Generic USB Drives, are they really that fast?

Hi all,

I jst wanted 2 ask about the speeds of the generic usb flash drives that are available in the market. I bought two 8GB USB drives, one a few months ago the other a week ago.

Once i got hold of them i ran some speed tests on the drives using several tools. On the 1st drive, i got readings like this:
first 50% of the drive: 12 MB/s
last 50% : 24 MB/s

The 2nd drive, i got the following readings:

first 17% : 12 MB/s
the rest : 31 MB/s


Are these for real? are these any defects of the products? Does anyone have issues like these?


tks

Here are sum pics for you.

HDTach 3.0.4 (Has the best picture of wot i'm talking about):


HDTune:




I did some real world tests too.

I copied a 781MB file which was placed right at the beginning of the drive, from the flash to my hard disk. It took me 65secs to copy it translating it to 12.0MB/s.

Then i copied the same file which was place somewhere after 1.47GB mark and it got copied to ma HDD in about 25secs. Which gives the output of 31-32MB/s read speed.

So the benchmarks are real. Can anyone confirm on these? If they've got something like mine.
