What it is
The Crucial M4 CT064M4SSD2 is a 64GB 2.5 inch internal solid state drive that uses a SATA III interface and MLC NAND flash. It is designed for consumer desktops and notebooks that need faster boot and application load times than a hard drive can deliver.
SATA III limits
On a SATA 6Gb/s port the drive reaches up to 500MB/s sequential read and 95MB/s sequential write; on a SATA 3Gb/s port sequential read drops to 265MB/s. Random performance is rated at 45,000 IOPS read and 20,000 IOPS write with an average access time below 0.1ms.
Build and connectors
The drive consumes less than 65mW idle and 0.15W active, and operates from 0°C to 70°C. Its 2.5 inch form factor fits standard drive bays and the SATA connectors provide broad compatibility with existing laptops, desktops and workstations.

Otázky k tomuto produktu
Should I pick the 64GB M4 or a larger capacity?
The 64GB model suits a boot drive with core apps; larger capacities in the M4 range give more room for media and games.
What does the 500MBps sequential read mean on my SATA 6Gb/s system?
On a SATA 6Gb/s port the drive can sustain up to 500MBps reads; on a 3Gb/s port it drops to 265MBps.
How does the SATA III interface limit real-world speed?
The SATA 6Gb/s link caps sequential transfers at roughly 500MBps read and 95MBps write for this drive.
