Hi, I've searched and seen many posts on slow sd's, and separately many posts on sd corrupting pics and vids, and I seem to be observing both.
The sd card is a 95mbps Samsung (uhs-1 class 10 u3) , phone is an lg g6. Phone is fine (non rooted), and all apps were working fine. Then when I started pointing apps to the SD, I noticed transfers were extremely slow (I'm only getting between 4-10mbps up and down), and in some cases things were breaking like vids, pics, and off Spotify not loading, line map downloads failing.
Ithink what is happening is the os or the SD formatting with a low buffer, is causing the low speeds, and then the apps can't handle the slowness somehow. Like if I take 10 photos quickly and video, the buffer to storage is so slow that it thinks they've failed or something.
Anyways, would appreciate any help because I feel like I've just wasted 40 dollars on an SD card.
On a side note looked wide and far to find out the G6 sd specs, to no avail other than a forum poster saying their device took the uhs-1 class 10 ok.

Has anyone noticed slow SD transfer since upgrading to ICS?
The simple copying of files from PC to SD has become unbearably slow. Even after fixing the SD (from the dialog that came up, not sure if it actually did anything) no change.
Taking the SD out and copying direct is very fast.
It wasn't like this on Gingerbread.
My Sensation is stock o/s, not rooted, I use Sense.
Note: I had posted this a few days back on a thread about reboots, no responses so reposting here as it's really a separate topic, hope that doesn't violate rules, etc.
With root, you can increase cache size your SD to 2048kb. You can also buy a faster card. What class you have now?
I had a similar problem. My file transfer was only a little slower on ICS, but it was noticeable. On top of that, my SD card would unmount without warning during larger transfers. This was on a Lexar 32 GB Class 10.
I ended up pulling the card a week ago, backing up the contents to my PC and just reformatting the thing in my PC as FAT32. It came as FAT32 from the factory, but I've read a lot of posts where people fixed their SD errors by reformatting the card in a PC.
So far, no unexpected SD unmounts, and speed might be better. Or it could be my imagination.
Not sure if this will fix your problem, but it's something to try if you have no other leads.
I have a class 10 sans disk. Didn't notice any slow down going to ice really.. Not that I can remember what GB was like sd card was misaligned apparently according to 4ext. I formatted my sd with my PC, hit the default format settings, not quick format then stuck it in my phone.
Thanks for the replies, they don't sound like my situation.
My card was always secure, and the copying is vastly different inside and outside the phone, so I can't fault the card.
Something is buffering between the phone and the card. The difference is night and day.
I can just take out the card and copy direct each time, but that's kinda stupid and inconvenient, there's got to be a better way. And I'd be surprised if it were only affecting my phone.
OK, seems I understand the issue, and seems also that I cornered the issue.
First, the card is working normally while DEVICE ISN'T SLEEPING.
Second, it happens mostly while WE'RE SLEEPING AT NIGHT or WHILE THE PHONE LEFT DEEP SLEEP (Paranormal Activity? LOL)
So, based on this: something in kernel/ROM/anything that control the power to SDCARD doesn't provide correct/adequate voltage or electricity to the SDCARD while the phone in DEEPSLEEP.
Or: the card don't want to be suspended in deepsleep, it just removing itself when instructed to sleep (this one is the card's fault).
And: any card thats been badly removed thousands times (it can do around 20 bad removal at 7h period so, count it yourself), its become broken/unusable but not fried as stated in many site). The chip broken,yes,but due to bad removal thousands times....
So, any response and research is needed on this.
Also disassembling the device to re-plug the sd/sim module flex inside doesn't help at all, so don't bother with it.
I'm really into this really, because my SIII has already killed two 32 GB Class 10 Cards... suddenly the last one was a week ago I copied a filed restarted phone to recovery and boom SD gone... so I will check this post I think that the SD card killing case was only a few people but it seems like a major problem.
This is caused by bad quality SD cards. SanDisk already admitted it as a failure on their side.
I've already spent countless methods in trying to debug and fix it. I solved it by buying a new card.
Hmm, so the moderators can delete this thread as it seems that this doesnt need any research...
Coz many also said that using Samsung's card also got this trouble...

