Purpose-built upgrade

The Crucial M500 is a 240GB internal solid-state drive built for consumer laptops and small-form-factor desktops that accept a Mini-SATA module. It uses MLC memory and a Marvell controller to deliver sequential reads up to 500MB/s and writes up to 250MB/s over the SATA interface.

Sustained workload behaviour

Random read performance reaches 72000 IOPS while random write hits 60000 IOPS, giving consistent responsiveness during multitasking and heavy file operations. The drive is rated for an MTBF of 1200000 hours and operates reliably between 0°C and 70°C.

Compatibility check

Verify that your system provides an mSATA slot and that the 3.75mm module height fits the available space. Confirm the platform supports SATA signalling on that connector before ordering.

Questions about this item

Does the mSATA M500 run hot or draw much power during all-day use?

The drive operates within a 0°C to 70°C range and has no moving parts, so it stays cool and silent under continuous load.

What does my laptop or motherboard need to accept this CT240M500SSD3?

A free mSATA slot with SATA signalling and a 3.75 mm clearance for the module height.

Will this 240GB M500 work alongside an older mechanical hard drive in the same machine?

Yes, it connects over standard SATA so the OS can boot from the SSD while the hard drive handles bulk storage.
