[Q] Need New SD Card - RAZR HD Q&A, Help & Troubleshooting

My class 10 Kingston 64 GB SD card just died after almost a year of fairly heavy use in my Razr Maxx HD. I want to replace it with a quality brand but would like to know what read/write speeds my xt926 can handle. I mean, is it worth paying extra for 45/45 Mbps or even 30/30? Would also appreciate hearing what brands to look for or avoid or, best of all, specific recommendations. I may consider reverting to a 32 GB card (cost decision), although the 64 GB worked flawlessly up to the day it died, even though the spec says that only up to 32 GB is supporrted. I make frequent nandroid backups to the card and also store all my photos/videos and music on it and back it up on my desktop computer usually monthly. I may consider doing it weekly after this experience. Thanks.

[Q] Using a 64GB microSD?

First thread, so putting that out in advance.
I download ALOT of music, and since I wanted to sync lots of music from spotify to my phone and bring a few movies for traveling, I bought a Samsung SDXC 64GB class 10 microSD card from amazon on bf.
I've formatted it to fat32 (with guiFormat on windows and android itself), and my atrix will reconize it. But once I start syncing music to it it unmounts it after a variable amount of time.
Has anyone else been able to get a 64GB microsd to work with their atrix?
Thanks!
i dont think it would , since specs says the phone can handle up to 32 gb micro sd card , and never readed someone report about a working 64 gb micro sd card
sent from the gray stuff inside my skull
On the bionic, they say it works.
http://forum.xda-developers.com/showthread.php?t=1458992&highlight=64gb
Aren't the bionic and atrix 2 the same?
Also, I'm running magic mod jb. I read somewhere that 4.0+ has issues with sdxc, could that be an issue?
Try formatting with a different allocation size to see if it works.
Atrix2 doesn't support NTFS or ex-fat, which some other phones do.

Yeah class 10 cards are known to have issues with this phone. It really has nothing to do with it being 64GB or not, that is causing it to dissapear or unmount, but the fact that it is a class 10 card. We have had way too many issues with anything higher than a class 6 card in the atrix2. It is also noted that the atrix2 really technically does not support SDcards higher than 32GB, but I have a 64GB card that I use in several of my phones that seems to work ok from time to time, but I only use it to move a file from one of my other phones to the A2 once in a while, so long term I really don't have a lot of info on that.
Ok, that makes sense. Too bad they don't sell class 6 anymore. So I should try to find a class 6 32gb card then instead of 10?

anything that is class 4 or class 6 is know to work with out issues, no matter the size.
I have 2 class 4 32GB cards that I bought just for this phone that were like 30 USD 6 or 10 months ago, so I am sure you can find a few really cheap now. I know that the whole class 4 or class 6 and the speed thing really tend to turn people off, but I can copy 20GB of music to one card in just over 1 - 1.5 hours, so it is not too bad.

Thanks a lot Jim! Yeah the 32gb is like $20 on Amazon, so I'll spring for a couple of those. Your right, I guess you really don't need that speed anyway (I can wait to transfer my music).

By the way my 32 class six is noticeably faster than my 16gb class 4...

[Q] Is 16 GB enough

Hey guys,
was wondering what you all think about 16GB as internal space being enough or not? The problem that I'm thinking of is that "/sdcard" will get mapped to the internal memory (and not the external SD Card), and a lot of apps just go there to write stuff. Things like downloads folder etc., which default to /sdcard/download and may fill up the 16GB partition very soon.
What are your experiences in this direction?
thanks
Personaly for me its far too litle ,cuz i have got a lot of differents app ,also 4K video and timeshift video eat unimaginable amount of space
I believe Lollipop will allow you to save app data to an external storage.
Well there's at least a decent amount of onboard memory. I got by with a 32gb card for the past 3 years. Just noe upgraded to 64gb heading into my Z3v. I really only use it for old pics (from phone to phone) and keeping my entire music library on me at all times, which is like 12 gbs.
It's nice to know I'll never be worrying for space.

Even then, the difference of write/read speeds is massive between internal memory vs external SD card. I believe 32 GB should be the bare minimum for today's smartphones. Glad T Mobile thought so as well, at least for the Z3.

If you get a good card like the Samsung Pro or SandDisk Extreme you won't notice much difference (40-50 MB/s Writes). The internal flash (made by Samsung) is obviously faster due being soldered and more inter connects (like RAID).
Cheap cards like the Sandisk Ultra are slow.... (10-15MB/s Writes)

The internal memory is like 200+ MB/s, so there is still a BIG difference. Also, I don't believe the memory controller can read the full potential of the Pro and Extreme cards. I have a 64 GB Ultra (advertised at 48 MB/s read), and I only get about 39 MB/s read. I have read the same for the Note 4 in that it cannot use the full speed available from those cards.

