Slow in normal use [Posted on 2007-07-11]
I bought this one because I wanted a new memory stick with more capacity than my current one, and from the advertised read/write speeds I expected that it would be faster as well. When I wanted to copy a folder full of files to the stick - a job of 10 min usually - this would have taken over one hour. According to the manufacturer's forum, this is not a defect. Other people experienced the same. Figures from my measurements: Write speed for a single large file: 6 MB/sec. Read speed for a single large file: 20 MB/sec. Interesting is my normal use case, for example 400 files of average size 10 kB. My several years old 128 MB stick achieves a write speed of 50 KB/sec for this. The OCZ only 6.5 kB/sec! This makes it 7x slower than my old stick!
Garbage! [Posted on 2007-08-16]
I am just stunned at the staggeringly, unbelievably miserable write performance of this device, especially with the stellar reputation the first-gen OCZ Rally had.
I just transferred 1GB of *large* video files (HD game trailers) to the stick. Total time: 24 minutes. 24 minutes for 1GB of large files. That works out to a beyond pathetic 700KB/second! What on earth is wrong with this POS?
Transferring small files is even worse... I have spent an entire afternoon filling this stick with a few thousand files. Don't EVER copy a lot of small files to this, zip them up or something first to a single file.
Delete performance is just as bad. I have seen it take an entire minute to delete a couple of large files. When I had to delete thousands of files, I literally gave up because it was taking forever (looked like it was going to take hours), and formatted the thing.
It's like this thing's FAT (File Allocation Table) is horribly slow, and any changes to it take an unreasonably long time.
Oh, as if the above wasn't bad enough, several times I have copied a huge file to this, and then found out later the file wasn't copied properly. I was able to scan one of the non-working files using BitTorrent's hash checking (against a torrent of the same file), and guess what? The first 1% of the (2.4 GB) file was corrupted or missing, which means ~24MB didn't get copied properly. Brilliant.
The *only* bright point with this stick is it truly does have amazing read speeds... approaching 30MB/sec. But the ridiculously poor write performance makes this thing basically unusable for me in real-world use. Perhaps if you write to this extremely infrequently and read all the time from it, it would be adequate.
I have ordered an 8GB Corsair Voyager GT, and plan on destroying the Rally2 when it arrives. It's that bad.

It is exactly what it is said to be. It's fast, small and works great so far!
Great speed and price [Posted on 2008-08-04]
I've been using this for a couple of months and find it to be very fast, reliable and sturdy.
