Hi guys
I'm wondering how we can copy files faster into the HOX through usb?
Using windows, I can copy at a speed of 5-7MBps.
I think because of Linux and the kernel compatibility, I can copy using fedora Linux at 26MBps. However the speed drops to about 7MBps after a while. Any ideas how to maintain the 26MBps speed?
Note that this is all using the phone mounted as disk drive.
Thanks!

5-7MB/s sounds more like the real sustainable rate than 26MB/s.
in cm10 roms is slower, but it's normal your 5-7mbps!

I'm seeing intermittent transfer speed when transferring files on the desire.
At first I thought it was caused by the aging (?) win xp. Then I tried on a win7 and the issue is there. the SD card is the 4GB SanDisk that came with the device. What happens is that I copy files over to the SD and it starts quite speedy at 10MB/s and then the file progress bar stops for a few seconds, the speed drops to about 2MB/s, and then the transfer resumes. Before the transfer is complete, the progress is stopped 3 or more times, depending on filesize.
Do you experience the same behaviour? If so, could it be because the SD is only a class 2 card? would a faster card solve this?
thank you

oh, almost forgot. when transferring from the desire to the pc
the transfer is uninterrupted and the troughput is quite high, at 8-10 MB/s. could it be a faulty card? or is this because the write speed is much lower than the read?
thanks again

I have same problem. So it's not faulty. Could be due to sd card speed, but I'm not sure. Think it was faster on my Hero with the same sd card in it.
But so far it works fine, even with the delays. I just try to ignore the delays lol
It's not a deal breaker,maibe a mild nuisance. But since I was thinking about getting a bigger faster card I'm wondering if the nuisance goes away too

Could be the fact that the SD card is only a class 2 card?
I ditched the stock card straight away for my 8gb class 6 and have had no issues with data rate.
I guess that could be the issue. Just a few minutes ago I also noticed the phone lagging a lot while copying stuff. Lagging real bad. I guess copying large movies and using the phone at the same time is a no-go
Or perhaps get a better sd card
I am using Class 6, 16 GB ... no issue with transfer speed.
I noticed that the phone is lagging only when installing apps.
Any suggestions for a good speedy SD?

Been debating whether to setup the apps2sd feature on my phone but after searching about it, not really sure if its worth it from what I gather?
is there any benefit from setting this up?
Also, will there be any negative effect if my SD card is partitioned, and I flash a ROM that does not support apps2sd?
Just thinking ahead. don't want to set my phone up for failure once I get ROM crazy (new to android).
Running DC 3.2.3 btw.
You should have at least a class 6 SD card if you're gonna do it. Basically it just frees up internal memory. You probably won't notice a speed difference on a phone this fast. However, it did improve app loading on my G1. Haven't used it on the EVO yet.

I've use it on the stock 8gb havent had not one problem also just upgraded to16gb class 2 using now not one problem running damage control 3.2.3 also when I had HTC Touch Pro ran all my apps on SD card no problem just back up your cards on hard drive disc whatever always upload your pictures via flicker dropbox

Hopefully it's just me but I am getting terrible USB transfer speeds. Like less than 1 MByte per second. It's going to take me all day to transfer over my Pics and Movies.. I think it would be faster using FTP over Wi-Fi. Anyone else seeing this?
I am using the same computer and connection that I use with my Droid 3 and the Droid 3's transfer speed is much much faster.
Mine transfers hella slow too. I think it has something to so with it not being actually mounted.

I disconnected and reconnected using a different port on the same computer and now it's more "normal" speeds. Not exactly fast but about the same speed as the Droid 3. Not sure if it was the port or just the disconnect and reconnect that did it.
that is normal for MTP transfer
if you want fast transfer speed, flash CWR and boot into recovery to mount USB
Is anyone else experiencing super SLOW transferring large amounts of files to their phone?
Umm, I guess it depends on what you mean by SUPER SLOW?
It's not instant...if that's what you mean...
I believe that is because the GNex has built in memory. Anytime I tried to transfer data from my Thunderbolt with the card inserted it would be slow. using a connector I was able to transfer ~30GB of data in roughly 1.5-2 hours. The file transfer says to expect 10+ hours to transfer 20GB to my GNex.
Works OK here...

any idea on how long to transfer how much? My transfer speed are horrible. How do you have your phone connected.
My transfer rate is decent but it won't transfer everything . I always end up missing a gig of stuff..odd

there's always ADB push it is WAY WAY WAY faster that MTP

Increased transfer speed
I was on another site and saw a suggestion to turn on USB debugging.
I was in the process of transferring a movie (1.24 GB) and the transfer time was about 1 hour for an hour and 45 minute movie. I followed the suggestion and the time dropped to 8 minutes!!!
The actual time was less than 5 to copy to my GNex. Hope this helps...

