Syba SI-PEX40138 4-port SATA + M.2 B-key expansion card

Four SATA and one M.2 B-key port

This Syba SI-PEX40138 controller card adds four SATA III connections and a single M.2 B-key 2242 slot through a PCI Express x4 interface. It is built for desktop owners who need extra internal storage connectors without using a RAID configuration. The card supports data rates up to 1700 MB/s and works plug-and-play with no extra driver installation required. Four SATA cables are included in the package.

Suits builds needing mixed SATA and M.2 B-key drives

This card fits systems that have a free PCIe x4 slot and want to run both standard SATA hard drives or SSDs plus an M.2 B-key 2242 module at the same time. It is not for users who require hardware RAID functions or who need to connect M.2 drives with M-key or other keying types. Builders without an available PCIe x4 slot should look at a different solution.

Up to 1700 MB/s aggregate throughput

The quoted maximum transfer rate of 1700 MB/s is the key figure that determines whether this card can feed your drives fast enough for the workload you have in mind. If your application demands sustained bandwidth higher than this level, the card will become the bottleneck. Check your drive specifications and expected workload against this number before deciding.
