Hello. I am having some weird performance issues with my new 8gb Kingston DT G3. First time I plugged it in my netbook and ran a benchmark, results were 16mb/s read, 9 mb/s write. I tried copying a 3 gb mkv file and transfer speed was 9.5 mb/s as benchmark suggested. After a while I needed to copy something from my desktop but to my surprise, transfer speed maxed at 4.5 mb/s there, I was curious so I ran another benchmark, this time on my desktop, and results were 23 mb/s read, 4 mb/s write this time. I tried troubleshooting with no luck and the weird thing is, write speeds are kind of unstable on my netbook. So far I've tried; - both Fat32 and NTFS with different cluster sizes. - Switched to Better Performance from Quick Removal - realigned the partition (AS SSD reported bad alignment so I thought it was worth a shot) - Plugging the drive to different usb ports I would really appreciate it if anyone can help me with this :)

Can you post the specs on the desktop? Different USB controllers offer different performance.

Yeah I forgot about all that :)

Desktop is pretty old; amd athlon 64 3500+ on msi k8n motherboard running Xp sp3. With a different usb stick (some old 4gb sandisk) I can transfer @ 12-13mb/s and benchmark supports this finding.

My netbook is Lenovo S205 w/ Amd E-350 and 2gb ram running Win 7 starter (32 bit)

Does the stick always work fast on the netbook?

I find data transfers to be faster on newer computers in general, and faster with Windows 7 as well.

This could just be compatibility issue between the nVidia chipset and that particular USB stick if other sticks work faster. NForce3/4 motherboards had USB bugs.

Download these and see if it makes a difference: http://www.geforce.com/Drivers/Results/1172

Also note that large single files will transfer faster then multiple small files.

Write speed on netbook for kingston drive is down to 4.5 mb/s. This is from crystaldiskmark sequential write benchmark for a 1000mb file. I've ran it 3 times for each usb port, same results. (16mb/s read, 4.5 mb/s write) desktop gives the same write result with better read (23-24 mb/s)
I will do another test with those drivers and report back. Do you have suggestions about the netbook?

Ok, so the stick has slowed down on both? If so then its the stick at issue.

We're talking about a $10 commodity item here. Running benchmarking utilities over and over isn't doing the device any favors in the overall longevity department. If it's not reliable and is giving errors, toss it and buy a new one. If you want high-performance or durability, you're going to need to spend a bit more.

I am very well aware of that :) the reason I spent time to fix this is because I thought it might be computer related, which would affect every external drive I would buy in the future. I'll probably buy a faster drive soon and find out anyway. Thanks for all the responses.

Programs that access or monitor drives can also slow them down. If you have any drive-monitoring programs installed, or even a third-party defragger that monitors fragmentation levels, those will also slow things down.

One way to find out if anything else is accessing the drive is to see if any files are open on that drive.

OpenedFilesView

Having the Recycle Bin configured to save files on a secondary drive will also slow down transfers since explorer needs to monitor the Bin to show those files in all the other drives' Recycle Bins, too.

Setting the drive for high performance in Device Manager is likely to slow down benchmarks, too. The cache holds data that is frequently accessed so if you access uncached data, the data is first loaded to the drive's buffer and then to the machine. It is loaded dirctly if quick removal is set.
