The Plextor M5 delivers fantastic value for money and sits within easy reach of the top handful of SSD's currently available. The M5's performance favours server type workloads where it takes joint fourth position in the AS-SSD total score benchmark. With a Real World Speed Index of 524.5 it will also cope very well with consumer workloads. Aside from its blistering performance we also like the fact that this drive uses the latest Marvell controller which hasn't suffered any of the reliability issues that plagued some of the early Sandforce based drives. When this drive first hit the shelves in September '12 it was overpriced but since then prices have dropped by nearly 40% making it currently one of top five value for money drives available. [Jun '13 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
