How We Test Plextor's M6e SSD

Plextor M6e 256 GB PCI Express SSD Review: M.2 For Your Desktop
By

Our consumer storage test bench is based on Intel's Z77 Platform Controller Hub paired with an Intel Core i5-2400 CPU. Intel's 6- and 7-series chipsets are virtually identical from a storage perspective. We're standardizing on older RST 10.6.1002 drivers for the foreseeable future.

Updates to the RST driver package occasionally result in subtle performance changes. They can also lead to some truly profound variance in scores and results as well, depending on the revision. Some versions flush writes more or less frequently. Others work better in RAID situations. Builds 11.2 and newer support TRIM in RAID as well. Regardless, results obtained with one revision may or may not be comparable to results obtained with another, so sticking with one version across all testing is mandatory.

    Nice product design, please make one in red (it will be faster).

    Someone needs to build an adapter that connects to a PCIe x8 slot and has mounting points for up to 4 or 8 PCIe M2 SSDs.

    lots of empty space on that PCB and its only a half height card. Maybe its possible we can see multiple TB PCIs SSDs in the consumer space or they may just restrict it to enterprise.

    300 dollar for 256 gb... i can buy 4x 120gb v300 kingston (2200mb/s R) (1920mb/s W)
    raid 0. too expensive. that plextor

    Who keeps telling you there is no demand for M.2 drives?

    I bought a Lenovo Y410P shortly after they were released (and was incorrectly told it had mSATA not NGFF/M.2 for the SSD), and have been waiting over a year for a decent M.2 drive to put in it.

    May be in a few years we will see an ssd connected to a PCIe x16 the and size of a graphics card.

    How much does it add to boot-time with its bios loading stuff? Other PCI-e cards add as long as a 1-2 minutes to boot time.

    It's only a single AHCI device, and it doesn't have to wait for spinup like other raid controllers, so likely only a second or so extra init time.

    The drive itself has no wasted space. The bridge board has plenty, being that the drive is only 22mm x 80mm.

    It adds all of about a second. You'll never notice, and based on UEFI settings, you might never even see the Plextor op-rom splash screen at post.

    On the desktop, the demand for M.2 storage is not very high yet. In laptops, SATA M.2s are in high demand, but there isn't much reason to have a pure M.2 native PCIe Phy drive in a desktop yet. The M6e we looked at is built around the AIB bridge board, and thus isn't detachable from the M.2 drive itself, so despite the M.2 drive at the heart of the board, you still really can't buy a M.2 native PCIe drive yet. And even if you bought a M6e, ripped it out of the bridge board, and installed it in the Lenovo -- it probably wouldn't see more than a single lane of connectivity.

    Regards,
    Christopher Ryan

    Fun stuff here. Makes me interested what options I'll have to work with when I'm due for an upgrade in two years.

    Ill pick one up, alot of space on that card tho, why not put another set and make it a full sized card?

    If you remove the SSD drive from the PCI-e adapter board, will it work in the new Z97 motherboards, in the M.2 slot?
    BTW: I know it will void the warranty.

    I posted the same question in the forums, and got an answer: NO!

    If I wish to use a m.2 SSD, it looks like I'd have to get a Crucial M550 m.2 SATA SSD. No PCI-e SSD's available yet!

    EDIT: 06/11/2014 - BTW, YES it will work. Mine does! And it uses the 2 PCI-e channels. My Z97 mobo sees it with no problems! That's what I'm running now.

    I believe this type of product will kick the mSATA drives to the curb before these can become popular. Won't be the first time I've seen this, though. A technology released, then quickly superseded for another.

    Will be great to have these for notebooks, though an adapter will be needed for current releases, negating any performance gains. Because this option isn't dependent on, nor was designed for, a SATA 3 port. A true PCI-e port will be needed.

    Who said that the PC was dead, again? We have every reason to keep them very much alive.
