120GB to 550GB M.2 PCIe NVMe SSDs

M.2 replaced the older mSATA standard. Available in 120, 128, 240, 256, 480, 500 and 512GB sizes the M.2 SSD connects to your device via an M.2 socket using the newer PCI Express NVMe (Non-Volatile Memory Express) controller variant designed to fully utilise the capability of high-speed PCI Express storage devices to perform many I/O (in/out) operations in parallel. These SSD's can achieve read speeds in excess of 3000MB/s and write speeds over 2000MB/s making them the fastest available.

120GB to 550GB M.2 SATA SSDs

While the M.2 connector can be used for PCIe SSDs, the ones here are SATA 6Gb/s only, so the benefits over standard 2.5" SATA drives are to do with space-saving, not speed. Available in 120, 240, 256, 480, 500 and 512GB sizes they're perfect for small form factor systems and laptops, but make sure your M.2 slot works with SATA devices, and that it supports the SSD's size, both in length (2280 means 80mm long) and thickness.
