Hi People,

 

Transferring files from USB to Computer or other way round is slow, it starts of high speed (MB/s) but decreases and takes ages to complete.

 

PC Specs are:

8.00 GB Ram

i5-4670 CPU @3.40 GHz

Windows 8.1 Pro 64-bit

 

Any ideas to why this is happening and any resolutions?

 

 

Thanks!

What is slow to you - can we have an actual test?

I would grab nirsoft usbview and look at details of your disk and then simple robocopy, crystaldiskmark couldn't hurt either.. Just be careful on which one you download the exe comes with opencandy.. I would normally just not even suggest such software. But if you grab the portable zip its good.

Here is the most realistic test, just simple robocopy of large file.. What do you get?

Slow compared to what?  USB (v2) has always been slow.

 

Testing, as noted above, will show you the actual throughput.  But how are you determining that it's "slow"?

What flash drive are you using, and what kind of files are you transferring - bunch of small files or large files? Are you using a USB 2 or 3 port? 

 

Try a robocopy like Bud says. Here's what I consider speedy:

One of the fastest flash drives I have owned!

tsupersonic -

Until this new Corsair Voyager GTX came out - the Sandisk Extremes were among the fastest there are - I had a 32GB, which I gave to my father, then bought a 64GB - lightning fast!

I am going to get the 120GB Corsair for my b-day gift to myself - SSD on a stick

I have seen that drive, and it sounds good. I got my Extreme 64 GB for a decent price, so I'll stick with it for now. I don't use flash drives as much as I used to.

 

I'm glad that flash drives are finally getting performance boosts. It'd be nice to have higher capacities at somewhat affordable prices.

120-130

Read speeds of 180 are not uncommon at all.  The only thing that bugs me about the 64GB Extreme is the fact Sandisk changed the firmware to make it windows 8 on a stick compatible & now the flash drive shows as a hard drive as opposed to removable disk - so the utiulities I use to make the USB bootable dont see any flash drive.

I am getting the Corsair  Voyager GTX 128GB in 2 weeks.

ON TOPIC:  The OP still hasnt even mentioned if it is USB2 or 3 and what type of media is he transferring to ?

Yeah not much we can do until the OP comes back with some info as requested by multiple people, etc.

Sorry for the late reply guys, been busy.

 

So I have tried nirsoft and crystal:

Crystal stays stuck on "perparing"

 

But I do not know how to perform the "robocopy" test

both screens show the command use to do the test ;) So what do you not understand?

robocopy <source disk\path> <dest disk\path> filename.ext

your usb from your post is only 2, so max your going to see is if I recall about 35Mbps MAX!!! More likely much less than that, from here

http://www.tomshardw...dx166,2302.html

Looks like read from usb2 kingston is less than 30 for sure, and more like less than 20.

I did a write test, but after reread of your OP you want read test so your robocopy would be more like

robocopy j: <dest\path> filename

I show from your shot that your usb is j drive. So like

robocopy j: c:\temp filename.ext

should copy the file from your usb disk to your c:\temp directory.

Looks pretty good.

 

Are you transferring large files or a lot of little files.

Generally lots of little files (pictures mostly).

In my experience write speeds on USB 2.0 suck balls when you are doing lots of little files. They do best with one large file.
