Data transfer - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

I am finding that moving files on and off the internal memory is incredibly slow. Is there anyway to speed it up?

How do I transfer main storage files to storage card for Htc Diamond.

I am trying to find out a way to transfer main storage files to the storage card on my htc diamond once the memory becomes too low. I tried to delete some unneeded files but I am still getting memory too low warning on my device. Are there any applications that can help with this transfer? I have tried everything short of cleaning storage which resets the phone back to manufacturers settings which means I would lose all the applications that I have downloaded.

SD card apps lag

So I've been having issues with my apps if I put them on the SD card. if I put them on the SD card they get horrible slow and laggy. Facebook for example can hang for minutes before loading what I clicked giving messages that the app is hanging and if I want to close it.
currently I'm running the Concept firmware , but even with that the Z3 runs out of internal memory very fast. and with some apps (groove) not allowing you to store data on the SD card, it gets a lot worse, making them unusable. After I installed the concept firmware I did reinsert the SD card and chose to format it so it's supposed to be an extension of the internal memory but it also doesn't seem to really work :/
Anyway right now I believe I'm running a sandisk card of some type, probably C10 if I remember right(can't really remove it right now). Is it the type/class of card that makes it work so slow on the phone ? is there some other preferred type and class of SD card that doesn't cause this serious app lag, and is there a way to then set it up so that apps that store large data and don't have a setting for SD card will still store on SD or to unify internal and SD storage as one ?
I believe it's the card. even the class 10 cards are horribly slow for use as system storage. install a sdcard speed test app and test both internal storage vs sdcard read/write speeds. And you will be shocked.
I Use Samsung pro 64gb card. And I was able to use it as system storage on concept rom. It has 90/80 read/write (*rated) speeds. And it works fine on my z3.

My S7 has started loading albums and images super slow! Otherwise performance is fine

Hi folks.
I have a totally stock phone and I have been running a san disk 128gb micro sd.
I pretty much put all my media on the ext sd and therefore have lots of memory on the phone itself. I am using about about 30gb out of the 128bg.
Anyway recently my phone is struggling to load images and gets stuck, videos are stopping sometimes. I removed the sd and did a factory reset to no avail. My next move is to format the sd but I dont want to do that because all my pictures are on it and I have no way of transferring them to my laptop.
Anyone can help?
Sounds pretty likely that the problem is with the MicroSD card
Connect your phone to your PC/Laptop using the USB charging lead, scan for errors on the card, if that doesn't help, copy the files to your machine, format to FAT32 and copy everything back to it

SD Card formatted as internal memory

I really don't recommend that to anyone, (on every phone available)
it really slows down phone. (this phone has 300/100 read/write)
And if you don't have such sd card don't format it as internal memory,
just as SD card for multi-use.
I tried with 100/40 or something SD card,
and it felt like s...
Yes, I can confirm that! My old Phone had only 16GB of internal memory, so I thought that it would be nice if I format my Class10-SD-Card as internal memory.
But it was a mistake, because it slows down the phone so much...
Also if you have a very fast SD-Card - it will not work and slow down your phone...
I've always been using microSD on my smartphones as an internal memory and have no speed issues.
It is also advisable to move all apps to the internal memory and to use the "external" internal memory only when the internal memory is full.
When the microSD is formatted as internal memory, the transfer rate drops because the microSD is encrypted (AES-128).
However, this is hardly noticeable in practice.
let alone that: The advertised microSD speeds are rarely achieved in practice.
I have more problems with a portable formatted microSD.
There are e.g. Access problems with third-party apps or file managers.

Question Encrypted SD Card unbearably slow

I got the A22 5G and I like it apart from one huge issue.
I encrypted my sd card (256 GB) and transfer rates are unbearably slow.
If I copy a 2 GB file from the internal storage to the SD card it will start ok (20 MB/s) but this is likely only the cache.
Soon it slows down to ultimately 10-50 kB/s which is unusable, copying was not finished after 15 min.
When I decrypt the card again everything is as fast as expected. I checked the SD card on another phone, no speed problems.
Back into the Samsung and encrypted it is unusably slow again.
Did anybody have a similar issue?
I returned the phone.
In case somebody else runs into this issue I'm afraid I could not determine the cause.
I tried adopting the SD card as internal storage via adp commands but Samsung has even blocked this now.
One can partition the SD card as internal storage still but it is not possible to trigger the migration.
This means any normal application will still only see the internal phone storage and not the sd card's.
Clear system cache.
Low level format the card, then format it again with the phone.
