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?
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.
