High-capacity E1.S drive for read-heavy workloads

The Solidigm D5-P5430 delivers 15.36TB in a 9.5mm E1.S form factor using 192L QLC 3D NAND. It connects through a PCIe 4.0 x4 interface and is rated for up to 5900 MBps sequential read and 2300 MBps sequential write. Random read reaches 931500 IOPS at QD256 while random write hits 59000 IOPS. Endurance is rated at 0.51 DWPD or 14.43 PBW with a 2,000,000-hour MTBF.

Replaces lower-capacity

The jump makes sense when capacity per slot matters more than write endurance and the workload stays read-intensive. QLC density keeps acquisition cost per terabyte low, but sustained heavy write streams will wear the drive faster than TLC alternatives. Opal security is included for data-at-rest encryption without a separate controller.

Fits E1.S 9.5mm bays with PCIe 4.0 backplanes

Active power draw reaches 20W and idle drops to 5W, so the thermal budget must handle the peak. Operating temperature spans 0°C to 70°C with shock resistance of 1000 G at 0.5 msec and vibration tolerance of 2.17 GRMS operating and 3.13 GRMS non-operating. The drive weighs 66.5g and requires a compatible hot-plug cage or direct backplane slot.

Questions about this item

Will the E1.S 9.5mm form factor fit my server's drive bay?

The drive uses the E1.S 9.5mm form factor, so it requires a compatible E1.S slot with 9.5mm vertical clearance; verify your chassis or backplane supports this exact height before purchase.

What is the correct way to seat the PCIe 4.0 x4 connector during installation?

Align the edge connector with the PCIe 4.0 x4 slot and press firmly until the drive clicks into the latch; the common mistake is stopping at first resistance without engaging the retention mechanism.

How do I know when the 192L QLC 3D NAND is nearing its write endurance limit?

Monitor the SMART attributes for percentage of endurance used; the drive is rated for up to 0.51 DWPD or 14.43 PBW total bytes written, so plan replacement as that threshold approaches.
