256 GB MLC SATA III SSD
The Crucial M4 CT256M4SSD1 is a 2.5 inch internal solid-state drive with 256 GB capacity and a 7 mm height. It uses MLC NAND and a Marvell controller on a SATA III interface. The drive targets consumer notebooks and desktops needing a slim profile without sacrificing storage space.
Sustained sequential performance
On a SATA 6 Gbps link the drive delivers up to 500 MBps sustained sequential read and up to 260 MBps sustained sequential write. On a SATA 3 Gbps link sustained sequential read reaches 265 MBps. Random performance reaches up to 45000 IOPS read and 50000 IOPS write at 4 KB.
SATA III interface limits
The SATA III interface caps theoretical throughput at 6 Gbps, so real-world sustained speeds cannot exceed the bus limit. The drive operates from 0 °C to 70 °C and draws less than 85 mW idle and 0.16 W active. MTBF is rated at 1200000 hours with built-in EDC and ECC for data reliability.

Domande su questo articolo
How much power does the 256GB M4 draw when active all day?
Active power is 0.16W; idle power is below 85 mW, so heat and noise stay minimal during continuous use.
What must my laptop or desktop already have to install this 2.5 inch SATA III drive?
A free 2.5 inch drive bay or caddy and a SATA data plus power connector; the drive is 7mm high and fits standard SATA III ports.
Will the M4 work reliably with an older SATA 3Gbps motherboard?
Yes — it runs at SATA 3Gbps with sequential reads up to 265MBps and writes up to 260MBps, and supports the SMART command set for monitoring.
