Slow file transfers - 8525, TyTN, MDA Vario II, JasJam General

Hello!
I'm just wondering why is it phone so slow reading memory card? even transferring files via activesync is over 10 times slower compare to if transfer to/from the card via usb adapter.
Then, if you install every problem on SD, then the phone become very slow.
IMO it's a lie saying that the phone supports USB2.0 when it's barely reaches USB1.1 speeds internally and externally

ActiveSync/USB slow/unreliable- worth getting a card reader?

With the issues i have using Activesync (losing connection and killing my USB internet connection) and the fact that large file transfers seem way to slow (even with USB 2), would a card reader for my PC (non USB, wired to motherboard) be much faster?
Thanks.
yes! it is definitly worth buying if you want to transfer large files.

MicroSD card performance

I've noticed that copying files to the phone (to storage card) via USB cable is painfully slow (as compared to say regular USB stick).
Would purchasing a high speed MicroSD (e.g. Sandisk Premier) help or is the phone itself the bottleneck?
Thanks!
Try connecting your phone as a mass storage device, if you haven't done that already.
You can select this when you plug in the usb cable.
Accessing the storage card is way faster then.

I have purchased SanDisk Mobile Ultra (Class 6) and the performance increase in real terms is marginal!

It would certainly help. Also search this forum for tnyynt's SD Tuneup cab. Note that installing that cab only makes much of a difference once you got a faster SD.
The transfer speed of the SD is limited for whatever reason, power preservation, whatever, it's limited to optimize for slower SD cards. So The SDTuneup cab ups this limit, meaning you will notice a much bigger speed difference when using faster SD cards.
i also find the msd card speed poor. especially when you open up a folder with a lot of images every image software takes minutes to scan the folder.
that is very lame

USB data transfer speed?

Hi guys,
I currently have a XDA Orbit and I'm thinking about buying the Touch2. The problem with the Orbit is the combination of poorly accessible microSD card and veeery slow data transfer rate via USB. Unless this hasn't been improved dramatically in the Touch2, it would be no buy for me.
Does anyone have some MB/min data?
It depends on the connection mode choosen. When choosing to connect it as a "disk", copying a 142MB folder takes about 35s, so it gives about 4MB/s. It probably also depends on the SD card speed and number of files to transfer.
I use already for some yrs "tnyynt tune up". Install attached CAB. Also your PC has faster and slower USB ports, select the right one.
Assume you connect storage card directly to PC and not via phone because that goes much slower.....
Have used several HTC devices (with Mega software) and speed was never a problem.

Transfer data from pc to TF101 too slow

Hi all,
I use usb cable to transfer game data to TF101 (around 1GB, 4500 files), but it's too slow (take almost 2 hours).
Have you got this problem? Copy 1 file is OK (1GB), but what problem with large amount of file?
I guess its because multiple files all have to go through one by one

Its normal. Flash chips arent very good at handle small files, and the TF is no exception. In fact, its quite bad.
Even my SSD Disc, which is capable of writing files at ~550MB/sec, struggles with a lot of small files, down to speeds as low as 10MB/sec.
Theres nothing you can do about it. Its just the way flash chips works today.
But it's strange that Samsung GS II do much faster than my TF101.
And also HTC HD2 (around 15-20 min).
I have tested, copy to internal memory and sdcard have the same problem (use usb cable).
Slow transfer speeds when connected via USB do sound familiar. But it seems this is not caused by a slow SD card. If I plug the MicroSD card into the card reader of my laptop, transfer speed is much higher than copying data to said card when connected via USB and plugged into my Transformer.
Seems the bottleneck is the MTP protokoll or the Transformer itself.

Its not strange. Those devices have faster flash memory than the TF.
Also, the cardreader in the TF is also very slow, compared to your average card reader for a PC/laptop.
Even the card reader in my N7B is slightly faster than the TF, despite being more than half the price of a TF.
Using ADB to transfer files, the N7B manages an average of 5.2MB/sec, while the TF only manages around 4.8MB/sec using the same card (class 4 iirc). It may not sound like a huge difference, but calculate that on a large file and the speed difference is a lot more noticable.
The TF is faster than the N7B on small files though, thanks to the faster CPU, but not by much, only around 0.2MB/sec difference.
TL;DR The TF's cardreader and flash memory sucks.

MTP sucks too. It was much faster to transfer files in HC using USB Mass Storage mode.
You might want to try TeraCopy if you have a PC. Set it as the default handler for file management/file explorer and transferring data should be much faster. Good luck.

I wouldnt know, I only use adb to transfer files and, to my knowledge, MTP doesnt affect that.
But yes, mass storage is always preferable to any other sad excuse for filetransfer (if not using adb, that is)
I have noticed this as well. Always chalked it up to the fact I was moving files to an external MicroSd card.
use wifi and ftp sharing mode (file expert)
I think I've read somewhere here in this forum before that the problem in the slow file transfer occur because of the honeycomb file system which i think it's the same as ics. you can search about this .
For me this is very annoying , usually I mount my sd card in laptop and copy my files because this is much faster than copying directly to the tablet via usb. With my galaxy note i do not need to do that , Note's MTP is very fast.
Heh funny thing.. I reformatted my PC yesterday, now I cant get speeds higher than 2MB/sec using adb, compared to at least 4MB/sec before
**** knows whats wrong, as Im using the same usb port and drivers as always

Extremely slow file transfers in both USB 2.0 and 3.0 modes

I'm trying to pull about 40GB of files off my phone. When I transfer the files, its progress moves very, very slowly. After a few seconds of transfer, my SSD's active time goes to 100%, lagging my entire computer to the point that I can't use any programs. My 240GB Intel 520 SSD's response time goes from 0.5 to 1.5 ms response time to 3,000 to 4,000. Transferring files to my HDD's is faster, but still slow. The transfer rate goes min (0mb/s), max (50mb/s), min, max, repeatedly.
The files I'm transferring are split archives of about 50MB each. The USB 3.0 connection uses an Etron USB 3.0 controller. I don't have any trouble transferring files over USB 3.0, except when I use my Note 3. The experience is the same whether I'm transferring from internal phone memory or off its 64gb microSD card. The experience is the same whether the phone is in USB 3.0 mode or USB 2.0 mode.
Has anyone else experienced unexpectedly slow file transfers from their Note 3?
Welcome to the wonderful world of the Media Transfer Protocol.
I still don't know what they were trying to accomplish by removing USB Mass Storage from Android, MTP is a nightmare with anything over 500KB...
It takes me about 22 minutes to copy a 300MB .mp4. From an i7 2.9Ghz 8GB 7200RPM SATA with USB3.0. Even iTunes is quicker, and it has to convert everything!
I realized 70 mbps but only if the target is the internal memory. My sd card was too slow or the card reader in the note is limited.
