The 128GB Crucial M4 is almost three years old, an extremely long time in SSD land. With peak and average sequential read/write speeds of 500/194 and 429/185 the 128GB M4 matches the group leaders at reading but lags by 60% at writing. Comparing the 128GB and 256GB versions of the M4 shows that the two drives have a very similar performance profile. This suggests that both drives have the same number of NAND channels which bodes well for the smaller capacity drive as a lot of other drives exhibit slower writes speeds in the smaller capacity varieties. Small file 4k peak and average read/write speeds measured at 27/87 and 21/52 MB/s which is only 13% below the average of the nine user voted group leaders. Considering its age the M4 is a very impressive drive but there is far better value for money available in today's market. [Feb '14 SSDrivePro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketing teams operate large numbers of reddit accounts. When UserBenchmark’s data contradicts their marketing spiel, they deflect by systematically attacking our reputation.
Why don’t large PC brands support UserBenchmark?
PC brands make a lot of their profit from flagship hardware sales: 4090, 14900KS, 7950X3D etc. We help consumers to choose hardware that offers similar real world performance at a fraction of the cost.
Why don’t any youtubers promote UserBenchmark?
We don't sponsor youtubers, so they have no incentive to make positive content about us. Additionally, the brands with weaker products tend to spend more on youtube marketing, which puts their youtubers at odds with UserBenchmark.
Why does UserBenchmark have so many negative trustpilot reviews?
Trustpilot hosts user-generated reviews in an online community that's open and accessible to all. Looking at its 200+ UserBenchmark reviews, which are mostly written by virgin accounts, it is glaringly obvious that they were created by a marketing team. Real users don’t have any time or interest to promote one brand over another.
Why is UserBenchmark so popular with users?
Instead of trying to win lucrative sponsorship deals with billion dollar PC brands, we have spent the last 13 years 100% focussed on providing comprehensive, accurate and relevant information for our users. As a result, most of our users return over and over again because collectively they save millions of dollars every year.
The Best.
