120GB to 480GB 2.5" SATA3 SSDs

Available in 120, 128, 240, 250, 256, 275 and 480GB capacities these SATA III 6Gb/s SSDs may no longer be the fastest around thanks to emerging PCIe SSDs, but they're the most cost-effective and are still easily fast enough for most users. You'll need a spare SATA 6Gb/s port to get the most from them, and a 2.5" capable drive bay - an adaptor may need to be bought, but most cases have at least one. These drives are suitable for holding an operating system, as well as numerous programs and a healthy collection of media and games.

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.