I've always had my PC tell me to expect a time that was way longer than actual transfer time. I don't think it'll take 10+ hours.
Coming from USB mass storage/sdcard on a HTC HD2.. Sorry to say but MTP has got to be the worst feature on galaxy nexus. Slow speed and Unreliable
Using windows explorer MTP transfer is next to impossible. Always freezes for me. Nothing else freezes in my system except when trying to use MTP
Using Wifi Apps such as airdroid to transfer has proven to be unreliable and slow when transfering big files or folders. It always times out.
Using windows program call QtADB_0.8.1_windows over usb to transfer my files now. It is actually quite reliable. Unfortunately, speed is still slow. I would estimate at about 600kb/sec.
Now the biggest question is does anyone got a better solution out there for transferring files with MTP?
Use adb. I've found it to be the fastest way. :good:
+1 on adb pull/adb push
I've never had any issues with mtp in windows. It seems equally as fast as any USB 2.0 connection and reliable. Provided your PC isn't a pile of **** and you have the correct drivers installed ( mind you I let windows update do all the work, no manual installation at all) it should work like a breeze.
If you're getting slow transfer speeds the culprit could be that your phone storage is low. When flash memory gets low on space it fragments the data all over thus reducing speed. Another culprit could be that your using a USB 1.0 port on your PC.

Use usb otg cable + thumb drive, its the best for me...

mtp on multiple devices has always been slow for me
and i play crysis 2/bf3 maxed on tv.
it's my low-end pc ($700)
but really, acer iconia a500, some sabsa pmp, gnex, razr xt910, and some other phone all transfer slow regardless of usb port (my corsair flash drive gets up to 100mbps transferring files in the same port).
but i have had mtp work fast a few times, 99% of the time it is laggy and it hates/doesn't allow multiple operations in the drive (one copy operation at a time, can't open two windows in the drive for ease of moving files, unreliability when internally moving files).
mtp is ridiculous it is nice that the device can access the sd card at the same time (but i could just use multi mount sd).

Thanks for the reply guys. I was hoping for a more graphical GUI interface solution. I guess i just have to learn how to usb ADB commands..

Fragmentation of data on solid state memory does NOT slow down either writes or reads. No heads to reposition, every location on a ssd is instantly available no matter where your last access was from. In fact, with sd memory it is a mistake to defragment because it just burns through the limited number of write cycles the device has, pointlessly.
That said, using a usb 1.0 or 1.1 port is sure going to slow transfers a lot, compared to usb 2.0 speeds. Usb 3 is even faster, of course, but I don't know if any android phones support usb 3 yet.
Remember that usb rated speeds are only achievable on very small transfers, too, and for longer files can get really slow, unlike firewire.

Can you push/pull entire directories or file groups with adb?

i beg to differ with this statement. On any transfer i've see tested write speeds are significantly slower for multiple small file transfer vs single large file transfer. the overhead from having to read/write the FAT information (file allocation table) for multiple small files slows even my USB3 hard drive to a crawl vs a 700 meg ISO that transfers at 180MB/s

Yes, if you are including file system overhead writes of many small files is slow on any type of connection compared to a single large file. The actual transfer speed of USB (at least prior to 3.0 anyway) is limited in the case of a single large transfer to WAY below the spec speed of USB 2.0 though, falling off dramatically from the initial speed after the first k or two have been transferred and spiking up and down from there until the transfer completes. This is due to the way Intel designed USB, to compete with Apple's (ugh...) Firewire (which has a steady full speed for any sized single file transfer).
The practical result is that for large files FireWire can move data over the link at speeds approaching its rated 400mbps while USB 2 at 480 nominally rated takes a lot longer to transfer the same file. So one should never expect to achieve USB 2's rated transfer speed for large files. For single small files you can get closer...
