Average Bench: 78.3% (271st of 921)

Based on 1,855 user benchmarks.  Models: PLEXTOR PX-128M5Pro, PLEXTOR PX-128M5P

The 128GB Plextor M5 Pro has a reasonable performance profile. With an effective speed of 442 MB/s it ranks just 5% below the average of the top ten user rated 128GB SSDs, a good result. The M5 Pro's server orientated deep queue read/write speeds clocked in at 345/282 MB/s, slightly above average. As a consequence of having fewer NAND modules, the 128GB version is around 40% slower at sequential writing than its 256GB sibling. The larger capacity M5 Pro represents significantly better value for money. In the 128GB category some manufacturers (Samsung/OCZ) are offering the same sorts of speeds as typically seen in the faster 256GB category. In terms of performance, those SSDs currently stand heads and shoulders above the rest of the 128GB pack. There are several better value for money alternatives to the 128GB M5 Pro in the group test[Feb '14 SSDrivePro]
