Capacity and interface

The Solidigm D3-S4520 SSDSC2KB076TZ01 is a 7.68 TB enterprise SSD in a 2.5 inch form factor with a SATA III interface. It uses 144-layer TLC 3D NAND and is built for read-intensive data centre workloads. The drive suits operators who need high capacity on existing SATA infrastructure.

Upgrade path and value

It replaces mechanical hard drives in legacy servers to reduce operating costs while preserving the current backplane and cabling. The jump is worth it when read-heavy applications demand higher sequential bandwidth and lower latency than spinning media can deliver. The 4520 series targets read-intensive duties rather than write-heavy mixed workloads.

Sustained-load behaviour

Sequential reads reach up to 550 MB/s and writes up to 510 MB/s under continuous operation. The drive is rated for 2,000,000 hours MTBF and tolerates operating temperatures from 0 °C to 70 °C. Shock resistance is specified at 1,000 G for 0.5 ms and vibration at 2.17 GRMS across 5–700 Hz while running.

Points forts

  • High capacity of 7.68TB reduces server slot count
  • Sequential read speed up to 550 MB/s accelerates data access
  • Sequential write speed up to 510 MB/s handles intensive workloads
  • 2 million hours MTBF ensures long-term reliability
  • 144-layer TLC 3D NAND delivers power-efficient performance

Questions sur cet article

Does this 2.5 inch SATA drive fit a standard 2.5 inch hot-swap bay?

Yes. The 2.5 inch form factor matches standard enterprise drive bays and the SATA III interface uses the same data and power connectors as existing SATA drives.

What is the correct way to secure the drive in a server tray and the step installers often miss?

Slide the drive into the tray until the SATA connectors seat fully, then fasten the tray screws or tool-less latch; the missed step is not locking the latch or tightening the screws, which leaves the drive loose under vibration.

When will the 144 layer TLC NAND reach its write endurance limit under heavy write workloads?

The drive is rated for 2,000,000 hours MTBF; actual endurance depends on the write volume, but the 7.68 TB capacity and TLC design are built for read-intensive workloads rather than sustained heavy writes.
