The Crucial M4 is one of the oldest SSD's to have made it into the group test. When it was released its primary competitors were Sandforce based drives which suffered from two major problems: reliability and weak incompressible data performance. As a result this drive was one of the top drives of its time. That was back in Apr '11. Today the M4 is no longer able to compete and scores below average (377.9 MB/s) on the Real World Speed Index benchmark and way below average (676) on the deep queue depth orientated AS-SSD Total score benchmark. Of course these figures are still far faster than any mechanical hard drive and owners of this drive should feel in no hurry to upgrade. People looking to make a new purchase will find much better value elsewhere. [Apr '13 SSDrivePro]

MORE DETAILS

We had high expectations for the Crucial M500. Crucial have a long history of producing outstanding Solid State drives. Both the RealSSD 300 and the M4, three and two years old, were almost legendary in terms of reliability and performance. The M500 falls far short of our expectations. The drive is relatively cheap and as such we were expecting to compromise on performance but the M500 just falls too far short. With a Real World Performance of 377.5 MBps which is in the bottom 40% and an AS-SSD score of 901 points (50th percentile) the M500 demonstrates relatively weak real world and average server performance. The M500 is competing with the Sandisk Ultra which manages to squeeze out significantly more performance despite sitting in the same price bracket. [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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
