Our server guides’ goal is to give a you a comprehensive overview of server technology. In this second part we introduce you to server storage technology and what you must consider to find decently priced, high performance, and manageable server technology.
This is a really nicely written article explaining some of the technical differences between regular IDE drives(PATA), SCSI, SATA and SAS drives. For performance and reliability reasons SCSI drives have been the preferred drive type for servers in the past. Recently I have seen where server manufacturers have been encouraging the use of SAS drives. SAS and “enterprise” SATA drives are gradually replacing SCSI drives in many areas. They have achieved the performance and reliability of the SCSI drives at a lower cost.
