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


SSD Testing at TSSDR differs slightly depending on whether we are looking at consumer or enterprise SSDs.  For consumer SSDs, our goal is to test in a system that has been optimized with our SSD Optimization Guide, although CPU C States have may or may not have been optimized depending on the motherboard base configuration. Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch.  We even provide links to most of the benchmarks used in the report.

Test Bench With M.2

If you take a close look at our Test Bench in this picture, you might find the Plextor M6e PCIe X2 M.2 512GB SSD, IOSwitch Raijin with Plextor M6e PCIe X2 M.2 256GB SSD, and you might even catch a glimpse of our boot drive SSD, the Samsung EVO 1TB mSATA SSD.  Tucked away behind the GTX 770 is also a Mushkin Atlas 480GB mSATA SSD.


This Test Bench build was the result of some great relationships and purchase; our appreciation goes to the below mentioned manufacturers for their support in our project.  Our choice of components is very narrow, in that, we choose only what we believe to be among the best available and links are provided to each that will assist in hardware pricing and availability, should the reader be interested in purchase.

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal Disk Info, Crystal DiskMark, AS SSD and PCMark Vantage. In consumer reports, we prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.


 Crystal Disk Info provides some excellent information about the SSD itself to include its health, product information, ‘power on’ information as well as the characteristics of the SSD. We can see that the SSD is capable of TRIM as it is not grayed out as with AAM.

Plextor M6e PCIe M.2 512GB SSD CDI

 CDI identifies a fresh out of box SSD (FOB) and a healthy number of SMART attributes are identified that enable later monitoring of the Plextor M6e PCIe M.2 SSD.


For our testing of the M6e, we are going to provide analysis results for the 256 and 512GB capacities, as well as RAID test results for both combined.

Plextor M6e PCIe M.2 256 and 512GB SSDs

For our logical RAID drive, we are using a simple Windows setup where the capacities of both dynamic drives must match as we can see here:

RAID Configuration

As a bit of a comparison, we are going to be including test results of the Samsung PCIe M.2 SSD, as well as the Intel SSD 730 Series SSD, both in solo and RAID configurations.  We thought this might be an interesting mix as the Samsung is a PCIe X4 (4 lane) M.2 SSD, while the Intel 730 is the latest and greatest in Intel 2.5″ SSDs.  We will also be including the benchmark result of the Plextor M6e 512GB SSD as this M.2 SSD is the prime focus of our report.

For the full test results of all others, one can click links listed for the Samsung XP941, Samsung XP941 RAID, Plextor M6e 256GB and/or the Intel SSD 730.

    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. blank

    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.

    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)?

    Why the CrystalDisk shows it is SATA 3. Thanks

  5. blank

    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. blank

    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.

    • blank

      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.

    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?

    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?

    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.

    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

    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,
