Nice. And on that note: http://www.tomshardware.com/reviews/ssd-dc-s3700-raid-0-benchmarks,3480.html They actually over-saturated the backplane with 24 of these drives in a giant RAID-0, tipping the scales at around 3.1M IOPS. Not bad for consumer-level drives. I'd love to see a RAID-10 of these. I'm having a hard time coming up with a database workload that would run into performance problems with a (relatively inexpensive) setup like this. -- Shaun Thomas OptionsHouse | 141 W.
