HPE 960GB SAS 12G Read Intensive SFF BC Value SAS Multi Vendor SSD (P40506-B21)

HPE's Solid State Disk Drives QuickSpecs list P40506-B21 as the HPE 960GB SAS 12G Read Intensive SFF BC Value SAS Multi Vendor SSD, the smallest drive in HPE's Value SAS Read Intensive Basic Carrier line, for Gen10 Plus and Gen11 servers. PartSurfer maps it to spare P41531-001.

HPE rates it at 1,700 TB written, or 1.0 drive write per day, with sequential reads and writes of up to 820 and 650 MiB/s and random 4KiB performance of 105,000 read and 41,000 write IOPS. It is single-port SAS on TLC NAND in a 2.5-inch hot-plug Basic Carrier.

At 960GB it fits operating system mirrors, hypervisor boot volumes and small read-heavy data sets on servers whose controllers already run SAS. HPE positions Value SAS between SATA and full-performance SAS: roughly twice the IOPS of SATA SSDs at a typically lower cost than dual-port SAS drives. Compared with the 1.92TB P40507-B21 in the same line, the 960GB drive has half the capacity and half the rated write endurance with similar speeds, so the choice is about capacity.

For more write endurance at the same size, the 960GB Value SAS Mixed Use BC drive is P40510-B21 (5,200 TB written, 3 DWPD). For dual-port operation, HPE's 24G SAS Read Intensive 960GB drive is P49029-B21.

Multi Vendor means HPE may ship SSDs from several makers under this number, with each order a homogeneous set from one vendor.

To confirm fit, check that the server's SFF bays take Basic Carrier drives and that the controller supports 12G SAS, and match P41531-001 when replacing a failed drive.