There are security files on the SD card that are markers that can't be over written. Simply copy all your data to a pc. Then format using the note sd format. Then copy only the important files like pictures movie ect. It's a security feature just start over.
Hi Guys,
I'm having an extremely frustrating time with my audio since inserting (what I thought would be a better) SD Card.
I get intermittent audio stutter on the new SD Card with screen on or off. Mostly when off though. Frequency seems to increase when notifications come through, though, don't occur exactly or exclusively on notification arrivals.
My Phone setup: As per Signature below
Old Card: Kingston SDHC Class 4 32GB (Formatted FAT32)
New Card: Strontium NITRO 566X SDXC UHS-1 64GB (Fotmatted exFAT)
I have attempted the following to try identify the cause:
1) Tried different Player (Sony's "Music" instead of Poweramp): Stutters on both
2) Complete clean install: Issue remained on new card
3) Reformat New Card to exFAT again: Issue remains
4) Xposed Active: Old Card works, new card stutters
5) Xposed Inactive: Old card works, new card stutters
The only conclusions I can draw are that the exFAT file system is the issue or the card is faulty.
I managed to capture a stutter in log cat. These two lines are interesting:
06-23 19:45:59.983 I/AudioFlinger(833): BUFFER TIMEOUT: remove(4097) from active list on thread 0xb4343000
06-23 19:46:00.245 W/AudioTrack(2465): releaseBuffer() track 0x9cbe6000 disabled due to previous underrun, restarting
I've attached a more complete log file. You'll see this error occur several times in short succession. Hopefully someone can see something I can't.
I'm at wits' end! Help would be deeply appreciated.
No such issue here, I have a 64GB Sandisk Extreme U3. I think it maybe the card., only way to find out is to test it in another phone/tablet.
I assume intermittent slow reads / simultaneous accesses of card or CPU time allocation can cause buffer under runs, as in something/app utilizing too much CPU time while your Music is playing. I suspect the former, its the MicroSD card's intermittent slow reads or other apps accessing it at same time. It is a low end card so I assume that much.
I generally prefer Sandisk Extreme or Pro / Lexar (Micron/Crucial) / Samsung Pro / Kingston (Collaboration with Toshiba) as they make their own NAND Flash and are pretty reliable.

Thanks for your feedback. What file system is your SD Card formatted to? exFAT I presume?
I am starting to think the card is the issue. Just want to be certain before I return it. Perhaps there is a trend or another cause.
Also, not sure I agree on your statement regarding Strontium being "low end". How did you come to this conclusion?
I assumed the model being somewhat equivlent to the SanDisk Ultra / Samsung Evo low end units due to the pricing and speed tests online.
It should still be good enough for music even if it's much slower but I assume multiple simultaneous acceses by other apps or inconsistent read speeds are causing your issue.Worst case the card is dud and you need a replacement. So just try it on another device to confirm of the card is the issue.
High end is usually the SanDisk Extreme/Pro or Samsung Pro or Lexar 633x (you can actually get them cheap on occasional sales on Amazon) but it shouldn't matter much for music though unless you are using like HD Audio or something.... Makes a big difference in video recording however.
Seems the SD card I bought was defective. I replaced the card with a SanDisk Ultra 64GB. Stutters have disappeared...
Hi,
I recently bought my first smartphone: an NGM Endurance running on 4.4.2 (KitKat) with 1GB ram and 8GB storage.
Without an SD card fitted, the Camera App takes, stores, and replays Full HD videos @ 30fps with no problem at all.
When I fitted a Class 10, "SanDisk Extreme PLUS 32 GB microSDHC Memory Card" (from Amazon) the following problem appeared:
Most of the time when I switch the phone on, or wake it from sleep, and then try to take a video I usually get a, "Low Memory, Auto Change Quality" message.
The video is about half its normal size (approx 20MB for 20 secs), is stored on the SD card (but takes 40+ secs to do so!), and plays back OK.
Subsequent videos taken immediately after are about 40MB and no warning message appears (they also take only a second or two to save).
I did a factory reset via the Settings menu and it's made no difference except I don't always get the, "Low Memory..." message now.
The problem isn't entirely consistent because I think that on rare occasions a first 20 sec video has gone OK only for the problem to appear in the next.
I have a PhD in Breaking Things and would welcome any help or advice (rather than my blundering around and poking things with little idea of what I'm doing).

