~ Connect up to 4 eSATA storage devices via a single PCIe 4-lane slot
~ Total throughput up to 20 Gbps (2,000 MB/sec)
~ Port Multiplier compatible - as many as 20 drives can be connected to this controller
This 6G 4-port eSATA controller is a high performance host adapter that provides a total throughput up to 20 Gbps (20,000 Mbps) via single PCIe 4-lane slot. The controller supports any SATA hard drive, SSDs or optical drive. All drives appears as individual drive and they can be configured to form a RAID group using the RAID utility of the OS. By attaching 4 high performance SSDs, a high performance, large capacity storage system can be easily created by stripping the 4 drives using the OS RAID utility.
The controller also supports connecting Port Multiplier in individual drive or RAID configuration. When combining with four Addonics 5-port PM, as many as 20 drives can be attached to any system. It is an ideal solution for attaching many external drives to a computer.
Samples of performance measurements by CrystalDiskMark
The RAID 0 in the test result below is software RAID created by the Windows 7 OS. The controller itself does not have built-in RAID function
|Individual drive performance
(Samsung EVO-mSATA SSD rated for 520 MB READ and 500 MB WRITE)
RAID 0 of two drives
|RAID 0 of four drives
(4 x M2 SSD with 500 MB/sec READ and 120 MB/sec WRITE)
Four SSDs attached as independent drive and bench mark tested simultaneously. The total READ speed of the 4 SSDs was over 1.8GB/sec (18 Gbps). This shows the actual total throughput of the controller is very close to 20Gbps of a PCIe 4-lane speed.
SATA data transfer rate is calculated at 10 bits=1 byte
