Hard Drives - SSD

Solid-state drives are currently the fastest form of storage available, and can give your system a massive boost in application and OS load times, data transfer speeds and overall responsiveness. Their lightning speed comes from their flash memory chips, which unlike traditional hard drives have no moving parts. This makes them more reliable, smaller, lighter and less power hungry, but they can cost significantly more and have less capacity.

120GB to 480GB 2.5" SATA3 Hard Drives

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 the highest capacity ones available, suitable for holding an operating system, as well as numerous programs and a healthy collection of media and games.

500GB to 1TB 2.5" SATA3 SSDs

Available in 500, 512, 525, 960GB and 1TB 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.

270GB 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 275, 500 and 525GB 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.
