The disk drive technologies have grown very rapidly in last the last years. This has resulted in the development of storage device with the capability in terabytes.
Some of the hard disk storage technologies commonly used are as follows:
1. SCSI / SAS
2. Fire wire
3. ATA/SATA
4. RAID and Fibre channel
The valid evolution of SCSI, that is SAS includes
1. Long established software advantage
2. Multi channel
3. Dual port connection interfaces found in SCSI.
SAS was defined to be the next generation of SCSI after Ultra 320. SAS would evolve to include and feature following key points:
1. Features of the SCSI base command set
2. Preempts and bypass Ultra 640
3. Mainstream production began in 2004
4. Multilane tiering
5. Offered a cost sensitive and highly reliable product
6. Universally supports SATA devices
7. Targeted for mid range to high end servers
The current implementation of SAS offer data transfer rate in excess of 3Gbits/sec. The second generation of serial attached SCSI (SAS 2.0) increased the speed of the
interface up to 6Gbits/second and the third generation (SAS 3.0) will increase to 12Gbits/sec.
The mini SAS HD cable comes in external, internal, external-internal features and offers incredible flexibility for system builders.
The advantage of using SAS over older parallel technologies includes:
1. Thinner cables
2. Longer cable lengths
3. Less bulky connectors
4. Low cost serial interfaces (vs the hardware for parallel interfaces)
5. Less cross talk (due to fewer conductors in the cable)
6. Active Optical Cables (AOC) available for increased distances
SAS has become widespread data storage interface in servers that are on target to becoming a viable contender for external storage system. You can get these storage
devices online from the online stores exclusively providing these storage devices.
