I plugged a USB3 stick into a USB3 port and copied a movie of 1.2 gig. It copied at an average speed of 5.4 mb
I then plugged in an old SUB2 stick into the same USB3 port and it copied the same file at 7.22 mb.
Can any one tell me why the usb2 copied faster than the USB3?
If nothing is wrong, no technical reason for such a result.
Hit a few USB sticks that I swear are USB 1.0 sticks.
Lexar is the brand I use now. They work just spiffy for me.
Have you installed the 3.0 drivers?
I have new via drivers still makes no difference.
I tried the 2 usb3 ports on the back of the pc and the front, makes no difference, still slow as a wet week.
I got a support email for TDK the manufacturer giving no help at all.
My conclusion is the stick is useless
It would help if you posted the make/model of the drives.
What file system are you using on each drive? That can make a difference as well.
You can also test your drive speed with usbdeview and then compare them to other drives:

It is a TDK 8 gig Gold USB 3.0
Fat 32 or NTFS is the same slow speed. I tested it with the link provided
and got 6.30 MB/Sec
A TDK gold USB 2.0 did the same test and got 8.4
You're talking write speed, right? That is pretty slow for a USB 3.0 drive.
Looks like you're not the only one complaining:

FAT32 is usually faster than NTFS.
USB speedtest is USB 3.0
Speedtest2 is at USB 2
Lexar 8 GB USB 3.0 stick.
Cruzer Glide. a 2.0 stick 8 GB
Glide USB2 was USB 2.0 test
Glide USB3 was the USB 3.0 test.
Mouse over the graphic for the name.
My Go Flex. Usb2 is in the USB2 test name

have a look at the attached
Yup. The write speed is really low.
Did you look at the link I posted?

Just looked at the link you posted here and it says the max writing speed is 6 Mb/sec read speed 60Mb/sec, that is not USB 3 is it? In my opinion, false advertising!
I will return it in the morning
Ya. That is really poor write performance for a USB3 drive.
A guideline of our standard flash drive read/write speeds is as follows:
USB 2.0:
Sequential write speed range = 4~10 MB/s
Sequential read speed range = 15~25 MB/s
USB 3.0:
Sequential write speed range =10~20 MB/s
Sequential read speed range = 40~50 MB/s

And not all USB are identical. I filtered this link for the 8 GB size

If you had any important or personal data on that drive I'd wipe it before I gave it back.Quote:
