Solidigm D5-P5430 15.36TB E1.S SSD

This Solidigm enterprise SSD delivers 15.36TB of storage in an E1.S 9.5mm form factor using 192L QLC 3D NAND. It is built for read-intensive data centre workloads where high capacity and power efficiency matter more than write endurance. The PCIe 4.0 x4 interface supports sequential reads up to 5900 MBps and random reads of 931500 IOPS at QD256.

PCIe 4.0 interface limits for write workloads

The drive reaches 5900 MBps sequential read but only 2300 MBps sequential write, while random write IOPS is 59000 at QD256. Endurance is rated at 0.51 DWPD over 14.43 PBW, so sustained heavy write streams will exhaust the warranty budget quickly. Active power draws 20W and idle power 5W, which is typical for the interface generation.

0.51 DWPD endurance decides fit

A single endurance figure of 0.51 DWPD (8K RW) determines whether this drive suits your workload. It fits read-heavy caching, content delivery or warm storage tiers, but it is not for write-heavy databases, logging or OLTP volumes that exceed the 14.43 PBW lifetime budget. Builders who need higher write durability should select a drive with a larger DWPD rating.

Questions about this item

Should I pick the 15.36TB E1.S 9.5mm version or a smaller capacity for my read-heavy server workload?

The 15.36TB model delivers up to 5900 MBps sequential read and 931500 IOPS random read, making it ideal for read-intensive applications that need maximum capacity in the E1.S 9.5mm form factor.

What does the 5900 MBps sequential read figure mean once the drive is installed in a live server?

In a PCIe 4.0 x4 slot the drive can sustain up to 5900 MBps for large-block reads, though actual throughput depends on the platform, queue depth and workload mix.

How does the PCIe 4.0 interface cap performance in practice?

PCIe 4.0 x4 limits the drive to a theoretical 8 GBps ceiling; the D5-P5430 reaches 5900 MBps read and 2300 MBps write, leaving headroom for protocol overhead and mixed I/O.
