Logical Interface / PCIe Lanes: X4. Compatible Sizes: 2230 / 2242 / 2260 / 2280. NOTE: It will not fit the PCIe x1 slot. All necessary screws are included. System requirements: A computer and BIOS (usually set to AHCI) compatible with NVMe SSD over PCIe lanes. Windows 7 with Microsoft's Hotfixes for NVMe SSD. Windows 8 and above. Linux. If after installation you get a yellow exclamation mark under the Device Manager, you may need to get an additional driver from your SSD's manufacturer. Package contents: NVMeM.2 SSD To PCIe x16/x8/x4 Card (SSD is NOT included). Heatsink with thermal pad. All necessary screws. The SABRENT M.2 2280 SSD Rocket Heatsink (SB HTSK) is the ultimate solution for your SSD heat managment needs! NVMe PCIe extreme speeds generate excessive heat. To help dissipate the heat, SABRENT has developed a state of the art heatsink using the winning combination of aluminum and copper metals. The copper is used to absorb the heat from the drive spreading it up to the grooved aluminum surface of the heatsink. This gives the heat more surface for efficient cooling, which in turn avoids thermal throtteling and maximizes the performance of your drive.
