You can do a pretty easy calculation based on the #/type of drives to determine the approx number of raw IOPS that are available, since it's I/O intensive your probably best off with RAID 1+0, which further simplifies the calculation, parity based raid can make it really complicated. 7200 RPM disk = ~90 IOPS 10000 RPM disk = ~150-180 IOPS 15000 RPM disk = ~230-250 IOPS SSD = <many more IOPS depending on flash type> Otherwise, Iozone is a neat benchmark. SPC-1 is a great benchmark for SQL-type apps though it's very high end and designed for testing full storage arrays not a dinky server. nate
