E1.S 9.5mm 3.84TB enterprise drive

This Solidigm D7-P5520 SSD delivers 3.84TB of storage in the E1.S 9.5mm form factor built for dense server chassis. It uses 144L TLC 3D NAND over a PCI-Express 4.0 x4 interface. Sequential reads reach 6500 MBps and writes reach 3400 MBps. Random read performance is rated at 1000000 IOPS with random writes at 147000 IOPS.

Read-intensive data-centre workloads

The drive suits read-heavy applications such as content delivery, web hosting and analytics where endurance of 7.0 PBW and an MTBF of 2000000 hours match the duty cycle. Active power draw is 15W and idle power is 5W. It is not suited for write-intensive logging or database workloads that exceed the rated endurance. Buyers needing a different form factor or higher write endurance should evaluate other models.

7.0 PBW endurance rating

The 7.0 PBW figure is the single specification that determines whether this drive meets a given workload's write demands. Compare the expected daily writes against this endurance budget before deployment. The drive weighs 72g and tolerates 1000 G shock at 0.5 msec. Vibration ratings are 2.17 GRMS operating and 3.13 GRMS non-operating.

Questions about this item

How does the 6500 MBps sequential read speed translate inside a live server?

The drive can sustain up to 6500 MBps reads over PCIe 4.0 x4, so large-block workloads such as log ingestion or media streaming hit that ceiling when the host and backplane also run at 4.0 speeds.

What does the PCIe 4.0 x4 interface limit in everyday use?

The four-lane 4.0 link caps theoretical throughput at roughly 8 GBps, so the 6500 MBps read and 3400 MBps write figures are the practical maximums you will observe.

Will the E1.S 9.5mm form factor fit my existing drive cage?

The module measures to the E1.S 9.5mm specification and weighs 72g, so it slots directly into any compliant E1.S hot-plug cage without adapters.
