Solidigm D3-S4520 480GB SATA SSD

This 480GB enterprise solid-state drive uses the SATA III interface in an M.2 2280 form factor. It is built with 144L TLC 3D NAND for read-intensive workloads in servers and data centres. The drive suits operators who need standard endurance for cloud storage tiers rather than write-heavy applications.

Thermals noise and power in normal use

The drive operates between 0°C and 70°C with no moving parts, so it produces no acoustic noise. Sequential reads reach up to 550 MBps and writes up to 500 MBps within the SATA III bandwidth. Solid-state construction also means it tolerates 2.17 GRMS operating vibration without performance loss.

Behaviour under sustained load

A 2,000,000-hour MTBF rating reflects design for continuous operation in rack environments. The controller maintains throughput during extended reads while the SATA interface caps peak bandwidth. Shock resistance of 1,000 G at 0.5 msec protects data during handling, and non-operating vibration tolerance reaches 3.13 GRMS.

Questions about this item

How do I install the M.2 2280 SATA drive and what step is often missed?

Insert the M.2 2280 card into a SATA-keyed M.2 slot, secure it with the screw, then enable SATA mode in BIOS — many builders forget the BIOS step and the drive stays invisible.

What maintenance or replacement will the 144L TLC 3D NAND need later?

The 144L TLC 3D NAND has no user-serviceable parts; when the drive reaches its write endurance limit it is replaced as a whole unit.

At what point does the 0°C to 70°C operating range become the limiting factor under sustained use?

Continuous heavy writes can push the controller toward the 70°C ceiling; once that temperature is reached the drive throttles to protect the 144L TLC 3D NAND.
