Cheap and Effective Hard Drive. You get the awesomeness with the price !
The Seagate ST373405LCV is a high performance SCSI Ultra 320 Hard Drive, This is a very useful and cheap for the value. It is best designed for use with a server that uses RAID. The performance as well as read and write speed is great, which also depends on how you use the hard drive and how you setup the hard drive. I personally use the hard drives in RAID-5 which gets the maximum performance wile allowing one to fail.
