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

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

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.

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.
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
Sent from my HTC Vision using xda premium
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.
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
This is a review of the Kingston DTDUO 32GB USB 2.0 Flash Drive.
I've been using a USB OTG adaptor and a normal USB drive for a while now but it was a clunky solution and had an unreliable connection. It's easy to bump and then corrupt a file mid transfer, which was also painfully slow. This flash drive is my solution to not having a micro SD slot in my phone and wanting a simple bit of storage that I can use everywhere. I anticipate travelling with it and using it as my main USB drive simply because of the ability to move things between my phone and computers so easily. It's very small and hangs off my key ring; the device has a small metal loop for this purpose but there was no string loop included. The dimensions are 27.5 x 16.5 x 8.5 mm at its largest points. The colour of the flip cover is smokey grey with a brown hue.
I found this drive at the local tech store for $25 AUD. It comes in sizes from 8GB - 64GB, and there is a USB 3.0 version also available. The build quality is decent, though the micro USB plug looks somewhat fragile (you can see a gap in the photos). Considering the notoriety of micro USB this worries me a little bit. When plugged into my phone it sits well and feels safe. It is small and easy to ignore, but this will also depend on where the micro USB port is on your phone. For my OnePlus One it sits happily at the bottom. When the device is unplugged from your phone the smokey cover protects the micro USB side. The way the device's cover flips up is a bit awkward, if you have the flat side of your micro USB port on your phone on the bottom of your phone then the little cover will face down into the surface your phone is sitting on. The way the OnePlus One port is oriented the cover stands up in the air (as you can see in DSC_5423). You could easily remove the cover, possibly without damaging anything, but this would leave the micro USB port exposed, so I probably wouldn't advise it unless it was really inconvenient.

All considered, I'm pretty happy with this little USB drive. It's very convenient and the speeds are adequate. I look forward to USB 3.0 C type devices, with a better connector and faster transfers.
I want to use my Mi Mix 2 (MIUI 9.6.1.0 Global) with a hub to transfer files (pictures) between two external storages. The transfer rates are ok-ish, but I was hoping for more. Maybe someone here knows if it can be sped up?
I want to be able to back up pictures from a SDXC card (SanDisk Extreme Pro U3 128GB) to an SSD (Crucial BX300 480GB) in the field, using my phone to move the files. The hub I got is this one: click here, and even though it's a rather cheap construction it works as advertised.
When I connect the hub to my PC (USB Type C 3.1) I get cross transfer speeds of around 85 MB/s, which is pretty much the maximum read speed of the SD card.
Connected to the Mix 2 (USB Type C 2.0) the set up only averages around 14 MB/s, which isn't bad, but less then I expected, since USB 2.0 should have transfer speeds of up to 35 MB/s. The Problem is, that moving 128 GB at that speed takes 2.5 hours, which a) is too long, and b) is super hard on the Mix 2's battery, which probably wouldn't even hold that long.
Now my first question is: Why oh why does this otherwise wonderful 2017 flagship device only have USB 2.0?!
And the second one is: Who knows a solution other than buying a Samsung with USB 3.1?
