These were second hand disks that we purchased to replace failed units (they worked), as such this review will concentrate on these disks versus the SSD alternatives in a server environment.First up, there have been long term read/write problems of reliability with SSD technology, and given their expense this is not at all good. The SSD's are slightly faster however (maybe 7%) but once you have them in a RAID 10 or 60 they show little benefit as the bigger bottleneck will probably be your network!

I purchased a ST3600057SS and was astonished at its performance.When I say performance, I am basing it output from seeker v2.0, hdparm -t, and my subjective impression from using the computer.The seeker program reveals all of the 15K rpm SAS drives to have 3 - 5 ms average access time, which is to be expected for a 15K rpm SAS drive.The Fujitsu 300GB drives averaged 136 MB/s, the Seagate 450GB drive averages 166 MB/s, and the ST3600057SS averages 201 MB/s.To put the ST3600057SS' performance in perspective, my 64GB SSD Mushkin MKNSSDCL averages 235 MB/s.

Bought 4 of these for a RAID 5 array in an old HP ML150 G6 to use as a Hyper-V VM hot standby backup host. The tech is old but the performance is good.