True on both points, the card controller max is like 40-50MB/s. What I meant was I don't think you will notice much difference because, for most apps it should be fast enough and caching is still generally in the internal card. Loading big games like Asphalt may load a little slower but in use, it should not be too bad. Internal is ~240/40(R/W) Max for the klmag2geac-b001 (16GB) and 240/60 (R/W) for the 32 GB version in the D6616.
The reads are not the problem as most ops are reads anyway, but its the writes which are really low ~15 MB/s max, hence the cost of the Extreme/PRO 35-40 MB/s.
Basically what I am saying is you are right but this is your best bet.
Here is the specifications for the internal NAND if you are interested:

Internal Memory Issue

I'm not able to use any SD cards as internal memory per Android 6. I've got the Moto X Pure (XT1575) with android 6. I'm using a 128 GB SD card. I have however tried a couple of 32 and 64 gb cards. I did get an old 1 gb card to work though. The other cards work all day long as portable memory but won't format as internal. I've tried a phone reset. Motorola tells me I have to send it in. But I'm not comfortable able going without for 5+ business days. Has anybody else been able to get this feature to work on their Moto X?
I do know you need a pretty fast MicroSD Card for it to work properly. I bought a 128GB Class 10 UHS-1 card from Best Buy for like 40 bucks and I've had in for almost a week now with no issues!! See what class your cards laying around are or go for the one I was talking about, that one will work for sure!!

I don't think speed is an issue. The 1 gb card I did get to work as internal memory was from an ancient Blackberry. Could it in fact be a defective phone?

Backing up to Samsung account problem with SD card

I can get my phone to backup to the Samsung account and cloud but if my sdcard is In it takes an ungodly amount of time to calculate the amount of music I have on the sdcard so I give up.
I've switched it dso it doesn't backup my music (which is on the 128gb memory card) but it still wants to calculate it every time.
I want to be able to backup without having to take the memory card out
Any ideas?

yes
it works perfectly........... but only when the sd card is out of the phone. before backing up it seems to want to calculate how much music is on the sd card

I have a 200Gb card with loads of images and music and don't have any issues. Did you disable any services with Package Disabler pro? That might be an issue as when you restore a backup from the cloud you have to re-enable all services.
Could be a fake SD card. Did you buy it from a reputable seller? Fake cards can be incredibly slow or take ages to scan contents because they often use shady tactics to make the card appear to be 128Gb for example when accessed on a phone or PC while in reality being much smaller in capacity (2-16gb etc). These fake cards can look incredibly convincing too so dont be fooled by an elaborate copy.
Here's an app from the Play Store that can check if you have a counterfeit sdcard, SD Insight. The app isn't compatible with the S8 but if you have an older phone you can test your sdcard.

If its been with you for at least 3 phone cycles, was the speed ever really that good to begin with? It sounds like it may be an older card perhaps. Keep in mind, technology moves quick.
If you happen to be using a card that was cheap/midrange only a couple years ago, it would stand to reason that it may be underwhelming and feeling pretty slow by today's standards.
Download an app along the lines of "A1 SD Bench" and run a test for me. Post your Read/Write speed results in here for us when you're finished.
If the result of this test is poor you may want to look at the newer UHS-I supported cards if speed is becoming an issue.
I bought the card pretty much when 128gb micro SD cards were released and use it every day in the phone with no problems to play music and store pics
To be fair I presume that means it's old tech and I've been meaning to replace it. Just bought a brand new Samsung 256gb one.
Don't understand what any of the jargon means regarding sdcards and can't be bothered to test the issue.
To be fair it never occurred to me that the card is a bit long In the tooth as I've used it with the s7 edge with no probs. So just surprised the s8 struggles

Why even bother posting if you "you can't be bothered to test the issue?"
Because I decided I wanted to.
I tend to do what I want and considering the card is in 100% working order what's the point.
If times have changed and I've gotten to answer that it's old tech I can replace it with newer tech.
Thanks for your help but I can assure you I'll post what I want, when I want, how I want. I don't have to do anything I don't want to when I've already been told the card is old tech

Ah yes, I figured that was the case. It will be interesting to know if that new card solves your problem. If you still want to run a quick benchmark on your old card its not as involved as it sounds. If you use the app I recommended before you just choose your SD card in the UI and it should only take a few minutes to run a speed test.
Read speed: 33.97 mb/s
Write speed: 10:78 mb/s
Presume this is rubbish. I bought the SanDisk card the week 128gb cards were released in the UK so it's quite old now but never had any problem with it.
All photos and all my music is on the card. Never had any issues with it. Have now purchased the following:
Samsung MB-MC256DAEU 256 GB EVO Plus MicroSDXC UHS-I Grade 3 Class 10
My 2 year old 200Gb card:
Read 1692.00MB/s
Write 14.81MB/s

Oh wow, that write speed is pretty terrible. The read speed is "passable" I guess but still below average and well below the UHS-I cards.
I had one of the first 64GB Sandisk cards (around the time of the Galaxy S4 I'd like to say?) so I know what you mean but that thing was relegated to my drawer long ago after I realized just how agonizingly slooow it was.

it isn't slow
it's perfect for listening to music from and saving all pics to. perfect to the point of there would be no need to change the card. exceptional performance.
why the s8 has issues trying to calculate the amount of music on it to back-up even when i've toggled it NOT to backup music is a bit of a stupid upgrade on the s8 when the s7 was fine.
maybe samsung haven't figured out that most sd card users just throw pics, film and music on it so it doesn't need to be super fast as they've toggled off the backup option. seems to be a really strange software decision to try and calculated stuff to back up you don't want backing up lol
Objectively it is on the slow side but I understand what you mean. If all you plan on doing is copying a load of files to it once and only need it to access a few songs or pics here and there than you're right it should be fine. Let us know if you're able to solve your issue with a new card or whether the problem persists. :good:

