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
I'm serious about my portable music and am trying to find the best combination of Xperia phone and SD to match an iPod Classic in file transfer speed and audio quality but I'm mostly concerned with data transfer for now.
I'm using a class 4 32GB Sandisk and want to shoot myself :crying:
My iPod Classic laughs at the speed. :crying:
Anyone using a Class 10 or any kind of Ultra SD? How's that going? Do you own/owned any portable music devices like an iPod to compare with? All I know is my Classic can transfer at least 1 song per second, usually more, with over 32GBs of music that's great or if just transferring my newest 30 songs. With my class 4 SD in my Xperia it takes about 4-5 seconds per song and I would prefer to bounce it off the wall :fingers-crossed: :good:
I'm planning to get the Xperia Sola and upgrading my SD, (upgrading headphones after that) but I'm just looking for feedback?

Use a microSD USB adapter or SDcard adapter to get 10Mb/s, if I do use the usb cable the speed is like 2mb/s
I use a Samsung Class 10 32GB SD and the speeds are very Good.

I don't get it. What's so bad about class 4 microSD cards? I use Sandisk 16GB Class 4 aswell, I don't cry about lag, because I don't have it. Transferring songs isn't that slow, I don't do it often either so no problems with it.
Or is it just that people keep wanting more and more?

As I posted above already, the issue is that I've been using various dedicated media devices for years which have consistently performed at far higher data transfer speeds. I'll say it again:
I have 32GB of music, if I transfer with an Apple device it transfers at least 1 song per second. For a large music collection, it does this very quickly as you can see. If I'm transferring the newest 20 or 30 songs in my collection, it does that in about 30 35 seconds.
If I asked my last phone or my current Android phone to do this, it takes about 4-5 seconds to transfer ONE song (or podcast). Whether it's a few minutes for just a few songs, or a few hours to transfer my whole collection, it's terrible performance and tedious.
Which brings me to my question about data speeds. I'm sure someone suggested before that it could be partly Apple cables being designed for optimum transfer speeds. I completely forgot about SD classes though, and I found the Sandisk Class 10 Ultra transfer up to 30mbps. I checked on eBay and they are not that expensive - about €30 for for 32GB. I'll get that soon and report back!
p.s. I just asked Sony about this and they said they've tested classes 2 and 4 with their phones and said that a class 10 will likely not work with their phones so not to purchase! Hmm. Mind you, many people here have bought 64GB SD cards when Sony said 32GB is the highest that you should use. I'll find someone here using a class 10!

One of the problems - the chip. Phone's motherboard and it's transfer speed. It takes a longer 'distance' for the data to travel - from the computer, through the cable, through the chip, onto the SD.
Apple devices don't use SD cards, they have built-in memory chips, which have a lot faster r/w speeds, also they use the full max speed of USB 2.0(35 megabytes per second), microUSB has a bit lower rate of speed, and certain compression to transfer faster, which doesn't happen on other devices.
On the internet, there are sometimes written only maximum speeds(like you said - up to). The Class shows only minimum speed, Class 10 having minimum of 10 MB/s for write operation.
Android devices are not the same as Apple. Everything can't be the same, because it has been built different.
And FYI, I did read the whole post.
Thank you very much for explaining that :fingers-crossed: - that was exactly the extra kind of detail I wanted to understand the technology better - which in turn allows me to make better purchases.
What is roughly speaking, the best performance you can achieve with Android using an SD? What is the best performance a micro-USB can provide? On my new laptop, I made sure to get a USB 3.0 port but I'm guessing I won't be able to use that with Android until compatible devices are released. Devices with on-board storage as large as I'd like are uncommon and very expensive, so SD it is. Would a class 10 SD be the best you could get? I would be happy with a slight decrease in Apple-type performance, but 1 song every 4-5 seconds is too bad. Essentially, what I'm trying to do is to integrate my phone and media player in one device, without paying a fortune for an iPhone.
I just found this thread with some of the same intention: http://forum.xda-developers.com/showthread.php?t=1674373
Perhaps, better micro USB cable such as: http://www.monstercable.com/productdisplay.asp?pin=4989 + class 10 SD = mission kind of accomplished?

