SilverStone announced a new SATA controller add-on card that uses an ASMedia 1062R controller that connects to the host system using a PCI-E 2.0 x2 connection and supports two SATA-III ports.
PCI-E 2.0 is capable of up to 4 Gbps of bandwidth, which is only two-thirds of the bandwidth required to run a SATA-III (6 Gbps) connection at full speed. This might cause a bottleneck issue for users if they connect two SSDs to the controller and access them simultaneously, transferring large amounts of data, but it shouldn’t cause a serious problem when accessing drives one at a time or with conventional HDD storage devices.
The RAID controller includes an embedded 8-bit microprocessor to help accelerate RAID and drive access functions. The controller is capable of RAID 0 and 1, and it supports SPAN as well as non-RAID functions.
There is no word on pricing or availability at this time.
