The HPE P40506-B21 is a 960GB Value SAS 12Gb/s Read Intensive 2.5-inch SFF solid-state drive mounted in an HPE Basic Carrier (BC). Engineered for HPE ProLiant Gen10 Plus and Gen11 servers, Value SAS bridges the gap between enterprise SATA and high-performance dual-port SAS, delivering 12Gb/s single-port transfer rates and superior IOPS over SATA at competitive cost. Buyers of used units must verify the BC latch assembly and check wear endurance via HPE Smart Storage Administrator.

About the P40506-B21
The HPE P40506-B21 represents HPE's Value SAS solid-state storage offering, packaged in a 960GB capacity on a 2.5-inch Small Form Factor drive within the Gen10 Plus and Gen11 Basic Carrier. Value SAS utilizes a single-port 12Gb/s SAS physical interface to offer roughly twice the interface throughput of standard 6Gb/s enterprise SATA SSDs while retaining lower pricing than mission-critical dual-port SAS drives. It targets web serving, read caching, database read replicas, and boot/application tier workloads requiring 1 drive write per day endurance.
Compatibility
This drive requires an HPE server chassis equipped with Basic Carrier drive cages, natively standard on HPE ProLiant Gen10 Plus, Gen11, and Gen12 servers including DL380 Gen10 Plus/Gen11, DL360 Gen10 Plus/Gen11, DL385 Gen11, and DL325 Gen11. It is physically incompatible with legacy Gen8, Gen9, or standard Gen10 SmartCarrier backplanes without transferring the bare drive into a legacy SC caddy. In addition, an active SAS controller such as the MegaRAID MR416i or Smart Array SR controller is required, as standard SATA motherboard chipsets cannot communicate with SAS signal protocols.
How to identify a genuine unit
Genuine HPE P40506-B21 units feature an authentic HPE enterprise label displaying Option Part Number P40506-B21, Spare Part Number P41531-001, and Assembly Part Number P41101-001 or model string VO000960KZZTZ. Underneath the HPE branding, the drive chassis shows Kioxia OEM manufacturing markings (typically RM5 or RM6 series, model KRM6XRUG960G). In HPE iLO 5 or iLO 6 and HPE Smart Storage Administrator (SSA), genuine drives report digitally signed HPE firmware with an HPDx or HPSx revision prefix.
Buying used
When acquiring second-hand or refurbished P40506-B21 drives, inspect the HPE Smart Carrier / Basic Carrier status LED light pipe and front latch mechanism for physical integrity. Use HPE Smart Storage Administrator or standard smartctl utility tools to extract the Power-On Hours, Lifetime Remaining Percentage, and grown defect lists. Because read-intensive drives carry a 1 DWPD endurance rating, verify that cumulative terabytes written (TBW) reflect adequate remaining service life before redeployment.

FAQ
What is the difference between Value SAS and enterprise SATA in HPE servers?
Value SAS runs at 12Gb/s single-port interface speeds compared to 6Gb/s for SATA, providing significantly higher queue depths, lower command latency, and superior multi-threaded random read performance while maintaining price parity with SATA drives.
Can P40506-B21 work in a ProLiant DL380 Gen10 standard server?
The P40506-B21 comes in a Basic Carrier (BC) intended for Gen10 Plus and Gen11. Standard Gen10 servers use SmartCarrier (SC) trays, so you would need to swap the bare 2.5-inch drive into an SC tray (P/N 651687-001).
