Well, I'm more accustomed to "sequential vs. random", but YMMW.
As to 67000 512 byte writes (this sounds suspiciously close to 32Mb
fitting into cache), did you have write-back enabled?
It's a sustained number, so it shouldn't matter.

As Bob
has pointed out, h/w design targeted hundreds IOPS, and
it was
hard to believe it can scale 100x. Fantastic.
Hundreds IOPS is not quite true, even with hard drives. I
just tested
a Hitachi 15k drive and it handles 67000 512 byte linear
write/s, cache
Linear? May be sequential?
Aren't these synonyms? linear as opposed to random.
