This drive is GOOD! Used in a bespoke home-built dual-boot machine running Windows 8.1 and a ton of programmes, and connected to an 8TB Drivepool volume used to backup a NAS. If budget allows I recommend going for the 256GB over the 128GB drive as adding programs and saving data on the drive soon adds up. A perfect drive in every sense from the rapid boot time (18 seconds), to the fast Read (558 MB/s) and Write (501 MB/s) times / data transfers. Accessing programs and browsing just snaps without hesitation.Add the Samsung Magician software and you can further optimise the performance, run benchmark performance tests, and even Secure Erase the SDD when it’s time to sell. Good all round package and highly recommended.
