Plextor M3 256GB SATA 6Gb/s Review – Another Win for The Marvell 9174 Controller

CRYSTAL DISK BENCHMARK VER 3.0.1 x64

Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. The Plextor M3 performs the same, regardless of the compressibility of the data.

The Crystal Disk Benchmark results are very good, with the low 4k read performance coming in around 33 MB/s. The high sequential reads of 526 MB/s are especially encouraging along with the low 4KQD32 performance of 300MB/s read.

AS SSD BENCHMARK VER 1.64

Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data. Many enthusiasts like to benchmark with AS SSD for their needs.

The access time of 0.038ms for read performance is simply outstanding. This is one of those times that when we run a benchmark, it’s time for a double take! There simply aren’t many drives out there that can match this score, and this is very relevant to normal users. This drive is visibly snappy and very fast in typical operating system usage, and this extremely low access time is the reason behind that.

One area where the Marvell equipped drives will really shine is with compressible data. The Plextor M3 performs very well with this benchmark, which contains incompressible data. SandForce drives would tend to turn up lower results with this type of data as data compression is a huge part of their performance advantage. The Plextor M3 simply excels regardless of the compressibility of the data that it is given to work with. For users who routinely work with data that is incompressible, or already compressed, the Plextor would be a great choice.

ANVIL STORAGE UTILITIES PROFESSIONAL

Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility.  Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.

We can observe some expected results here, with the 4k that is being recorded coming in a bit lower than observed with the other benchmarks. This is the purpose of running several different test scenarios, as there can be variations in performance recording.

    How does the M3 compare to the M2?

    • Support

      The M2 is 480/330 read/write and 15K/9K IOPS. The M3 is 510/360 read/write and 70K/65K IOPS. Also, the M2 comes bundled with the Acronis software where as the M3 is bundled with NTI Echo. Both drives have the same Marvell controller. However the M3 uses a Toshiba 24nm NAND as opposed to a Toshiba 32nm NAND found in the M2.

    whats the different between Plextor M3 and M3P ?

    • Support

      The M3P is essentially the M3S but with a different firmware which increases performance from 525/445 read/write to 535/450 and from 56K/30K IOPS to 56K/34K IOPS on the 512GB. Also, I believe the M3P is housed in a 7mm casing as opposed to a 9.5mm casing.

    If Marvell = faster latency but also lower bandwidth, does that mean if I’m RAID-0′ing 2 SSDs (for higher bandwidth speeds), I’d be better off with a Marvell controlled pair of SSDs rather than a pair of SandForce controlled ones?
