SSD of the Week – The Plextor M6e

When building a gaming PC, the first thing you think of is speed. What is a better way to speed up your experience than to buy an SSD? But wait, you can’t just get any SSD, you need something bleeding edge to show off and brag about right? Which is why in this week’s SSD of the Week we are going over the SATA 6Gb/s barrier breaking Plextor M6e. This year at the Flash Memory Summit it even won the best of show award.


The Plextor M6e is one of the first PCIe 2.0 x2 M.2 drives on the market. Besides it, there isn’t much competition out there, save for the PCIe 2.0 x4 Samsung XP941. It is available in the sizes of 128GB ($170), 256GB($270), and 512GB($460). When first released, the M6e was sold placed in a Half-Height/Half-Length PCIe x4 adapter only. No SATA data or power cables needed. However, with the increased motherboard support for M.2 drives, Plextor is now offering them without the adapter for a bit less. Without the adapter they are $135, $235, and $410 respectively.

As for their performance, it is variable depending on capacity. Utilizing Toshiba NAND flash and a Marvell 88SS9183 controller, and in-house firmware, all capacities offer a read speed that exceed the SATA 6Gb/s barrier at 770MB/s, write speed however, scales with capacity. The 128GB model reaches up to 335MB/s writes, the 256GB reaches 580MB/s, and the 512GB gets up to 625MB/s. As well, IOPS are listed at 105,000 IOPS read/100,000 IOPS write for 256 and 512GB capacities, while they drop just a bit to 96,000 IOPS read and 83,000 IOPS write for the 128GB capacity. During our review we even benchmarked two in RAID 0 to achieve 1.4GB/s throughput speeds!

The M6e supports both legacy and UEFI BIOS booting, which makes it compatible with a broad range of systems and configurations.  This setup permits the system to initiate all of the storage devices simultaneously, dramatically reducing boot times and improving efficiency.  Driverless AHCI (Advanced Host Controller Interface) compatibility eliminates the need for any additional drivers.


Plextor also has an SSD utility you can download called the Plextool, which allows for monitoring SMART data, secure erase, and check for firmware updates.

For their quality control, Plextor uses a Zero-Failure, Zero Error mass testing standard that incorporates extensive burn-in testing of every individual SSD to ensure reliability and performance. And as an end result to this, their estimated Mean Time Between Failures (MTBF) is at 2,400,000 hours and the drives are covered by a 5 year warranty.

With its high quality controller, NAND, and in house designed firmware, the Plextor M6e is a reliable and fast SSD.  If you are in the market for something that will speed up your PC, check this SSD out and see if it is the one for you.

    I think the M6e is still very overpriced considering it’s only slightly faster than SATA.

    I think I’d just get a pair of Samsung 850 Pros and RAID 0 them on the motherboard.