I tried another 32GB card with the same results.
I then tried two 2GB cards from voice recorders and they work OK!
A SD card tester app gave read and write speeds for the 2GB cards as approximately 10 Mb/s for both read and write.
I've just run the app on one of the 32GB cards and the read/write speeds are 7.42/1.99 Mb/s (!)
Am totally baffled and haven't a clue in which direction to look for a solution - help, please!

Your device may not be recognizing the new SD cards and saving the images to the internal storage (this phone has very little internal storage) I would make sure to back up anything on the SD card and reformat it via pc.

Thank you for your reply, shel692
The phone appears to recognize all the sd cards I've tried because:
a) There are no error messages
and
b) Once installed, all photos and videos are saved to the sd card instead of phone memory
Unfortunately, my camera app doesn't allow me to choose where the photos/videos are stored else I'ld save them to phone and transfer over if necessary.
Although a relatively unknown model, quite a number of NGM Endurance's have been sold in the UK (and throughout Europe - the manufacturer is Italian) but no-one else has reported this problem (yet!)

Hi guys, I have a situation with my moto g, I have the 8gb version since one week, I've installed a 128gb sdcard on the phone formated as internal storage... During a few days I've no problem with performance at all.... Then yesterday I decided to encrypt my phone and today I loaded 60gb an data, music, photos and videos.
Since then my phone is struggling from time to time to do simple tasks like opening an app or dragging the status bar down... Is nothing like that happens always or with the same apps.... Is random, sometimes I just wanna to unlock the phone and it takes like minutes for the keyboard to come up.
Anyone with an idea of what this might be? Was it the encryption? Should I give the phone time to index all the data?
I know it's not a problem from the SD card, because it's the fastest sandisk that I could get.
Since you asked in the form of a question, I will give you the best answer I can based on your specific questions...
This is probably a multitude of issues... first, setting up your SD card as internal storage will typically show down performance, although sometimes not noticably. Second, you encrypted internal storage (your SD card) this slows down your system as well. Third, you loaded 60GB of data, music, photos, and videos, which will take a VERY long time to index and put into the Storage and Media databases, and there databases also reside on the internal storage, which access to has been slowed down significantly due to being on an SD card and encrypted. These 3 things combined will likely give extremely poor performance, for a time at least.
My first question would be how long has it been since you loaded that 60GB of data? On an idle device it would take several hours (maybe days) to index it all and update the databases...
Thanks, I might have precipitated myself in thinking that something was wrong, yet today the phone locked it self a few times, one time the process system stopped responding... I will wait until tomorrow if the problem persists I will try deleting the biggest folder ( music 40gb) and if I see some improvement I will add the music in steps.
I'm pretty sure it was the encryption. My phone, with a similar setup (1GB/8GB phone, 64GB SD as internal storage, reasonable amount of media) also showed a gigantic speed loss when I foolishly enabled encryption. I tried to work with it for some days until it became clear the situation wouldn't get any better. After a factory reset, formatting the SD again as internal and copying the media again, the phone feels even faster than it was out of the box.
I've also my phone encrypted for quite a few months now (did this already on lollipop), with actually no real complaints. However since a few days I've noticed huge performance hits as well. I'm also considering a factory reset...
Thanks for all inputs , I have restored the phone without encryption and everything runs smoothly again.
