Critic Reviews


Quite simply, in the higher capacity models the Plextor M6e offers storage which is unmatched by SATA alternatives. We get faster copy operations, faster reads, faster writes and faster load/boot times. All that with a 5-year warranty too. Great stuff.

Again, though, we're most excited about the M.2-specific version. On the desktop, for what Plextor is charging today, there are more compelling solutions available.

In its PCI Express form, we would pass on the M6e. We would be interested if it were sold as a standalone M.2 socket SSD at a more affordable price. For now, the M6S and M6M offer excellent performance and reliability, putting them among our most preferred SSD choices.
