Solidigm D7-P5520 1.92TB E1.S drive

The Solidigm D7-P5520 is a 1.92TB enterprise SSD built for data-centre servers. It uses an E1.S 9.5mm form factor and 144L TLC 3D NAND. The drive targets workloads that need high random-read performance and power-loss protection. Buyers needing a 2.5-inch or M.2 form factor should choose a different model.

PCIe 4.0 x4 interface limits

The drive connects through a PCI-Express 4.0 x4 link and reaches up to 5300 MBps sequential read and 1900 MBps sequential write. Random 4K performance is rated at 706000 IOPS read and 114000 IOPS write. A host slot limited to PCIe 3.0 will reduce these throughput figures. Endurance is 3.5 PBW with a 2,000,000-hour MTBF.

Check E1.S cage and power budget

Verify that your chassis accepts E1.S 9.5mm modules and provides the required PCIe 4.0 x4 wiring. Active power draw is 13W and idle power is 5W. The unit weighs 72g +/- 5g and tolerates 1,000 G shock at 0.5 msec plus 2.17 GRMS operating vibration. Opal security is supported for hardware encryption.

Questions about this item

Should I choose the 1.92TB E1.S 9.5mm model or look for a different capacity in the D7-P5520 range?

The 1.92TB capacity is the specific model listed here. If your workload needs more or less space, other D7-P5520 capacities exist but are not detailed in this listing.

What does the 5300 MBps sequential read figure mean for my server workload?

That is the maximum sequential read speed over PCIe 4.0 x4. Real-world throughput depends on queue depth, block size, CPU and thermal limits in your chassis.

How does the PCIe 4.0 x4 interface cap performance in practice?

PCIe 4.0 x4 provides the electrical lane width for the rated 5300 MBps read and 1900 MBps write. The drive cannot exceed the bandwidth of that link.
