VERY slow Internal to SD transfer speed... - HTC Desire Eye

This is annoying... I`m trying to copy things from the internal storage to the SD card and the max speed is 1.5MB which drops off quickly to 0 .... waits... then copy's a bit more.. I mean 700MB from internal storage to SD made the phone reboot after 20 minutes and all it had copied was ~ 350MB
The SD card is a 64GB Samsung EVO so it's not a cheep version.
I also did a bench with A1 and got:
READ: 16.51MB
WRITE: 3.09MB
Reading the net it seams i should be getting way more then 2MB which pauses for 20 seconds then another burst.... it's weird
Maybe i did not format the SD correctly

SD Card Problem

I've bought a 4 Gb Sd Card yesterday, when i inserted it in my pc it asks me to format the card (showing me a size of 3800 Mb c.a.), but after i've done it now my card seems to be only 950 Mb c.a..... I've tried almost everything looking for a solution on the web (for example format again, format again but by DOS, use Panasonic SD Formatter, etc) but nothing, i can't have the size setted to 4 Gb...
What can i do to solve this problem?
Basically you must have bought a fake 4g card that is actually 1g. You can use your ppc as a storage device (using wm5torage) to format it through the pc. If it still reports 950mb you will then know for sure that it is a 1g card. The vendors have a way to trick the card to initially report a higher capacity but you will experience data loss if you use it that way without reformatting to the actual capacity.

[Q] Is really usefull a separate partition on SD for defy (2GiB internal)?

I bought a 16GiB Class 4 SD card yesterday (6-7 mb/s write, 18-20 mb/s read), and was wondering if it's a good idea to partition it. Have seen many people saying that a separate partition speed up the phone, because frees internal memory. But Defy already has 2GiB internal, with all my apps instaled on the phone (I don't install on SD) I still have 600-700 MiB of free internal memory.
Anyone here uses app2sd? It really speed up the phone? There's another choice that i haven't seen to speed up the phone with this new SD?
There is no need to use app2sd until the internal faster rom is used up.
Thanks. Was wondering if the SD card could be quicker than internal memory.

Slow write speed on sd card

i have a problem , which don't think is ROM related but any help will be appreciated
i encounter very slow write speed to my sd card (cards....i have a class 6 Kingston 16 GB, and original samsung 8 GB class 4)
when i write down files the speed is about 2MB/s at the beggining but ends at about 500 KB/s
so there are about 4-5 hours since i started to copy back the data from my sd card (about 10 GB of data) and is not over
i mention that i formated my sd card
run chkdsk, chnage cluster size from 64KB to 8KB with no visible succes
last night i alo run a defrag on my sd card ...which took hours to perform
i also noticed that at small files write speed is much slower
I would appreciate a GOOD advice, because i'm tired of "opinions" and searching the forum & Google
A big Thank You with anticipation
Is this when you access it over your phone, or from a pc?

You should not defrag a SD Card.

[Q] microSD problem

Hello,
around 20th June i've bought a Kingston 32GB Class 10 microSD.
Everything was working correctly, and all my games were running like a charm.
Then suddenly all files became corrupted, and after reboot card became unreadable.
However i managed to read the microSD by formatting it to exFAT through CWM.
I also fixed filesystem errors through chkdsk.
And there's my problem: I'm experiencing frequent graphics freezing in nearly all games (mostly in GTA SA), where they weren't present before data corrupt.
Seems like the reading speed got slower or something.
Anybody experienced similar problems or know the solution?

May be the problem is from the sd card speed . did u put a higher speed to sd card ( default is 128 kb/s ) if not u can check an app called rom toolbox that has an option to higher up or slow down the speed and check if the speed is more than 1028 kb ( the safest maximum for class 10 sd card ) and if it is 128 kb higher it up to 512 kb or so . if it didn't work try to format sd card on pc with sd card reader not with the phone and if this didn't work ur sd card is dead ....

It was 512kb. Boosting to 1024kb gave nothing.

Internal memory formatted SD card issues

I've an Samsung evo+ 256GB SD card formatted as internal storage in my HTC 10 for almost 2 years now.
2 months ago I decided to upgrade to a Samsung evo+ 256GB v2, with slightly better speeds. I simply cloned the old SD to the new one.
Everything was always fine, worked great till yesterday.
I had some weird stutters while playing music and then I noticed the UI was also getting stutterish.
Went to bed, charged my phone as I usually do. When I woke up and checked my mail the phone just froze and rebooted.
After reboot the phone told me the SD card was missing
I decided to shut down the phone and examine the SD card but the phone just got stuck shutting down, I had to force reboot and shutdown again.
I tested the SD by a full byte by byte read in Western Digital diagnostic tool for harddrives to see if my SD was broken, but it was fine, no errors.
I popped the SD back in my phone, started and the SD mounted fine, no issues so far.
Could the file system be corrupt? If it is, how do I fix it?
I could try and move the data to an external drive and reformat the SD, I've a USB 3 OTG cable. But I'm not sure how to do that either.
Will Android move the data for me automatically when removing the SD card as internal storage?
Stutters continued today unfortunately, especially when doing a SD benchmark.
I decided to use clonezilla and do a clone of the card to another one to see if that improves anything.
On the old SD I had 72MB/s read and 20MB/s write according to A1 SD bench
Internal storage 225MB/s read and 41MB/s write
On the cloned SD I have 74MB/s read and 19MB/s write
The difference is that the cloned SD is a Samsung evo+ 256GB v1 and the old one a Samsung evo+ 256GB v2
I don't get it though, doing a benchmark on a PC shows 90MB/s read and 80MB/s write.
I advice you to check media files. I had lived same problem. I found solution by chance . I attached sd card to my notebook to backup dcim and music folder. While copying the files, suddenly copy process stopped on a not special file. I removed the sd, re attached and deleted that file before continue to copy. When copying finished, i attached the sd card to phone... Whola... Without formatting or doing nothing extra the card started to work as expected
