Solidigm D7-P5810 High-Endurance SSD
Solidigm D7-P5810 is a small-capacity, ultra-endurance PCIe 4.0 NVMe SSD using SLC 3D NAND. Its purpose is sustained writing, low-latency cache and metadata work rather than bulk storage.
The published 800GB configuration reaches 50 DWPD and 73PBW over five years, a fundamentally different design point from high-capacity QLC SSDs.

What makes P5810 different
SLC stores one bit per NAND cell and gives up density to gain endurance and predictable write behavior. That makes P5810 much smaller and usually more expensive per terabyte than TLC or QLC enterprise drives.
Its value should be measured per required write and by service behavior under sustained load, not by raw capacity economics.
Write-intensive roles
P5810 can serve as a write-back cache, database journal, logging tier, metadata device or high-churn buffer in front of denser storage. It can also isolate write amplification from QLC capacity drives.
Capacity remains a hard constraint. If the active write set exceeds the available P5810 footprint, PS1030 provides a larger 3 DWPD tier, while software architecture may be needed to separate hot and cold data.
Qualification and alternatives
Confirm U.2 bay support, PCIe 4.0 x4 wiring, power-loss protection expectations, thermal limits and firmware qualification. A cache or journal device can become infrastructure-critical, so redundancy and spare strategy matter despite its small capacity.
Choose PS1030 when 3 DWPD is enough and more capacity is required. Choose PS1010 for read-intensive Gen5 performance, or P5336/P5430 when the real requirement is density rather than write endurance.
Frequently asked questions
What NAND does P5810 use?
Solidigm identifies D7-P5810 as an SLC 3D NAND enterprise SSD.
What is P5810 endurance?
The published 800GB specification reaches 50 DWPD and 73PBW over five years.
Is P5810 a good bulk-storage SSD?
No. Its strength is write endurance, while its capacity is small relative to enterprise TLC and QLC drives.
