SATA III M.2 2280 512GB SSD

The SanDisk X400 SD8SN8U-512G-1122 is a 512GB internal solid state drive built for enterprise workloads. It uses a M.2 2280 form factor with a SATA III interface and sixth-generation TLC flash memory. Sequential reads reach up to 540 MBps and writes up to 520 MBps. The drive measures 1.5mm in height for slim system compatibility.

Enterprise workloads and thin systems

This drive suits users running heavy workloads such as photo and video editing, multitasking or office productivity in ultrathin designs. It offers endurance up to 320 TBW with nCache 2.0, DataGuard client and LDPC error correction for data integrity. Buyers needing a 2.5 inch 7mm drive should select that form factor instead.

SATA III interface

The single specification that decides fit is the SATA III interface, which limits throughput to the SATA bus rather than PCIe lanes. Verify the host system provides a SATA-wired M.2 slot before purchase. Operating temperature ranges from 0°C to 70°C with shock resistance rated at 1500G.

Questions about this item

Will the 1.5mm single-sided M.2 2280 module fit my laptop's M.2 slot?

Yes, the drive uses the standard M.2 2280 form factor with a 1.5mm single-sided profile, so it fits any M.2 2280 slot that accepts SATA signalling.

What is the correct way to secure the drive after inserting it into the M.2 slot?

Insert the drive at an angle, press it flat, and fasten the single retention screw; the step often missed is fully tightening that screw so the drive stays seated under vibration.

How many terabytes can be written before the TLC NAND reaches its rated endurance?

The drive is rated for up to 320 TBW, which represents the total host writes the TLC memory is warranted to sustain.
