Transfer data from pc to TF101 too slow - Eee Pad Transformer General

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

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

Slow file transfers

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

MTP vs USB Mass Storage Mode

I just did some quick tests and was shocked to discover the difference in speed when moving files in MTP and USB Mass Storage modes, BIG BIG differences.
Copying over a 723MB file, I got these results:
MTP > 54 secs
USB Mass Storage > 194 secs
MTP is almost 350% faster than USB Mass Storage mode. I retried the test again and again with different files sizes, got similar results.
So what gives?
Were you moving to internal storage with MTP and your add-on microSD with mass storage perhaps? That would definitely account for a difference.

No, both to internal storage, I don't have a microSD mem in the phone.
What kind of file was it? MTP stands for Media Transfer Protocol, it might be optimized for media or something.
Update:
I just did another test with a 7-ZIP file (60MB), it took 160 seconds on USB Mass Storage vs only 22 seconds on MTP.
I can't be the only one experiencing this. Come on.
It's becoming clear now why the same amount of MP3s use to take 4x as long to sync on my Nexus One (doesn't support MTP) than on my iPhone, and why I was so amazed by the Atrix's syncing performance when I got it (had been using MTP since day one).
-----------------
It was MP4 Videos...but beings that I copied it over manually (drag and drop from Explorer), it shouldn't make a difference, at least I don't think it should. I'll try it again with a large EXE file and see if it makes a difference.
yea I noticed that too, I just dont remember how fast exactly was it but even if you dont time it, the speed difference is just tremendous...what I like about MTP is you'll still be able to transfer files even if the phone doesnt support that particular file....so yeah I think I'll be using MTP method to transfer files from my desktop pc

You're not the only one. I also couldn't believe until I needed to backup the Android and TitaniumBackup folder, and also when copying hundreds of photos.
To the Phone and From the Phone are both astonishingly fast.

microsd card

hi i just got the sandisk extreme 64gb microsd card.
suppose to be 30mb/sec right?
but when im transfering video files from PC (win8/64bit) to phone via usb3 ports/cable to card, a 4gb content is showing to be completed in 50min..
this cant be correct.. right?
the actual time that its transferred across is more like 20min.. but still it should be faster right?
i had it on usb debugging as well.
is there something wrong with my setup?

might be the card.. i transfered 3 roms to my internal sdcard yesterday, about 3.9gb and it took like 7 or 8 mins
The speeds defined for cards are the best achieved by the manufacterer with an unspecified card reader, and only for contious r/w. The smaller the chunks the longer it will take, below 4 k at best around 2 MB.
In a HAMA USB 3.0 reader on a NEC/Renesas controller in an Elitebook 8560p I could achieve 20 MB read and 70 MB write, but as soon as the notebook was used for something else or smaller chunks the transfer rate drops.
The cable was only 20 cm long, with bad cables and other controller or Hubs in beetween it can get much slower, even if you use a HDD or SSD.
USB 3.0 is like USB 2.0 was in the first years slow and buggy, but if both controller and everything else matches it's fast then the 30 MB where USB 2.0 maxes out.
Test your µSDcard in an USB 3.0 reader using ATTO and you'll know how fast it really is.

Transferring files over wifi and sd card transfers

I've been trying to transfer files to my external sd card with es explorer over wifi and also with usb from my pc. Every time the screen goes off I lose the connection and the transfer stalls and won't resume.
The card was formatted on the tablet, and is exfat. Windows doesn't recognize it and says it can't format it.
Any ideas?

More info would help us to help you.
What kind of pc, what OS, what adapter are you using for computer, what brand sd card, how big are the files, are you doing other tasks on the computer when transfering the files and have you tried reformatting on your tablet.

Except for small files, I don't use ESFile Manager to transfer them, and for me it's just as easy to pop the MicroSD card out of the tablet and put it in a fast USB 3.0 card reader than connecting the tablet to my PC with its data cable at USB 2.0 speeds. I don't do this for my Note phone because I'd have to take my multi-layer Seidio case and and back cover off to access the MicroSD card, but with the tablet the card is more easily accessible.

How is your microSD formatted? NTFS or exFAT?
I am using windows XP, standard USB cables (that came with the device), large files (movies, tv shows) of over 10gigs some of them.
it may be something as simple as my usb port on the laptop, just wondering more about transfers stopping when the tablet goes to sleep?
air droid seems pretty neat, but 100mb limit per month?
You guys should check out Samsung Link. It allows you to access/transfer/stream content from any device it's running on from any Wi-Fi network. It also works over 3/4G.
Oh yeah, it's a 64gb adata micro sd

Windows XP will not support EX-FAT unless you have update (WindowsXP-KB955704-x86-ENU.exe) found here. 3.2 mb download http://www.microsoft.com/en-us/download/details.aspx?id=19364 For 32 bit.

It's a Samsung 64GB SDXC card formatted exFAT. I'm running Windows 7 64-bit on a i7 based PC I just custom built, so it's USB 3.0 and very fast. I came from an old dual core Windows XP desktop PC (that I also built), so I know what you're feeling. Previously I would just sync or copy stuff over WiFi all the time without really noticing much of a speed difference over directly connecting my tablet/phone to my PC via a cable. But now whenever I can use my USB 3.0 card reader I do it because it's night and day different in terms of speed.
i reformatted it with windows, files are tranferring at ~13MB/s over USB2.0. Painful yes, but at lerast they are copying
i have yet to see if it works in the tablet after things are copied over. definitely easy to manage from within windows with teracopy pro, but would be nice if i could use es explorer over wifi on my home network and let the copies go overnight without waking up to failed transfers because the device went to sleep during the transfer....
.... Aaand now the tablet won't recognize the card. Should have formatted with the device, not the computer

thank you for the link.....XP recognized the card after installing the driver
i then formatted it exFAT and then i went ahead and copied over a couple 8 or 10gb files and a bunch of 1.5gb files. suddenly windows said the write delay failed and now i cant see the card in windows or the tablet.
this is getting off topic, but how do i now get anything to recognize the card? this is frustrating!

XP can return that error when moving large files esp. when you have write caching enabled. You could turn that off but it slows down you file cache.
I have also had errors in Windows 7 when moving to many large files at one time. I think the chip over heats as mine does get hot some times when I transfer large files in computer with adapter.
Can you see it in in windows - control panel/administrative tools/computer management/storage/
disk management.

It shows up as disk 1 no media.
No partitions are visible and I cannot format or anything. Perhaps i wrecked the card?

HP USB Disk Storage Format Tool - Format USB drives is my goto tool for a problem like this, but be very careful and make sure you selected the correct drive when and if you format. I have enclosed the tool, you can research it on the web if you like, search youtube.

Thanks for all your help today. I'll give it a go. If nothing else I'll just buy a new card. I'm off to Hawaii on Friday and I was hoping to have the card loaded up with media and ready to go by then.
