960GB SATA enterprise SSD

The Solidigm D3-S4520 is a 2.5-inch solid-state drive built for server and data-centre workloads. It uses 144L TLC 3D NAND and a SATA III interface to deliver up to 550 MBps sequential read and 510 MBps sequential write speeds. Random performance reaches 90,000 IOPS read and 43,000 IOPS write. Endurance is rated at 3.0 DWPD or 5.3 PBW with a 2,000,000-hour MTBF.

Suited for read-intensive arrays.

This drive fits read-intensive applications such as boot volumes, content delivery and warm data tiers where the 3.0 DWPD endurance budget matches the workload. Buyers who need higher write endurance for logging, caching or database journals should look at drives with a larger DWPD rating. Systems limited to SATA II ports will not reach the quoted throughput.

3.0 DWPD endurance decides fit

The 3.0 drive writes per day rating over five years translates to 5.3 PBW total bytes written. That single figure determines whether the SSD can sustain your daily write volume without exceeding its warranty lifetime. Compare your application's average daily writes against this number before purchasing.

Questions about this item

How can I verify the D3-S4520 960GB is performing correctly after installation?

Run a benchmark and confirm sequential reads near 550 MBps, sequential writes near 510 MBps, random reads near 90,000 IOPS and random writes near 43,000 IOPS.

What ships with the SSDSC2KB960GZ1Z and what must I source separately?

The drive itself is supplied in a generic single pack; a 2.5" SATA data cable, power cable and any mounting bracket are not included.

Which capacity of the D3-S4520 series should I choose for a write-heavy workload?

The 960GB model delivers up to 3.0 DWPD and 5.3 PBW endurance using 144L TLC 3D NAND.
