USB copy speed is extremely slow - G2 and Desire Z Q&A, Help & Troubleshooting

USB copy speed I'm getting is max 3.2mb/s, and goes as low as 1.5, is this normal? I imagine I should be getting a lot better speeds over USB 2.0 and my SD card is a new Sandisk class 6 micro sd card.

Use the mirco SD adapter provided with Ur purchase of mirco SD card.. wire is just slow... adapter have direct contact with the hard drive.. so u would get faster transfer rate

I'm getting 8-9mb/s reading from sd to hard drive, writing from hd to sd is much slower at 2.5 - 3mb/s. This is using the original HTC usb cable.

Mmm try with wifi, there are some usuful app for this
USB is a mystic hardware somethimes have mysterious problem :s
inviato da HTC Desire Z

I have slow speed with usb too but only with Windows. If i use linux i get extreme speed over 15 Mb/s. I don't know if Windows has any restrictions...

Yeah I would just try either Bluetooth, a microsd adapter, or Wi-Fi instead.

Adapter is usually the fastest as the reader can interface almost directly with the hardware. Over USB you have several factors to consider, the speed of the port, as well as the speed of the phone (i.e.: what Mhz is it running at... and is the phone busy with something), and the speed of the internal microSD reader and so forth.
Plugging the card into the reader would be the fastest, however not very useful if you gota turn off your phone just to get the card out.
I've never tried the Wifi app route as for me the USB route has been fast enough, but can take a couple minutes to transfer say my CWM backups from the card to the computer.

USB Card Reader

Hi,
Is there any usb2 flash card reader out there that is fast?
I just bouth a sandisk MobileMate SD, a very convenient little thing, but it doesn't seem to be very fast, transferring 5b takes 30 sec roughly.
Are all readers the same, or can I buy someting with some performance?
I understand there is a limit to the SD card type you use, but c'mon, 200kb/s ???
I've got one of those 6-in-one FDD size USB2 ones in my machine, and it's pretty quick. I'd imagine most USB2 ones are going to be about the same speed. Sounds like you're getting low-speed USB rates of about 1.5Mb/s
is your USB port is ver 2
even your flash reader is ver 2
but your pc usb port is not
will not be fast
correct me if I m wrong

mini USB speed

Hi all. Just got my Touch through Bell Canada a few days ago, and so far it's great. One minor gripe I have is the slow USB 1.1 speed through the miniUSB port. I'm using Softick's Card Export to avoid having to fiddle with the microSD card cover, but transfers take forever if I'm loading on a lot of mp3's.
I've noticed specs on the Touch Dual and Cruiser list the USB as 2.0. Is there any way to upgrade the usb drivers in the original Touch? Or is it a hardware limitation?
I'm plugging it into a Linux (Debian) system if that makes any difference. Thanks.
I believe the Touch and Mogul are USB 2.0
--James
Are file transfers known to take longer when using Card Export as opposed to an actual card reader? Plugging the card into a reader gives normal transfer times, that's why I assumed the USB port on the Touch was to blame.
I am not sure. I know that it's faster doing it through my card reader on my laptop as well.
--James
After checking the transfer speed again, it does appear to be faster than USB 1.1, just not full 2.0 speeds. Looks like a limitation of the Card Export software itself.

SD card reader?

Hey guys, is there an external card reader that would plug into the micro USB port on the captivate? I've been searching for a while but all I can find is micro SD to SD card adapters when I would like to import photos from a camera right into the phone
It would be a shame to have to just use micro SD cards to use the internal slot. Thanks!

I dont know of one that exists. But if youre trying to import your pictures you are going to be better off just inserting the micro sd into your phone and then copying all the image files to the phone. Its essentially the same process you would do if you had an external SD card reader except you actually have to put the SD card in the phone.
here u go.

I'm not sure that there is such a beast that would plug into the microUSB, and if there was, I'm not certain that the Captivate has the functionality/interface to read and copy from the microUSB Slot. I'm pretty sure you need the computer as a go-between if the microSD isn't in the phone itself.
I think your best bet is directly putting the microSD from the Camera into the Cappy or you'll have to upload them to the computer first, then to the phone. Sorry
I've always wanted something like that, its a great idea but such a thing doesn't exist. Closest thing would be to get the flash drive adapter with the microSD slot built in.

Yeah, that's not really possible. For one thing it's a jack, not a plug. For another, it would need to power the device attached to it while still being able to be powered from the same port for charging. For another, it would need to be able to configure as a device or a host which would really be hard. And another, it would need to have drivers for SD readers, FAT, NTFS, and all kinds of other things.
this would probably be you best bet

Wow. I stand corrected. That's a really flexible controller chip. They should have shown a backup battery being used as well in the pics too.
a kernel with USB HOST mode,
a USB OTG cable
a USB to micro USB cable
a USB card reader
a SD to microSD adapter.
and you can do exactly what you want....
but you will need a back pack to carry all your cables and adapters.
One step could be saved with this

But nobody sells it, and who wants to splice USB cables?
This one?
Like this one?

I'm looking for the same.
How about this?

This part is odd:
- With own browser and ES browser
- File system format: FAT32 (does not support NTFS)
in general for any phone or tablet
an external hardrive like 1 or 1.5TB with USB will be a dream, u can power the drive with extra USB. But what about powering device with the screen? I think it will run out of juice much faster in this kind of setup. Your thoughts?
From the research I have done, it requires an org cable, an USB y-cable for hooking up an external power, and a from with org support. The two cables can be found on Amazon for 2-5$. You could use any USB charger or for portability... get one of the battery packs with USB output. Portable, but it is a lot to carry around.
You can also use a powered USB hub in place of the y cable.

USB 3.0 Card Reader

Hello All,
I am in search for a good USB 3.0 card reader for my PC. The internal one died so I am out for a replacement.
Any advice? I prefer amazon since I have prime but I am open to ideas! I got a class 10 micro SD card and wanted to speed up transfers a little bit over wifi and usb.
Thanks!
Why USB 3.0? There's no SD card which is as fast that it would require a USB 3.0 port.
Just buy a cheap 2.0 reader and you'll be happy.
I've got the "Revoltec Procyon 1.5" and I'm really happy with it (10 bucks).
If you think it must be a 3.0, I would recommend the "Akasa USB 3.0 SuperSpeed Memory Card Reader".

Hmmm I didn't know that about the 3.0, what about the difference between classes? Are ALL card readers faster than Class 10 cards? Or do some readers give better performance?
Thanks for the reply! I am still on the fence
