Reviews
PC Advisor
We haven’t seen any SSD with the Crucial M4’s terrific sequential speeds… The M4 takes the crown as the best SSD we’ve seen. It comes highly recommended, especially given its lower price.
Computer Shopper
If you need an SSD now and you have a SATA3-equipped PC, the M4 is the best you can get.
Hexus.net
Crucial hasn’t reinvented the wheel, but by tweaking a tried-and-trusted controller it has produced an excellent SSD that’s both faster and cheaper than last year’s model. At this price, the m4 SSD is well worthy of consideration for any SATA 6Gbps system.
Bit-tech.net
The M4’s write speeds in ATTO were noticeably quicker than those of the C300 256GB, with a 4KB sequential write speed of 230MB/sec to the C300 256GB’s 188MB/sec. As the majority of writes on a consumer PC are 4KB, this bodes well for real-world performance.
