Plextor M6e Black Edition 512GB PCIe SSD Review (Page 9)

Final Thoughts


The Plextor M6e Black Edition 512GB is a mixed bag the way it sits right now. On the performance side, the drive isn't that much better than the premium 2.5" SATA products on the market today. We still don't know about the price, but given the premium Plextor products tend to have at launch, I suspect the Black Edition 512GB pricing will be fairly high. The drive is very stable and mature, and the firmware on our test unit is version 1.05, so the company has spent quite a bit of time making changes over the past year.

Both of the M.2 PCIe based drives on the market right now are held back by the AHCI instruction set. NVMe is around the corner, but I wouldn't expect anything to hit the market on the consumer side until around Computex this June. Until then, the XP941, its successor (which you will read about next week), and the M6e products will have to hold us over. In the case of the M6e Black Edition, the drive can deliver very high sequential file transfers, but the random reads and writes at low queue depths are a bit slower than Samsung's 850 Pro/EVO, and SanDisk's Extreme PRO SSDs. What really hurts Plextor is that those products will cost less than the M6e Black Edition when it finally launches.

We suspect the difference in cost between a premium 2.5" SSD and the M6e Black Edition in the 512GB capacity will be significant. The original M6e that hit the market one year ago sells at Newegg for $570, and we expect the Black Edition pricing will be even higher given the added heat sink and revised PCB color.

Plextor backs the M6e Black Edition with a five-year warranty, and the M6e Black Edition is compatible with PlexTurbo 2.0. Since the company's first PCIe SSD released last year, the M6e Series has gotten better, but performance consistency is still a low point. Plextor has worked really hard on improving the consistency of the M6 Pro SATA drives; hopefully the next M6e Black Edition firmware will increase performance as well.

The Bottom Line: Plextor's M6e PCIe SSD is a solid product for now, but we know something faster will hit the market before the end of the year. The GC scheme sometimes works against the performance grain and would limit the use in A/V applications.
