The DataPort 4 Bay Mini SAS/SATA Storage Subsystem puts a very large capacity, high-performance, Business Class storage in a small desktop enclosure. Version available to support four fixed 3.5" hard drives.SAS and SATA both support max transfer rates up to 3Gb/s. SAS goes beyond SATA by adding full duplex data transfers, so when commands are queued in SAS, both read transfers and write transfers can occur concurrently at 3.0Gb/sec., effectively providing a total bandwidth of 6.0 Gb/sec. SAS also features dual port point-to-point architecture through multi-lane, or "wide", connections, so a 4x connector provides up to 24Gbps aggregate, bi-directional throughput.
