the advanced one (forgot the name) for sensitive data used by the DOD and FBI to recover erased data. I even tried Wii, Xbox, and some manufacture of the controller chip for the cards (forgot the name). All my data is still on the card despite my best effort to destroy it; the wire for the erase/format signals must have fractured under heat or over writing and I fear not RMA it because it has personal data including complete backups, IP sensitive business documents, photos, contacts, emails, and my last 3 years tax returns not to mention a music and video library. For a buck a gig I can rest easy that the chip won't make it to a dumpster or get lost in the mail, then found and my identity stolen or hacked. Even though it probably wouldn't happen, it could and that's enough to keep me up at night. Is just not worth the risk. I just replaced it with a Patriot some size/class/speed on sale and its working fine. My case could be a statistical insignificance, but after getting burned by Sandisk, I'm questioning whether their quality has dropped after they grabbed market share and some of their competitors might be where the quality is at now? Well see how the Patriot does in comparison. It shouldn't be too hard to beat 6 mos.
Read this. They've recently upgraded their firmware due to some data corruption problems on newer devices (like TF700T?).

SD Card - MM - OG Shield Tablet

I finally was able to upgrade my tablet.
I do not want to use adoptable storage... but noticed i can no longer move apps to external SD. The ones that were moved previously, im given the option to move them back, but not vice versa. From what im reading this only seems possible now with adoptable storage?
I would just like to know if thats the case. I am on stock... but rooted MM with TWRP recovery.
Yep. It's a security feature in Android now; it is a compromise that Google made with the people who own the phones (and desire to have more storage) and the people who want to make sure that the system is secure (developers, and so on).
If you want to stay on stock those are your choices at the moment.

i understand. thanks for the quick reply.
Funny thing is, my Shield TV just updated to MM as well. I opted out of adoptable storage as well, but that still lets me put things on my SD card without issue...

That is interesting! I hadn't read anyone dealing with the MM on the Shield TV. I don't have one so I hadn't read up on it. I'd hate to think about why that is.
That being said, Samsung and LG have expandable storage on their new phones, but they won't let you adopt them as internal storage, which only confuses the matter more.
I had to format my sdcard to NTFS on lollipop and haven't had trouble with it since the upgrade to mm. I just had to make sure to set the root of the sdcard as the home folder for the file browser

Here's how to configure adoptable storage on your S7 / S7 Edge without root

Just saw the news that Modaco has released a guide on how to use ADB to enable your S7 adaptable storage! And no root required, so Samsung Pay and future Samsung update will work as intended!
Can wait to go home and try it.

Seems to have worked for me. Thanks for sharing.
For those who have done this... has your phone slowed down? What card are you using?

Might need to be using this when I get my phone... whenever that will be.
Has anyone done this yet?
Any feedback guys who have done this? Please provide what card you used so we know.
I'm tempted to do this i have a decent card samsung 64gb pro

I tried, and instead of coming up with the initial result his did when he ran the sm list-disks command of "disks 179/160", came up with "disks 179/0". I use a 128 evo as well, and it was in debugging mode and had accepted my computer, etc. I ran every deviant I could think of and it changed nothing.
I used an Evo plus 128gb and worked like a charm.

What's the purpose of Adoptable Storage? Does it basically turn the memory into one giant "partition?"
Sent from my SM-G935T using Tapatalk
I tried this and never got it to work. Kept showing 179:0 like it wasn't seeing my sd card.
I have a 128gb Lexar high speed MicroSD i picked up from Amazon and i've had zero slow downs. I believe the SD Transfer rate is around 95mb/s so there should be zero issues with it. I did a 50/50 partition according to the guide.
Should note though - some guy says in the comments on MoDaCo's site that you can just download a terminal app and enter the commands directly. well, he's not correct. You can if you have root. Since i actually use Samsung Pay, i am not going to root this device. You need to use ADB as it states clearly in the instructions. That will work fine.
Just FYI.
Amended to say I tried just skipping to the next step, regardless of the 0, and it worked And no slow down so far
I got the same thing. Use a comma instead of the colon.

I'm frankly afraid to do that. When I ordered the phone I also ponied up for a Lexar 1800x (u3/UHS-II) 64GB card. It's expensive and really fast. It tests out in the supplied usb 3 reader on my windows pc at 175+ MB/s write speeds and somewhere in the 90's on read using winsat.
In the phone read is 68 write is 54, which I guess is telling me the sd card reader in this phone is very slow?
The internal memory tests out at 275/93
When I move apps to the sd card the boot process of the phone takes several minutes with multiple errors that all seem to be related to the incredibly slow read speeds of the sd reader. Once it's booted up it's good enough, but I don't know how adoptable storage would affect this. I guess this is probably why it's not enabled. I want to wring the necks of everyone that complained loudly that slow ad-on storage was somehow better than fast built in storage in the 6. I really would have preferred a usb c port and 128GB of internal ram to the sd reader.
Maybe someone can tell me if there's something I can do to speed the card up? Are other people seeing these kind of slow card speeds in test apps? I'm using Disk Speed Test.
I'm tempted to do this too, I just got a Samsung 128GB Pro+ which should be no problem, I might try it once I ran out of space (SOON).
Alright, I finally got a chance to format my Samsung EVO 32GB card. I followed the instruction from my original post. The only hiccup is that my SD card showed as 179,0 but I don't have any issue formating with that info.
I restarted my phone several times and I don't notice any slow down, boot issues, or slower boot up time. I haven't bother to retest my system, but I'm pretty sure the phone is slower with adaptive storage (and my card isn't the fastest out there). As for real world experience-wise, I don't feel the phone is any slower than before.
The key thing is that once you formatted SD card, make sure you go to Settings > Storage > SD card > More. Select Migrate your data. That will move your photos, music, sounds...etc to your external storage right away. Oh, and it seems like the default app storage is still internal memory. So, I have to move the app after any new app install.
Now, there are 2 issues/concerns I have. First, the total internal/external capacity that being displayed by the system is kinda of funky. I don't think the info is correct. And when you mount your phone to Windows/Mac, the external storage isn't displayed while the total storage isn't accurate either.
Second, I understand that I can't move pre-installed apps/system apps to external storage. But I'm not sure why certain user installed apps can't be move to external storage.

There appears to be an issue with your read/write speeds. Here's my test on the S7 Edge from T-Mobile. This is a Samsung 32GB card. But notice that even your built in storage is considerably slower...

OK, so one important point that "Recent Test" is not of your SD card it's of the virtual sd card that is built into the phone. So it's a test of the internal memory. To test the sd card, you have to click that red button, not the blue one. The Yellow and Green buttons both do the internal memory, just using different folder paths to the same physical storage space.
As to the faster write speeds, the tests will vary depending on what the phone is up to, and I think my result is probably slower because your storage has about 5 more gigs free. This is one of the things that made me slap my head when they announced 32 GB max in the US. As storage fills up, it slows down. 32 may be enough to squeeze most apps into, but having the ability to leave another 32 free makes things way more efficient.

Have you tested the card speed inside the phone vs the max rating?
Here is mine. My SD card is the 200gb one that came with the LG V10.
