Difference Between SAS and SATA Dard drives

Difference Between SAS and SATA Dard drives :

Serial Attached SCSI (SAS) :

Evolution of parallel SCSI into a point-to-point serial peripheral interface in which controllers are linked directly to disk drives

Its full-duplex signal transmission supports 3.0Gb/s. In addition, SAS drives can be hot-plugged.

SAS is designed for mission-critical enterprise applications and performance oriented applications

SAS can support cables up to 8m long,

10k to15k RPM

24 hours/day - 7days/week

Inexpensive, large storage capacity. (upto 3 TB) Serial ATA (SATA) : Serial ATA is an evolution of the Parallel ATA physical storage interface Transfer rates for Serial ATA begin at 150MB/s whereas SATA is a general-purpose interface common in the consumer market. maximum cable length for SATA is 1m. 7.2 RPM 8 hours/day - 5days/week Expensive and small storage capacity (600 and 900 GB)
