Final Thoughts


Plextor hit this one out of the park. The design of the M9PeY is absolutely stunning; it is literally a work of RGB art. More importantly, the M9Pe gives us something we've wanted to see for years, a challenge to Samsung's supremacy for the fastest flash-based SSD. So, is it the fastest? Not quite, but it in our opinion, the 1TB model is the second fastest flash-based SSD for consumer use on the market. It is very close to the 960 Pro, even beating it in certain scenarios. The M9Pe is considerably faster than the 960 EVO at 512GB and 1TB, and likely at 256GB as well.

We are most impressed by the M9Pe's 4K QD1 read performance. We knew it would be good, but not this good. Looking back at our Anvil, CDM, and AS SSD testing, we are seeing a new level of 4K QD1 random read performance when the data is being accelerated by PlexNitro. It is true that the 960EVO can beat the M9Pe ever so slightly when reading buffered data, but that is only when running CDM.

The Marvell "Eldora" controller at the heart of the M9Pe definitely surprised us with its robust performance when paired with good flash. Up until now, we've only tested Eldora controlled SSDs with planar flash arrays, so we didn't know what Marvell's NVMe controller was truly capable of delivering. The M9Pe showed us that Toshiba BiCS 3 is a force to be reckoned with when paired with a great controller and firmware.

The only real complaint we have with Plextor NVMe SSDs is the lack of a proprietary NVMe driver. The native Windows NVMe driver just cannot deliver the random performance of Samsung's or Intel's NVMe driver. We aren't sure why Plextor and others do not offer a similar proprietary NVMe driver because it seems like it would be easy for a company as big as LITEON. As we demonstrated, the M9Pe runs significantly better with a non-native Windows NVMe driver.

In terms of overall performance when running moderate workloads, you can expect the M9Pe to deliver moderate workload performance that is better than Samsung's popular 960 EVO and almost as good as the 960 Pro. As you can imagine, the user experience delivered by an SSD this fast is incredible. The M9Pe boots as fast or faster than any flash-based SSD we've tested to date, multitasks with ease, and never lags no matter what you throw at it. Definitely a true Tier-1 SSD experience.

With these things in mind, Plextor's M9Pe is TweakTown recommended and Editors Choice awarded.
