PX M2

The M2 series of solid state drives from Plextor are one of the first SSDs to use the SATA III 6 Gbps interface.  This drive comes in three variants, namely 64 GB, 128 GB and 256 GB. Powered by a Marvell’s 88SS9174 controller, the M2 SSD has the ability to reach a maximum sequential read speed of 480 MB/s and a sequential write speed of 330 MB/s. IOPS numbers meanwhile includes a 15,000 4k random read and a 9,000 4k random write.

The M2 SSD has a Mean Time Between Failure (MTBF) of 1,500,000 hours and a warranty of three years. Inside the drive is a 128 MB DDR3 Cache for reducing the possibility of often-modified data from entering the flash memory system which may cause degradation of drive performance. Dynamic wear leveling technology is present which also expands the life of the drive further.

Plextor’s M2 SSD has a wide support for commands including TRIM, SMART, NCQ and ATA/ATAPI-8. This drive is one of the lowest power consuming drive as it only uses 0.25 W when idle and 0.75 W when active. The M2 can withstand a force of 1500 G and vibrations of 2.17G RMS.

The Plextor PX-M2 SSD fills an interesting space – kind of a SATA 6Gb/s mainstream/performance drive, if that makes sense. It won’t hang with the new generation of SandForce drives, but it won’t cost as much either, filling the need for those who want the benefits of SATA 6Gb/s throughput, but don’t need the interface saturating performance or cost. In the end, we’re pretty happy with Plextor’s second SSD effort and for a street price of $279, it looks like a good value too.

tweaktown:

Despite the Vertex 3 raining on Plextor’s best offering, to date we still see the Plextor M2 as having a place in the market. Power users looking to take performance to the next level with extravagant RAID arrays can rejoice in not needing to do regular spring cleaning, running the drives through HDDErase to regain performance. The Plextor M2 will also do very well in situations where TRIM is not available; legacy OSes like Vista, XP and MAC are prime targets.

legitreviews:

While the Plextor M2 Series puts up some nice performance numbers and offers the SATA 6Gbps interface, consumers will likely gravitate towards the newest SandForce controlled drives simply due to their sheer speed advantage.
