Sounds like a real quality range of flashes.
I`ve never honestly looked at the transfer rates of these drives, being as they used to be ~256/512m, I never imagined it being that important.
However, seeing as they`re now commonly 1/2/4g, I can see it being more important.
Having seen the very impressive 25mbs of the OCZ, I decided to bench the 2 I have here atm.
1 x 512m PNY - HDTach @ 10.7mbs - steady.
1 x 1G "Super*Talent" (no I never heard of them either) @ 11.7 peak - more like 9.x steady.
OCZ seem to have an impressive rating there, and an attractive price.
