[Q] Optimal SD Card?

I asked this at the end of another thread, but there was no response, so maybe it was lost/buried. I thought I'd try a new thread.
Is there an optimal SD card for the Shift? I know that with my Nook, class 4 or 6 was actually the best thing you could use. Any data on what works best with the Shift?

Never had any real problems. What problems have you had?
edit: I did have to format one time. Just make sure you format the card LBA turned off and you should be all good.

No matter which card you get. You can use SD Speed Increase or SD-Booster to increase the speed of the Read/Write of the card.

Not a one that I've heard of, or noticed. Have been using one or the other for a while. On several Shifts and on my wife's EVO4G. All different types of Micro SD Cards, from 2 gig on up to a 32gig. Different brands, always see an improvement. One thing I will say. Every phone is different as far as the sweet spot. I use SD Tools to find the best number.

Thanks for all the feedback, guys.
For the record, I use SD speed increase on my Nook and have never had any problems. And I use a class 4 Sandisk in it, because smarter people than me determined it was the best. I stand on the shoulders of giant androids, y'know?

Sandisk makes great SD cards. But a class 10 sd card is way faster than any class 4.
Class Speed
Class 2 2 MB/s
Class 4 4 MB/s
Class 6 6 MB/s
Class 10 10 MB/s

Alternatively you can create a script and drop it into the /etc/init.d/ folder containing this:
Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
It does the same thing as those apps without taking up resources.

No, it just increases the Read Ahead buffer size in Android so data is copied off the sdcard into memory in larger chunks. Constant writing is the only thing that affects the lifespan of a sdcard.

This is already built in to ScaryKernel and it doesn't make much of a difference.
Differences I noticed with SD card speed:
CPU clock speed/governor
Compcache disabled

A script does use less resources. But the downside is that all devices are different. Because of that some will see a difference with a set script, and some won't. You have to find the specific sweet spot for your individual device. That's where the apps come in handy. They allow you to adjust and test easliy until you get the right number.

Sorry vicodan, should have clarified, not personal experience. I did a lot of research before upgrading my card & went to Patriot immediately, a lot of bad experiences by other users disuaded me from pulling the trigger.
Thanks for the heads up prboy, will definitely have a look.

Yes, I understand that. But Nook owners/devs have gone to a lot of trouble to test out different classes of SD cards and found the best performance from class 4 or 6. I'm not here to explain it or understand it, I just accept their word. I'll see if I can find a succinct explanation over in the Nook forum.

Ok, too much to pick through. Here is one of the main discussions, with a link to the other.
I just figured that if higher class didn't necessarily equal better performance on one Android device, it was worth asking about the Shift as well.

You don't need an app to find the sweet spot though. All you need is Terminal or ADB and that command in the script while root. Just change 2048 to a different number and run your benchmark. Whether you use one of the Apps or the command line method once the sweet spot is found edit the init.d script and save. Next time the device restarts its automatically applied during the boot process before the Launcher is loaded speeding up the Launcher's startup and App Drawer refresh if you install apps to the sdcard.

[Q] Does a higher class SD card improve HD recording?

I know that the optics will not improve but I mean the lagging and what not? I searched and got found different answers. I have a class 2 currently and I wanna get a 6 or maybe a 10 if it will make the videos look smoother and more fluent. Can anyone confirm or deny this?

Videos come out a bit better for me with an 8gb Class 6 SD Card. I'm using CM7

I have a class 10, but even before I had the SD card, it was fine. It just saves to the internal.
Maybe if you set the default save location to a lower class SD card, it might be worse.

Slooowww sd card transfer speed

ever since i partitioned my sd card a few months back so that i could run a2sd, i've noticed my sd card transfer speeds are incredibly slow. for example, today i was transferring the updated supreme sense rom, which is 240mb, to my phone from my computer and it took close to 5 minutes to complete. this has been ongoing for a few months but i never asked about it til now!
is this normal after partitioning your sd card for the transfer speeds to be slower?

64gb micro sd card ;) = success

Samsung 64GB Class 10 UHS-1 Grade 1 70MB/s MicroSDXC Pro Memory Card
this is the one I am using just thought that I would share this for anyone else wanting to know.

Hi mate, could you confirm that sd card is working? Today I contact samsung support and they told me that only works up to 32gb.
If it support 64gb would be great! I also have doubts if only the standard sd line, or if plus and pro also works with it.

But could you use all 64 GB?
I am also considering a 64 GB microSD, but it would be useless if I could only be using 32 GB. Maybe try to drop some large files on your card to test?

FYI
I've been using sandisk 64gb class 10 without any issue
59.46GB of usable space.

Hi dillalade.
Is there any pre-requirement (maybe special formatting) for using a 64gb sdxc card with the realy? I'm using the original stock firmware, and samsung support told me only 32gb are allowed.
Thanks in advance!

