Plextor M3P 256GB SATA 3 SSD Review – Absolutely Marvell-ous Performance

Today we are going to be reporting on the Plextor M3P 256GB SATA 3 SSD. Pairing Marvell’s venerable 88SS9174 controller with the latest Toshiba 24nm Toggle Mode NAND, the Pro is not much different from the Plextor M3 SSD that we reviewed a short time ago.

Aside from the new thinner 7mm chassis, the only difference you’ll find between the regular M3 Standard and the M3 Pro is the custom Plextor firmware being employed. That might just be enough to put it over the top.

INTRODUCTION

Plextor’s M3 “Standard” isn’t being replaced by the M3 Pro, but rather, The M3 Pro is being offered as a higher performing option alongside the regular M3. In examining the M3 SSD last month, we found it to be one of the faster drives on the market, eclipsed only by the fastest SandForce-powered offerings.

The M3 Pro doesn’t fix what isn’t broken, and instead takes the same Marvell controller and same fast Toshiba Toggle flash and lays it in a 7mm metal chassis. The cherry on top is the new firmware which promises higher sequential and random numbers than the M3.

If you could find the M3P on store shelves, it would be hard to miss with it’s high gloss metallic blue box. Inside the box, you’ll find the M3P SSD, a 3.5″ adapter sled, a quick start and warranty leaflet, and a software disk.

Depending on what region of the world you’re buying the M3P in, you could get drive cloning software different from the included NTI Echo. Echo has one helpful feature which allows the user to exclude folders from the source drive when cloning. This is useful if you happen to have 600GB of video on a hard drive that  you don’t want to include when cloning to a smaller SSD. Also included on the disk is additional backup software and a SSD Performance Analyzer.

SPECIFICATIONS AND PRICING

The rated specifications of the Plextor PX-M3 Pro 256GB SSD are substantial. Sequential reads and writes are listed at 540MB/s and 420MB/s, respectively. Random performance is rated at 75,000 4K read IOPS and 68,000 4K write IOPS. The 256GB also has 512GB of DDR3 cache onboard, like the M3S before it, and Plextor’s 5 year warranty is also extended to the M3P as well, putting it in rather rare company these days. The M3 Pro family is available in 128GB, 256GB, and 512GB capacities and a quick check shows prices of $204, $374 and $679 respectively.

INTERIOR COMPONENTS

Cracking the M3 Pro open reveals a familiar sight. Eight Toshiba TH58TEG8D2HBA8C NAND packages are present on the front of the PCB. Each package is composed of 8x32gbit (4GB) dice for a total capacity of 32GB per chip. Also strapped to the front are the two Nanya DDR3 1333MHz modules, each with a capacity of 256MB. The 128GB M3P also possesses two modules, but is only using 256MB. User capacity after formatting is 238GB.

On the back of the PCB, we see the Marvell 88SS9174-BLD2 controller which is also used in the Crucial M4. The old Plextor M2P/Corsair Performance Pro and Intel 510 use the ‘9174-BKK2 variant.

Like many of today’s SSDs, the M3 Pro is using thermal pads to conduct heat away from PCB components and into the chassis.

This is probably not a bad idea, but the residue left behind makes the NAND chips and other surface components look terrible in pictures.

    The Plextor M3P has new Firmware 1.03.

    Why was this not used in your testing? I see version 1.00 was used.

    The M3S aka M3 also has new Firmware 1.04 or 1.03 depending on the drive size.

    • http://www.thessdreview.com Les@TheSSDReview

      The M3P did very well and was reviewed as received… We will take a look at it with the new firmware and post back if any significant improvements are observed.

      • Christopher Ryan

        There are no observable performance differences between 1.00, 1.01, and 1.03.

        The benches do not reflect this, but the drive was upgraded and more tests were run.

  • observer

    with the 24nm process, shouldn’t it be 4x64gbit dies per package?

    • Christopher Ryan

      Most Toggle NAND drives use 32gbit dice, even at 2xnm design rules.

  • renosablast

    Makes one wonder if they could just get their hands on a regular M3 and update the firmware to the newest M3P version if they would get the same performance as the M3P?

    nope won’t work its been tried

  • Valentin Ursache

    i would like to know a comparison between OWC Mercury Accelsior 480GB PCIe SSD and two plextor m3 pro in the same raid 0…i have to choose between this two for my machine, especialy to see the numbers of incompressible data if it’s higher for the 2 plextor in raid 0 than owc’ card

      On Newegg in Canada, I read this comment about the Plextor M3P 256GB:

      Just received my 2nd Plextor M3 Pro 256GB for some Raid 0 action
      SMOKIN FAST, Installs flawlessly , no Faster sata III SSD on the market
      Everything you need but a SATA Cable comes with mounting plate , screws, software, broke 1004 Reads in CrystalDisk mark just google my nickname for more results. or AMD_Freak
