Review: Plextor M5 Pro Xtreme 512GB Reviewed by: Wendy Robertson Provided by: Plextor Model: PX-512M5Pro Firmware version: 1.02


Plextor has been causing quite a stir in the SSD market over the last couple of years. They have quietly been building their standing as a serious player in the SSD market. I believe this is largely due to their reputation for building solid and reliable SSDs, based on mature SSD controllers, and their own proprietary firmware. Not only that, but Plextor SSDs also perform extremely well.

The last time we reviewed a Plextor SSD here on Myce was back in March 2012, where we took a look at the 256GB M3 SSD. It was found to be a reliable SSD, and performed excellently. Today I'm taking a look at Plextor's latest and greatest consumer grade SSD in the shape of the new Plextor M5 Pro Xtreme 512GB SSD.

For the Plextor M5 Pro Xtreme, Plextor is still using a Marvell SSD controller, although the M5 Pro uses the newer 88SS9187 incarnation, with their own proprietary firmware, and Toshiba's new 19nm toggle 2 MLC NAND.

Just a couple of months ago, I looked at very similar hardware, in the shape of the Toshiba THNSNF512GCSS, although the hardware is comparable, Plextor use their own firmware, so let's find out how the Plextor M5 Pro Xtreme performs in this review.

In this article I will also be introducing a new test to our reviews here at (PC Mark Vantage HDD Suite), and I will also be introducing more in-depth queue depth profiling tests, which for the first time also build sequential reading and writing queue depth profiles. Lastly, but by no means least, I will also introduce comparison data for the ATTO benchmark, in the form of new comparison graphs for selected SSDs.      

Plextor company information

Plextor should need no introduction, but those of you who would like to find out more about Plextor, can do so at their website.

The Plextor M5 Pro Xtreme - 512GB SSD

Now it’s time to take a look at the drive itself and what it came shipped with.


The SSD I received was a retail unit, so let's first start with the packaging.

Box front

Box rear

Inside the box

The complete package

The Plextor M5 Pro package contained the Plextor M5 Pro Xtreme 512GB SSD itself, a 3.5 inch to 2.5 inch drive converter bracket, two packs of fixing screws, quick installation booklet, warranty information, and a serial key for NTI SSD Solution Suite.

Drive top

The top of the drive is made of metal, with a brushed aluminium finish, and looks very sleek.

Drive bottom

On the underside of the SSD, I found a label which displays the SSD model number, storage capacity, and indicating that the SSD was manufactured in January 2013.

The case itself is 7mm thick and designed to be housed in a standard 2.5 inch drive bay, or a 3.5 inch drive bay using the supplied converter bracket.

Now let's head to the next page, where we look in more detail at the Plextor M5 Pro SSD..... settings
