It seems like Solid State Disks (SSDs) on servers have finally arrived. Since most environments use storage area networks (SANs), it’s a huge performance boost to use SSDs unless there is a need for storage in excess of 250GB on the local drive for servers.

Going by the above article, SSDs promise 10 times faster reads/writes.

Reads 2x SSD Raid0 = .072ms * 1000 = 72ms 2x HDD Raid0 = 9.590ms * 1000 = 9590ms.
Writes 2x SSD Raid0 = .104ms * 1000 = 104ms 2x HDD Raid0 = 1.167ms * 1000 = 1167ms
