HPE's Solid State Disk Drives QuickSpecs list P64844-B21 as the HPE 1.92TB NVMe Gen4 Mainstream Performance Read Intensive SFF BC U.3 Static V2 Multi Vendor SSD: a 2.5-inch hot-plug NVMe drive in a Basic Carrier (BC), single-port, TLC NAND, for Gen11 and Gen12 servers. PartSurfer maps it to spare P65193-001.
HPE rates it at 3,504 TB written (1.0 drive write per day), sequential reads and writes of up to 6,200 and 2,681 MiB/s, and maximum random 4KiB reads of 811,976 IOPS at queue depth 256. That is roughly seven times the sequential read rate HPE lists for its 12G SAS Value SAS drives.
Mainstream Performance is HPE's cost-focused NVMe tier, below the High Performance NVMe class; HPE describes it as advanced data center drives tuned for performance and endurance in a cost-effective design. Read Intensive (1 DWPD) suits boot, web, analytics and read-heavy virtual machine stores rather than write-heavy databases.
U.3 matters for fit: the drive needs a U.3 (TriMode) backplane, which HPE offers on Gen11 SFF cages such as the DL360 and DL380 Gen11 8SFF models, and the controller or direct-attach path must support NVMe. Multi Vendor means HPE ships drives from more than one maker under the number, with each order a homogeneous set from one vendor.
Siblings in the same line: P64842-B21 (960GB, 1,752 TB written) and P64846-B21 (3.84TB, 7,008 TB written, 3,969 MiB/s writes).
To confirm fit, check that the server's SFF bays have a U.3 x1 or x4 backplane and that NVMe is enabled for those bays.
