Plextor M6M 128GB mSATA Solid State Drive Review
Chris Hadley / 6 months ago
A few months ago I took a look at a drive that has managed to slingshot Plextor right back into the enthusiast market with a drive that took the limitations of the SATA III interface and threw it out of the window, using the supreme bandwidth of a PCIe interface to allow it to stretch its legs out and give us some proper next generation performance. Now if you’ve not guessed which drive I’m on about here, I’m referring their M6e PCIe SSD – which uses the latest M.2 NGFF interface to deliver levels of performance that may have dreamed of for quite some time.
Whilst the M6e is a great product to behold, it is not for everybody. Firstly we have to look at the cost and with a 512GB drive fetching over £500 / $800, it is a heavy investment to made and secondly its compatibility list is somewhat limited, knocking many mATX builds and portable systems out of the question. Fortunately though Plextor were not naive enough to force users on to the M.2 platform to enjoy the performance that is on offer from the components of the M6e. Alongside the next generation drive, Plextor have brought two more drive to market that follow are more traditional approach to storage, using the most commonly used interface, SATA, and its compact alternative mSATA. Whilst both the mSATA and SATA drives are not able to offer the break neck speeds that can be achieved through a native M.2 or PCIe interface, they still play home to the same controller and NAND packages, just with a lower headlining above them.
The drive we’ve got to play around with today come in the mSATA form factor and with the M6M product name (the second M representing mSATA) we can easily point out its association with the highly popular M6e. Built around the same Marvell 88SS9188 controller and custom firmware, the M6M comes in capacities ranging from 64GB right up to 512GB, all within the same 50.8 x 29.8 container, allowing them to fit into virtually any device that houses a mSATA port. Offering sequential read and write speeds of up to 520MB/s and 440MB/s with IOPs ratings of up to 94K read and 80K write, the M6M is by no means a basic solution for mSATA devices – it is a workhorse that delivers just as much of a punch as its bigger brothers which are part of the SATA and M.2 groups.
Where most drives come in a sleek box with a colourful presentation on the front, the M6M uses packaging the like it’s from a value RAM production line. The only indication of which drive is enclosed is found on a single sticker attached to the front of the pack. At the bottom of the sticker we do get a short list of performance ratings so we at least know what type of performance we should be expecting once plugged in.
