The Crucial M500 doesn't set any new benchmark records, but that's also not what Crucial set out to do. Nevertheless, the Crucial M500 480 GB is one of the fastest SSDs in this segment. Moreover, the Crucial M500 480 GB has a very competitive price. Crucial has indicated that prices will likely go down even more in the coming weeks and months.
