1.92TB SATA enterprise SSD

The Solidigm D3-S4620 is a 1.92TB 2.5in SATA SSD built with 144L TLC 3D NAND for data-centre workloads. It delivers up to 550 MBps sequential read and 510 MBps sequential write with 91,000 random read IOPS and 53,000 random write IOPS. Endurance reaches 4.0 DWPD or 14.0 PBW with a 2,000,000-hour MTBF.

SATA III throughput ceiling

The SATA III interface caps sequential transfer at roughly 550 MBps read and 510 MBps write, so the drive cannot exceed those limits regardless of workload. Random performance tops out at the rated 91,000 read and 53,000 write IOPS. Active power draw is 3.3W and idle is 1.2W within a 0°C to 70°C operating range.

Check bay and controller support

Verify that your server or array accepts a 2.5in SATA drive and that the backplane or HBA provides a SATA III port. Confirm the chassis can handle the 62.6g weight and the rated 1,000 G shock and 2.17 GRMS operating vibration specs. Ensure the system firmware supports the advertised endurance and MTBF figures.

Questions about this item

Which capacity of the D3-S4620 should I pick for a read-heavy server workload?

The 1.92TB model delivers up to 550 MBps sequential read and 91,000 random read IOPS, giving strong read throughput for the capacity.

What does the 550 MBps sequential read figure mean once the drive is installed in a server?

It represents the peak sustained read speed over the SATA link; real-world throughput will be slightly lower due to protocol overhead and queue depth.

How does the SATA interface limit the D3-S4620 in practice?

The SATA III 6 Gb/s link caps maximum sequential transfer at roughly 550 MBps read and 510 MBps write, which this drive already reaches.
