• Provides mounting for two SATA M.2 SSDs and one NVMe M.2 SSD into one 3.5” drive bay
  • Supports multiple drive lengths of 42mm, 60mm, 80mm,110mm
  • Supports PCIe NVMe M.2 SSD width up to 30.5mm
  • Improves system performance by replacing your platter drive with up to three M.2 SSDs
  • Exclusive stud easily to fix on pre-drilled mounting holes facilitate installation and removal of SSD
  • No driver installation required

There are three types of M.2 SSDs, please make sure you know the difference between them and whether your system/motherboard support them before pairing these with your SilverStone product.

SATA (B key)
Used for SATA SSDs, and interfaced through the AHCI driver and SATA 3.0 (6 Gbit/s) port exposed through the M.2 connector.

PCI Express using AHCI (M key)
Used for PCI Express SSDs and interfaced through the AHCI driver and provided PCI Express lanes, providing backward compatibility with widespread SATA support in operating systems at the cost of not delivering optimal performance by using AHCI for accessing PCI Express SSDs.

PCI Express using NVMe (M key)
Used for PCI Express SSDs and interfaced through the NVMe driver and provided PCI Express lanes, as a high-performance and scalable host controller interface designed and optimized especially for interfacing with PCI Express SSDs. NVMe has been designed from the ground up, capitalizing on the low latency and parallelism of PCI Express SSDs, and complementing the parallelism of contemporary CPUs, platforms and applications.

* B key SSD requires SATA 7 pin cable connected to motherboard to function
** Due to the different type M.2 SSD designs, if you don’t see LED indicator blinking, it means the SSD used does not support such feature.
*** MiniSAS HD SFF-8643 cable not included. If your motherboard supports SFF-8643 U.2 connector, we recommend using SilverStone’sSST-CPS04.
