Refurbished 512 GB SATA SSD for consumer laptops

This manufacturer-recertified Crucial M4 drive brings 512 GB of MLC storage to thin laptops and desktops that use a 2.5 inch SATA bay. The 7 mm height fits modern ultraportables without adapters. Sequential reads reach 500 MBps and writes reach 260 MBps on a SATA III link. Random performance hits 45000 read IOPS and 50000 write IOPS.

Solid build with standard SATA connectors

The drive uses a single Marvell controller with eight channels and includes SMART monitoring, EDC/ECC error correction and RAID support. Idle power stays below 100 mW and active power is 0.28 W. Operating temperature spans 0°C to 70°C while storage tolerance reaches -40°C to 85°C. MTBF is rated at 1200000 hours. The SATA data and power connectors are the same ones found on any 2.5 inch drive.

Check your system before ordering

Verify the machine has a free 2.5 inch bay that accepts a 7 mm drive and a SATA III port for full speed. Confirm the BIOS or UEFI recognises SATA SSDs and that no hardware RAID controller blocks the device. Ensure the operating system supports TRIM or an equivalent maintenance command for sustained performance.

Questions about this item

What speed does the SATA III interface limit this CT512M4SSD1 to in practice?

The SATA III link caps sequential throughput at 6 Gbps, so the drive delivers up to 500MBps reads and 260MBps writes in sustained transfers.

What physical space does the 7mm 2.5-inch CT512M4SSD1 need to fit?

It fits any standard 2.5-inch drive bay or caddy that accepts a 7mm height; the drive itself is 7mm thick.

How is the CT512M4SSD1 installed and what step do people often miss?

Connect the SATA data and power cables, secure the drive in the bay, then initialise and format the new volume in the operating system before use.
