Review on SI-PEX40115 - Dual M.2 SSD to PCI-e x1 Adapter with B/B+M Key Support by Javarie Malick

Purchased to create an expandable cache drive for a server with M.2 SATA drives. After installing it, the only problem I had was having to install the correct drivers. Once that was done, it recognized 2x 256GB M.2 SATA with no issues. I later added an additional 2 x 360GB M.2 SATA and no issues so far. The speed is also constant at an average of 500 MB/s. read and 385 MB/s serial. write down. Overall I'm very happy with the card and plan to buy a second one for the server's second cache drive.
