This item, P70498-001, is the HPE spare part number for the product described as 6.4TB NVMe Gen4 High Performance Mixed Use SFF BC U.3 PS1030 SSD. Further details below.

The HPE 6.4TB NVMe Gen4 High Performance Mixed Use SFF BC U.3 PS1030 SSD (P70498-001) is a genuine HPE drive for mixed read and write workloads on PCIe Gen4 NVMe servers. It ships in the SFF (2.5-inch) form factor on an HPE Basic Carrier (BC) and is hot pluggable, so it can be added or replaced without taking the server down. HPE rates it at up to 7,066 MiB/s sequential read and 6,345 MiB/s sequential write, 251,921 random read and 732,734 random write IOPS at a queue depth of 16, and a peak of 903,765 random read IOPS.

Endurance is 3.43 Drive Writes Per Day with 40,062 TB of lifetime writes, which suits balanced read and write work such as databases, virtualization and transaction logging. It draws 4.23 W idle and 20.31 W at most, in a 15 mm package. The firmware is digitally signed and HPE lists the drive for Gen11 and Gen12 platforms; the 23 ProLiant models in the Compatible With section below carry it in their QuickSpecs. Every part ships tested or factory sealed and is backed by a 3-year replacement warranty.
