Conclusion 
Average Bench 95.9%
Average Bench 83.8%

The Evo is remarkable in that, like the Sandisk Extreme II, it features a second level cache. For the 250 GB Evo this consists of a 3 GB Turbowrite cache (TWC) which is a block of high speed Flash Memory. When the TWC is exhausted write speeds drop by approximately 50% but that won't often happen under typical consumer workloads. In terms of raw performance, even with its cache, the Evo still isn't the fastest drive. With a real world speed index reading of 439 MB/s the EVO is however, within reach of the two speed leaders (Vector and 850 Pro). At a price point of $130 the Evo is around 30% cheaper making it the best value for money SSDs I have seen in 2014. Comparing the Evo and the Sandisk Ultra Plus shows that the Evo is the winner but the Sandisk may be a viable alternative thanks to its cache-free, and therefore more consistent performance during extended writes. [Aug '14 SSDrivePro]

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]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
