120GB SATA III MLC SSD

The Crucial M500 CT120M500SSD1 is a 2.5 inch internal solid state drive built for consumer desktops and laptops. It uses MLC NAND and a Marvell controller to deliver sequential reads up to 500MB/s and writes up to 130MB/s. Random performance reaches 62,000 read IOPS and 35,000 write IOPS. The drive is rated for 1,200,000 hours MTBF.

Fits standard 2.5 inch SATA bays

Installation requires a free 2.5 inch drive bay and a SATA data cable plus power from the system. The 7.00mm height matches typical laptop and desktop caddies. Replacing a mechanical disk removes rotational latency and frees up the SATA bus for quicker boot and application load times. No additional drivers are needed for native OS support.

Steady throughput under load

Sustained workloads stay within the 0°C to 70°C operating window without thermal throttling. The MLC memory and Marvell controller maintain consistent sequential and random speeds during extended file transfers or background indexing. MTBF of 1,200,000 hours reflects endurance for daily consumer workloads rather than burst-only benchmarks.

Questions about this item

At what temperature does the M500 120GB hit its operating ceiling during long workloads?

The drive is rated for continuous operation up to 70°C, so sustained heavy writes will be throttled once the controller reaches that limit.

How much power does the CT120M500SSD1 draw and how warm does it get when running all day?

As a SATA 2.5-inch SSD with no moving parts, it typically draws only a few watts and stays near ambient temperature inside a ventilated case.

Which SATA cable and power connector must already be in the system for this 2.5-inch drive to work?

A standard SATA III data cable and a 15-pin SATA power lead from the PSU are required; the drive uses the common 7.00mm height so it fits any 2.5-inch bay.
