In the earlier days, IDE hard disks with the speed of 5200 RPM(rotations per minute) were used in the desktops and SCSI Harddisks with the speed of 6000 or 10000 or 15000(in latest servers) rpm were used in the Servers. The SCSI harddisks are much reliable than the IDE Harddisks. Nowadays we get only SATA Harddisks for Desktops instead of IDE due to the change of architecture and better performance and reliability. SCSI harddisks are available even today also for Servers and the current architecture for server harddisks are SAS(Serial Attached SCSI) providing very good performance and reliability at 10000 or 15000 RPM.
