Plextor M5M mSATA SSD (128GB) - Small Wonder

Results - AS SSD Benchmark

AS SSD Benchmark

AS SSD is a benchmark that uses non-compressible and completely random data. What this means is that the drives using the SF-2281 controller cannot compress the data first, which takes away one of the strong advantages of this controller. Therefore this is a useful benchmark because drives that use the SF-2281 don't gain an upper hand.

Marvell-driven SSDs have traditionally performed well on this benchmark and the Plextor M5M didn’t disappoint. On the copy benchmark, it was easily quicker than Intel SSD 520 Series mSATA drive and was comparable to the rest of 2.5-inch form factor SandForce drives. Performance was also pretty comparable to the Plextor M5 Pro.

Performance on the rest of the benchmarks, particular sequential read/write and and 4k, 64 threads read/write was impressive, and the Plextor M5M was comfortably ahead of all the drives except the Plextor M5 Pro and Vertex 4.

The Good
Good performance on AS SSD and Iometer
High-end Marvell controller and NAND memory chips
Well priced
The Bad
Erratic performance on HD Tune, PCMark 7 and PCMark Vantage
