Crucial claims the m4 can achieve read speeds of up to 415MB/s, which is 17% higher than the C300's quoted figures. Write speeds vary between models with the 64GB iteration starting at 95MB/s, followed by the 128GB at 175MB/s, while the 256GB and 512GB versions tout a write throughput of 260MB/s. Compared to the C300, the m4's write speeds are faster by 27%, 25% and 20%, respectively.
Crucial's new drive utilizes the Marvell 88SS9174 controller along with a large Micron 256MB cache to improve small write performance and eliminate any 'stuttering' issues.
The m4's flash NAND memory is made by Micron, and feature Micron's high-speed ONFI 2.1 NAND interface for 166 MT/s with 512-byte industry standard sector size.
Crucial says its m4 series has a MTBF of 1.2 million hours, which is somewhat more conservative of an estimate than the ~1.5 million hours you'll find on most other SSDs. To accompany the usual MTBF figure, Crucial also provides a drive endurance rating for each model.
Like all SSDs, the m4 cites very low power consumption figures. At idle, all four models use less than 100mW. When active, the 64GB and 128GB versions consume just 150mW, while the 256GB and 512GB models have a rating of 160mW and 280mW - the latter of which is still exceptionally low. Read more...
