Introduction

Plextor is not a name that you would have immediately associate with SSD manufacture – they’re probably best known to old timers as a leading manufacturer of CD/DVD drives – but they’ve been in the business a while. Unlike Intel or Samsung who have made their mark with their own brand controllers and software, Plextor has opted to go for a third party Marvell controller. These controllers are used to great effect in the popular Crucial M4, but require some special firmware to really unlock their potential.

Thankfully, Plextor have opted to do just that and their earlier M3 series SSDs were some of the fastest available. With the M3 Pro, they look to offer a premium option that promises even greater performance. Let’s find out if they’re able to deliver on their word.

Packaging

The M3 Pro comes in a light and unassuming blue cardboard box. On the front, you’ll see the drive pictured and titled, as well as other immediately important information like the capacity and included extras.

On the back there are some drier specifications in the requisite European and East Asian languages, as well as some exciting performance numbers – up to 535 MB/s sequential read and 350 MB/s sequential write.

Slide out the inner compartment and unfold it like a book, and you’ll see the drive ensconced in an anti-static bag and its optional 3.5″ adapter bay. There’s also a driver CD inside on the left hand side, a short manual  and that’s about it. It’s a very neat and tidy package, and I do particularly like the protection imparted by keeping the drive inside its adapter bay.

The SSD

The Plextor M3 Pro is a good looking and very thin drive, designed to be used in Ultrabooks where space is at an absolute premium. The drive measures 7 mm tall and comes in a cool grey colour. The bottom of the drive has a sticker with various digits including the model number (PX-128M3P), input voltage (5V @ 1.0A), date of manufacture (in our case, March 2012) and firmware (1.0).

If we were able to take the top off the drive, you could see the fairly straight-forward layout – the Marvell 88SS9174-BLD controller chip, SATA interface and 128 GB of Japanese NAND memory. Let’s move onto the fun part – benchmarking and testing!
