Do USB Drives Come in Different Speeds?

I believe they are all USB 2.0, and compatible with USB 1.1.

If, by the remote chance you are talking about speeds as in a harddrive, no
they don't come in different speeds, as there are no moving parts within.

Well, flash memory does come in different speeds, thus flash drives should
also come in different speeds. Yet maybe the speed difference between
different flash drives is negligible, and makes no practical difference. I
do not know. Let's see if we get information from others on this.
 
They do however use different memory, with different read/write speeds, so
the actual answer to his question would be yes.
 
Agreed. I guess I was thinking from a practical standpoint, but you're
right--even if the difference is in nanoseconds.

Of course they do, but most vendors don't publish the actual R/W specs.
Vista for instance will test and reject the slow ones for use as
"ReadyBoost".
 
For video work, the faster the better. There is a difference. Slower
flash memory can cause jerky video. 150x is good.

I expect if you search long enough, you can find
crappy ones that only manage about 1MB/sec, and
more expensive ones with SLC flash memory, with
speeds closer to 20MB/sec. The trick is getting
the manufacturer to tell you how fast they are.
Not all manufacturers give out that information.

"Read Speed: 8 MB/sec
Write Speed: 7 MB/sec"

http://www.newegg.com/Product/Product.aspx?Item=N82E16820134419

"Write up to 10MBps
Read up to 24MBps"

http://www.newegg.com/Product/Product.aspx?Item=N82E16820233052

"Read speed: 34MB/s
Write speed: 21MB/s"

Note that the speeds quoted above, are under ideal conditions.
If you transfer many tiny files, you will not get those figures.
Transferring small fines is very slow. The way to get a figure
like that, is to transfer a 1GB file and time how long it takes.
Then you'll get close to the MB/sec figure. If you have many
tiny files, it may be better to ZIP them up first, before
transferring them.
