The most IOPS for your buck!
According to some really cool hardware geeks I know, these are the disks to get if you're looking for the most IOPS for your buck for a smaller server or other home computer.
With three of these disks in RAID-0 on a ICH10R or better controller, you could get upwards of 90.000 IOPS / second read and 30.000 IOPS / write perfomance. *Not MY numbers.
The recommended chunk size is 16 to 128, but 128 is the overall best performing size to go for, unless you could benefit from smaller sizes due to very specific purposes.