I've used it all an excuse to buy the 256gb card though.
Is the one I've bought any good?
Samsung MB-MC256DAEU 256 GB EVO Plus MicroSDXC UHS-I Grade 3 Class 10
Its quick as hell. "Up to 95MB/s Read and 90MB/s Write speed with UHS-I, Class 10 and U3 compatibility."
It should serve you well for quite a while I'd imagine. Even I'm tempted to get one right now.

I've never had a Samsung card . Always had the sandisk ones

Question S-L-O-O-O-W external microSD memory

I just bought an A53 , stepping down from "flagships" because the newest ones all lack expandable storage.
This feature is a MUST for me!
I've found the A53's interfacing to the card slot to be so EXTREMELY slow, to make it unusable!!!
Anyone else seeing this as well?
(I'm using a 1TB SanDisk - about 75% full - that worked quite well in my previous phone)
Is it the Exynos chipset (vs. Snapdragon previously) that is causing the difference?
Is anyone here using a large capacity microSD without any noticable speed issues?
Anything I might do to improve the situation???
(Aside from sending the phone back?)
And if I have to resort to that - recommendations on a good pgone w/ expandable storage - up to 1TB)?
(Many only specced to 256 GB)
What is slow? From internal memory to SD card or via Cport to SD card?
Is it a V30 rated card ie Sandisk Extreme?
On my N10+ with a V30 rated Sandisk:
Internal write 3.4-4gb @ minute
External write 1-2.2 gb @ minute, I believe it was.
An external transfer takes about 3.5 hrs for 400gb of data. Rates very somewhat depending on file structure and type.
The .5tb Sandisk Extreme is slightly faster. Both stream high res vids with no issues. Zero problems with both.
Once in the phone format card with phone before using. Do not remove the card once installed; instead do data transfers via the Cport. Do Not use in other devices unless formatting in new device first as it can cause card corruption. I was able to transfer my older .5tb card to my new N10+ without a format with no issues. However in general I don't recommend this practice. A corrupted card is a very rude surprise.
A used N10+ in good condition trumps a newer midrange Samsung especially if 5G and variable refresh rate display aren't important to you. It's a beast that runs like a she bat out of hell.
Many thanks, Blackhawk for your prompt and helpful reply!
Simply reading from the SD card, and getting a listing of files in s folder is very slow.
Here's an example:
Moving files from one folder to another on the SD card...
9634 files, 12.7 GB ; has taken over 29 HOURS
That's 2 hours per gigabyte.
Other transfers from internal memory to SD are also very slow, and often fail
depending on the file manager I try to do it with.
The card is a SanDisk 1TB Ultra MicroSDXC UHS - 120MB/s, C10
and as I mentioned, it has worked fine on my previous phone.
I've tried several different file managers with varying results.
They vary from completely inoperable to barely functional.
(The 2 hours per gigabyte is the BEST I could come up with )
The card was formatted in the old phone, and some transfers in and out were with a Windows PC in between.
I'll try offloading the contents to another drive and formatting in the A53 before copying back again.
5G is important - and a Note 10+ 5G would be an available option - but only available as refurbished now.
I may go there if the reformat experiment doesn't pan out.
Thanks again!
This is the one that you wanted for best speed. V30 rated. Even so your transfer rates aren't even near the ballpark.
Try reforming the card in the phone. Maybe a bad card; always buy from a reputable source, if it seems too inexpensive it's likely a fake. They are out there! B&H Photo, Western Digital and Amazon are good sources.
Unlikely it's the phone but check the contacts and clean the SD card contacts with anhydrous isopropyl alcohol. Never touch the contacts.
I don't recommend the N10+ 5G variant as it's a first generation 5G and will likely chew up battery life. 4G works well enough to stream vids and many sites cap their downloads making 5G irrelevant. New N10+'s may still be available if you look hard enough. I picked up one 9 months ago, not cheap but in a factory sealed box, perfect condition and running on Android 10.
Although I prefer Pie, 10 is ok, 11 not so much because scoped storage is fully active, 12 I won't touch. Pie is relatively secure unless you do stupid things. This device in my hand load is over 2 yo still running fast and stable.
Snapdragon is the preferred variant (better chipset and heat sink) unless you want to root.
The N10+ has maybe the best display available in terms of white point, color calibration/accuracy and gamma. The variable refresh rate displays are extremely hard to calibrate across the multiple display rates/brightness levels. As such the N10+ likely beats out even the newest Samsung flagships in these specs. Color accuracy is important to me; without accurate color calibration the gamma calibration sucks.
I deliberately chose a new N10+ over the N20U because of the above plus better form factor, the spen is on the right side, better SOT and reliability. The only repair my N10+ has had is a replacement battery. It looks, feels and runs like new. It's a gorgeous beast even today and a blast to use.
