Hard disks come in three flavors: PATA, SATA, and SCSI. PATA hard disks must be set to one of four configurations, each of which has a different device file:?œ Primary master (/dev/hda)œ Primary slave (/dev/hdb)œ Secondary master (/dev/hdc)œ Secondary slave (/dev/hdd)?SATA and SCSI hard disks typically have faster data transfer speeds than PATA hard disks, and most systems allow for the connection of more than four SATA or SCSI hard disks. As a result of these benefits, both SATA and SCSI hard disks are well suited to Linux servers that require a great deal of storage space for programs and user files. However, SATA and SCSI hard disks have different device files associated with them:?œ First SCSI hard disk drive (/dev/sda)œ Second SCSI hard disk drive (/dev/sdb)œ Third SCSI hard disk drive (/dev/sdc)œ Fourth SCSI hard disk drive (/dev/sdd)œ Fifth SCSI hard disk drive (/dev/sde)œ Sixth SCSI hard disk drive (/dev/sdf)œ And so on
