Plextor M6e PCIe M.2 SSD Review – RAID Tested at 1.4GB/s

AS SSD BENCHMARK VER 1.6

Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs.

  1. Great review, thanks! I have a quick question: How would you quantify the “real world” performance gain of a PCIe x4 SSD over a PCIe x2?

  2. why are You so excited with useless RAID0 setup. it only increase stream read/write.Are You only copying big files from one disk to another. that is Your main task for computers? RAID0 also increase failure probability. Try RAID1 ti is more secure and gives boost for random IO reads (depends on RAID controller), random IO read is weakest area for SSD. RAID1 also makes Your data more secure. Please remember RAID0 is not RAID is antithesis of RAID. It is not redundant (R). Who uses RAID0 for keeping data, this is only test setup, no one is using it at home otherwise he is complete idiot.

  3. Nice review, thanks.I ma planning to buy such a SSD but i would ike to use it externally like a bigger and better USB stick, does anybody know if such external enclosures are planned, or is it technically not practicable(the speed limit over usb 3.0 doesn’t hinder me)?

  4. Why the CrystalDisk shows it is SATA 3. Thanks

  5. Hi, I have a question. Why Plextool shows speed: 6Gb/s (SATA 3), when the M2 interface has a speed 10 Gb / s, even if it is in the PCI-e!

  6. Did you were able to put this m.2 SSD into laptop (like Zbook) and is Zbook 15 really m.2 PCIE or only SATA compatible – in other words is this interface in current laptops only a gimmick, or is it really reaching PCIe speeds.

    • I don’t know what you are asking. there is no gimmick. M.2 is a specific form factor of PCIe and differs from former, and other custom, variations. There are two forms of M.2 and they are native PCIe and SATA. As I haven’t had the Z in my hands, I cannot address which form that might be. Sorry.

  7. From your very excellent reviews innovations in this ssd market adding through way to the PCle lane adds an educational element to my profile as speed is always something we want to improve. From comparison the Samsung XP941 seem to be the leader, yet lacks the advantage of boot capability through PCle bios recognition, where as the Plextor does.(at least from my understanding).
    My question is, if I was to Raid 0 2x256GB Plextor PCleX2 cards, do I used a double adaptor card sold by a third party, thus lose the warranty or use 2 separate cards? (or is this even possible using 2 cards on my Rampage Black MB, since open bays are limited. There are optional double adaptor cards available, just wondering how to do this correctly with Plexor and keeping everything right, since you need to remove the ssd sticker.
    Lastly, I am wondering if it might be better to wait for Samsung to “catch up”, I’m sure their technology is not behind, (judging by the benchmarks especially) it’s like I have read about the supply demand with consumer feedback and competitive influence to issue a product superior not before the time is ready, this being Software related). It’s like other areas where Samsung dominates and blows the competition away, yet Plextor and the benchmarks we see here have something to be proud about, proof being a 5yr guarantee and in real world benchmarks you may not see much difference in raid 0 anyways?

  8. Thanks for all the work you have done with M.2 PCIe SSDs. Is the hardware that allows the M6e to be recognized as a boot disk integrated in the actual M.2 SSD or the adapter? In other words, could the M6e M.2 SSD be swapped into another M.2 to PCIe adapter and the M6e still boot?

  10. Yes…unfortunately things change quickly with tech. I cannot answer whether they went with a change of heart or will only be releasing the smaller form factor to oem. Sorry.

  11. Plextor is very good .. but cheapest SSDs are crucial ones

    is it poss. you could do vs battle like reviews ? (of max two) for example these plextor and crucial ones below ?

    Thank you

  12. did you happen to take crystal disk mark benches of the drives in raid-0? I have four of the 256GB m6e’s and I’m trying to figure out a baseline. Thanks,