Oh, i see you need to format as FAT32. But in that case I suppose it would not support files greater than 4gb, i'm right?

that's correct.

I'm using a Sandisk Ultra UHS-1 64GB card in my Relay 4G without any problems. Just yesterday had it down to about 8 GB space available, confirming it works past the 32GB barrier. I did have to do an update for Windows XP on my dad's laptop before I transferred files to my external HDD a few days ago, but otherwise had no problems there. (It wasn't till yesterday I deleted some files on the phone that had been copied to the drive - I wanted to keep some vids on the phone for a while and was handpicking them.)
Now if only I could interface directly with my 2TB hard drive (I have it in an enclosure with its own power source), without needing the laptop.

It should be possible, as our phone support USB.
I tried to find some videos on yt if that works, but only this:

But is not that subject of course, maybe we can move it or make new threat.
Seems interesting anyway.

So the trick is to format the SDCARD in FAT32 instead of NTFS. And the drawback is you can't have a file (music, movie, whatever) that's over 4GB. Okay. Can't think of what one file would be that much, so that seems like a decent compromise.
So I guess my only question is: if you're taking a file, as in drag in drop, from your NTFS hard drive on you computer and placing it on your FAT32 SDCard on your phone, will there be any problems? As well as any problems doing it in reverse?

There should be no problems in either direction, especially if you're doing it over MTP/PTP to your phone.
Another option is to format the card as ext4, which Linux and Android support natively, it's stable, and supports files up to arbitrary size (There is a limit, but it's quite a bit more than the supported maximum card size of the Relay)

I didn't think of this till you responded, but my USB 4GB flash drive is FAT32 and I transfer files from the 60GB hard drive on my laptop, which is NTFS, all the time. I typically do drag and drop, or I transfer via bluetooth.

I've never heard of ext4, but I'll research it. In any case, from the looks of it, the Relay 4G can use 64GB micro sd cards! :good: :highfive:

not working for me, at&t variant. my id shows 179,0, not 179:XXX.

That might be a blessing. My first question was going to be how much of a performance hit did you take? It would be nice to have the option though.

Curious what the performance hit is too.

the reason why it failed was cuz card is "too slow". using that sandisk 200gb card. i have a samsung 64gb pro + card in my g4, and apparently this also works for that too. tried it and success.

At least there is apparently still a safeguard to prevent most of the people crippling their phone with cheap SD cards. I hope that when Samsung adds this officially, it will limit it to at least UHS 1 U3 cards.
The whole phone memory will be only as fast as the SD inside

so if you get the 179,0 reading your saying that the SD Card is too slow to use as adaptable storage yeh?

It won't get that fast reads since it is limited to UHS-I so up to 90/MB reads/writes. Internal memory is in the 200 MB/s range so yes, it will be a huge downgrade if you use the adoptable storage.

I would like an answer for this: if I`m opening a file from sdcard (Samsung 32GB class10) and editi it, when I try to save it again, I can only do it on phone storage. Why? My sdcard it`s listed in storage like SD Card(7CD-1711)
Can someone explain, please, and tell me what to do so I will be able to save my files to sd card?
The Modaco method doesn`t work for my SM-G935F S7 Edge

I have been using this function with my 128gb Sandisk from day one.
I have moved most large apps to the SD card. In addition, I already have a part of my music collection on there as well. Have not noticed any slowdown whatsoever!

That's a screenshot of my G4.
And when I did that it showed 179,64. As it was a 64 gb card. I didn't have any real world slowness, but if u run A1 bench tool and see the read/write differences, they definitely exist.

Today I purchased a 64 GB Samsung Pro+ (Plus) micro sd card. It says it has up to: 95 MB/s read & 90 MB/s write. I benched it at 50/40 today. I manually set the adoptable storage following the procedure outlined in the MoDaco post. I used the info returned by the command that tells you what is available to use as adoptable. It worked, but is also returning a wrong storage total (I believe that the reason for this is because the SD card basically gets filled with a file that can be encrypted, so the total amount of storage that your SD card has gets added to the storage total both as it's actual space and as the file size, this is a guess but seams somewhat plausible). I am getting 73.64 GB used out of 128 GB. I have 32 internal and 64 on the sd but only 59.14. So max is 96 but it says 128 total and a lot used.

I just done this looks like it worked with a sandisk 200gb memory card but if i install a app now where will it install?. And also whats the option under storage more and migrate data for? do we need to do that?

90MB/s is nice when talking about sequential reads, but most microsd cards are going to be around 10x slower than UFS in small random reads/writes, which is where most of your phones performance is going to come from in terms of storage IO.

I think doing this stops downloading certain apps can someone try amazon sholppig or netflix says its not compatable with your device since i done this adoptable storage.
