Plextor M5 Pro review: Plextor M5 Pro

While the look and function of the Plextor M5 Pro are very similar to its peer, on the inside, the drive is quite different. It's the first drive I've seen that uses Marvell's 88SS9187 Monet controller, which supposedly provides enterprise-grade double data protection. It's hard to test this out, however, since it can only proved by using the drive over time but the drive is slated to offer more than 2.4 million hours of meantime between failure, about double that of others.

To prove its confidence in the new drive's longevity and reliability, Plextor gives it the top five-year warranty.  When it comes to storage devices, the warranty time is the most important and Plextor deliver in the case of the M5 Pro.

Performance
I am not sure about the Plextor M5 Pro's lifespan, which'd take more time than I can afford to test, but I was in impressed by the its performance. With just 11 seconds boot time and 6-second shutdown time, the drive will definitely bring a new life to a computer that's been running a hard drive as its main drive.

All applications also took much shorter time in my trials to load and the test computer resumed from sleep mode instantly. The drive also did very well in in sequential write and read performance test, where I measured how fast it can transfer a large amount of data.

When used as a secondary drive, where the Plextor could show its top performance since it only performed the writing, drive scored some 250MBps. When used as a host drive of a computer and did both writing and reading at the same time, it registered 156MBps. Both of these numbers were among the top three of all SSDs I've seen.
