Solved Incredibly Slow Windows 7 USB Transfer Rates

July 26, 2010 at 22:54:28
Specs: Windows 7
I have incredibly slow transfer speeds from my USB flash drive to my gaming laptop.

Apparently my laptop device manager states that I have 2.0 USB ports all of which I use for the USB flash drive.

My transfer rates are about 6 mb - 10 mb... on Windows 7.

Whereas on my 8 year old desktop computer (HP), the transfer rate is SIGNIFICANTLY faster (like 20 times faster).

Any suggestions? I have scoured through the internet and this forum looking for many answers, I have yet to find any SOLUTIONS.

Please and thanks.

This is also the link to my laptop itself, so you can see the specs for yourself:

✔ Best Answer
USB 2.0 transfer rate is max 60 MB/second. Therefore, your assumption for your old HP (like 20 times faster) is not correct because 6 MB times 20 is 120 MB/sec and is in excess of max 60 MB/sec rate. If there are many many files of very small size, then transfer rate becomes very small.

Hope this clarifies.

suatcini is correct. In addition to that information I can add that using a hub of any kind may slow the transfer rate down even further.

You can experiment with moving the flash drive to another port. TWO USB ports usually share one USB controller. If the other port on the controller in use is also using bandwidth at the time or the transfer the rate will be slower.

Computers that have built in card readers may have the card reader PLUS two ports running from one USB 2.0 controller.

Your transfer rate is not incredibly slow. Look at the link below on tranfser rates for flash drives.

Clearly I was exaggerating... the word "like" exemplifies exaggeration.

How do I fix this problem?

My laptop clearly says USB 2.0 but it's not running the transfer rate at 60mb/s...

Suggestions on how to FIX this... not how to CLARIFY what my problem is... wow.

Did you read the link I posted?

First of all 60mb/s is the theoretical speed. The actual limits with perfect conditions may be closer to 40. Flash drives, don't seem to run nearly that fast. Look at the link will you?

You haven't read my post at all.
My USB flash drive transfers files MUCH faster than my laptop does.

It's not the USB it's the laptop.

Here's an example:
I transfer 3x 500 mb files from USB to my desktop computer (8 years old) - No longer than 2 seconds.

I transfer the same 3x 500 mb files from USB to my GAMING laptop (1 year old, recently bought) - About 10-15 minutes.

It's my laptop not the USB drive itself, and yes I have read your link... it doesn't help explain why my laptop transfers slower than my 8 year old dusty desktop.

8 - year old desktop = Windows XP
1 - year old laptop = Windows 7

Well, you can't transfer 1.5GB of data in 2 seconds. Or is that another exaggeration? You probably already had those files on your hard drive and you just thought you were actually transferring them.

Did your 1 year old laptop come with Windows 7 pre-installed?
Does that laptop perform all other operations fast?

Actually, no it isn't an exaggeration. In a blink of my eyes I transferred those 3 files without having to see that "estimated time" window.

And no I did not have those files on my hard drive already, I honestly should record this with a camera to show you, since it's so utterly impossible for you to believe otherwise with your infinite knowledge of transfer rates in USB transfer rates.

And no windows 7 was not pre-installed. Another fact, when I first got my laptop, it came with vista, and vista had the exact same problem as I do now with windows 7. My laptop runs everything extremely fast. I never have any problems with any kind of transfers of files to folders OTHER than my USB flash drive to my laptop.

Just be honest, you don't have a solution do you? You're just coming in here to try to fool me into believing that you actually have a solution where you really are just trying to belittle me with things like "it's already on your hard drive."

But thank you for the help though, I honestly appreciate it, at least I know now that there's something wrong with my windows 7 laptop.

You obviously don't believe numbers do you? The burst speed of a modern SATA II hard drive can't transfer 1.5GB in 2/3 seconds. So I think you don't know what you are talking about.

Do the math. USB 2.0 theoretical transfer speed is 60MB/sec. Divide 1.5GB by 60MB and see what the number is. It ain't 2/3 seconds my friend.

There may be something wrong with your Windows 7 laptop and I asked pertinent questions about it to try and determine what, but I am not going to bother now.

chances are your laptop is using the single USB controller for your mouse and fingerpad and lots of other added extra's, it doesnt mean your computer or your usb is bad, it just means that you have 1 usb controller and its doing a lot of work, so does not have the band width left to transfer at super high speeds via the two usb ports.
BUT! as the link provided is for a refurbished laptop, it maybe that there is indeed a problem with your machine, however if you buy refurbished i doubt you have any recourse,
still the standard rate of USB 2.0 means that you should not be able to transfer 1.5g in 2-3 seconds....

i hate computers!
but cant help myself....

I have similar problems with Windows 7.
I recently reformatted my hard drive to install Windows 7 Professional 64bit
Before, I had windows Vista Home Professional 32 bit

The hardware in question is a Netgear Wn111v2 USB 2.0 Wireless network adapter.
On my Vista machine, as a comparison, I saw downloads on Steam exceeding 1200kBps frequently.

On Windows 7, with the exact same computer, not only did installing the device take three hours of fussing with manually downloading and installing drivers from my grandparents laptop and using a flash drive to transfer, but I see absolutely pathetic download speeds averaging 50kBps.

This is NOT a hardware issue, This is NOT a BIOS issue. Something is wrong with Windows 7 itself and someone needs to find a ****ing fix.

If this is just a rant then ignore the comment. If, however, you want help with a problem then I suggest you start your own thread here at CN in the hardware forum.

Are you sure you have the proper drivers for your hardware installed. Windows 7 may install something that makes things work but not install the best drivers because they are not built in. You may need to provide them. The source is usually the computer manufacturer.

I have a similar problem that you described on my Intel quad 9550 system with 4 gig of memory. I was running XP Pro and did a clean install of 64 bit Windows 7 and the read rate from my SD cards, read on my Rosewill Card reader, dropped Significantly. When I have large files (like HD movie files) I don't even try to use my Windows 7 machine for downloads. I just go to my 2nd computer running XP Pro with the exact same card reader installed to download the files. The drivers for my card reader connected to the internal USB port header on my ASUS motherboard are the generic ones and if I remove them the same ones get installed on startup. I am frustrated with trying to find a solution and have no idea where to look. I know the hardware is exactly the same on my two PCs and the only difference is the Windows 7 install. Thank you for any help anyone can suggest. harrisdc_24477

This thread is old. You shouldn't piggyback on an existing thread anyway.

I recommend you post a new thread in the hardware forum. Use the Scan My System option or list all your system specs. Then describe the problem you have in detail.