A 32GB Class 10 SDHC is the largest and fastest kind of SD card compatible with Arc/Arc S. Some people have had luck with larger cards, but officially SDXC isn't supported on 2011 Xperia phones.
Phones currently don't support USB 3.0 as they don't have the processing power or data bandwidth to support USB 3.0 transfer speeds. You're hard pressed to find anything that maxes out USB 2.0 apart from dedicated storage - the two devices that exceed USB 2.0 speeds that I own are an external hard drive and a card reader that I use with high-speed CompactFlash. I usually get 10MB/s writes using this with my Class 10 MicroSD.
To be honest, trying to write at high speeds through the phone's system is an exercise in futility - just get a good card reader, it doesn't have to be a USB 3.0 model (which are usually rather expensive and aimed at photographers) as SDHC maxes out around 10-12MB/s writes anyway.
I got a 32 GB class 10 card with my phone when I got it. I move all apps to SD as much as possible, and also listen to a lot of music. I also take a lot of pictures and videos. So for me it was just calculated in as part of the cost of the phone when I bought it - it was a no-brainer.

You lucky thing, a 32GB class 10 SD with the phone? Hah that's great. Well how do you like the performance?
My plan is: new phone with excellent audio tech+class 10 SD+great earphones=very happy me. I'll have the phone next week, finally.
So I have a 32 GB Class 6 and runs well
YEs i used 32GB class 10 in my neo v, but you always to fomrat it when you put it in your device
I've a 16 gb class 10 Samsung sd, and run's fine whithout problems.

Well I have the same card, and I never managed to cross 7MB/s, with large files, music or videos. Not on my old system, not on my new system. Not on Windows XP, not on Ubuntu, not on Windows 7. Not on 6 different USB ports on my old system, and not on 8 USB ports on my new system. Two different USB cables are tested also.
So I'm really curious to know how could anyone manage to get 15MB/s with this phone.
Do you mind to post screenshot while transferring data at 15MB/s?

Well, FYI, I guess we are all using Sony USB cable.
However, this is great transfer rate, I never managed to achieve.

Ok, i dont know if all you are really using Original Sony USB cable or one chinese and cheaper, due to a posible damage on original one, i only posted for info.
Check write/read speed, tested with Antutu benchmark.
Like I said earlier, card is SanDisk class 10, 16GB.
I'm using 32 GB Ultra High Speed (UHS-I) microSD, works fine
also i've got cute micro adaptor with it for fast downloading from PC
my AnTuTu scores 5624
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.

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.

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...

Hi guys,
I need help.
I have like ultra slow speeds if I want to put my pictures back on my device.
For an 1,5GB folder I needed about 20minutes!!!
I don´t seems normal. Do someone have an idea, why it could be so slow?
Tested 2 cables, all the same.
Thanks for your help

Try usb3 port on your PC and usb3 cables
Hi everybody. I have a S21FE Snapdragon (G990B) version on BVB3 version so I plan to update to CVC6 and decrypt data for some testing on Afaneh's recovery.
My issue is that data file transfer is slow as hell, even if I use USB3, even with 3 differents cables and ports. Of course I don't want to lose it so I have to wait but to be clear
I've waited for 40 minutes and only approx 4-5Gb of data were copied for 65Gb in total.
Anyone else had this slow data transfer issue ?
I noticed this with a lot of small files. If you zip them, the same amount of data is transfered faster.
@DarkStar9173 Thanks for your reply. It seems to be the same for me. So I used FTP wich transfer big files slower but small files faster. I'm tired of these cables and their slow transfer speed...
I also noticed the S21 FE is extremly slow with transferring files to the pc. I compared it to the S21 Ultra and that one was very fast using the exact same cable. I have no idea why.
