When we reviewed the Plextor M3 256GB SSD earlier this year our verdict was pretty positive. That model is based on the Marvell 88SS9174 controller combined with 24nm Toshiba ToggleFlash NAND chips. Its performance was excellent, the warranty impressive (five-year factory warranty) but the price was a bit steep in our opinion.
A lot has happened in the world of SSDs in the few months that have passed since then. We've witnessed the arrival of new models such as the OCZ Vertex 4, but also the beginning of a price war. Many popular SSDs such as Crucial's m4 and Intel's new SSD 330 series are in the meantime available for significantly less than £1 per GB.
Plextor has yet to join the price race to the bottom, and instead says it prefers investing in performance and quality. For a short while now the M3 Pro has been available in the M3 series, and its specifications indicate improved performance. Hardware.Info tested the 256 GB model.
