About the P40503-B21

The HPE P40503-B21 is the 960GB capacity entry in HPE's Multi Vendor SATA Mixed Use solid-state portfolio. Featuring a 3.0 Drive Writes Per Day (DWPD) endurance profile over 5 years, it is engineered for workloads with heavy write mixes that would prematurely exhaust standard read-intensive SSDs. It balances high capacity with enterprise endurance for transactional databases, mid-tier virtualization hosts, and software-defined storage journals.

Compatibility

Compatible with standard 2.5-inch SFF hot-plug bays in HPE ProLiant Gen10 Plus, Gen11, and Gen12 servers (such as DL380, DL360, DL385, and DL325) using Basic Carrier (BC) backplanes. It cannot be used in Gen8, Gen9, or standard Gen10 SmartCarrier (SC) backplanes without changing the drive caddy. Operates with onboard SATA controllers as well as HPE Smart Array and MegaRAID controllers.

How to identify a genuine unit

Genuine units feature an authentic HPE label showing Option Part Number P40503-B21, Spare Part Number P41528-001, and Assembly Part Number P41088-001 or model string VK000960GZXVS. The internal drive mechanism is built on Samsung PM897 (model MZ7L2960HCJR) or Micron enterprise flash. In HPE iLO 5/6 and SSA, the drive displays HPE digitally signed firmware with an HPDx prefix.

Buying used

When evaluating used Mixed Use SSDs, check the SMART attribute for SSD Wear Indicator and Total Written Terabytes. Because P40503-B21 carries a 3.0 DWPD rating (approximately 5.2 PBW), even off-lease units frequently retain substantial remaining operational life. Confirm that the Basic Carrier latch mechanism is unbroken and latches smoothly into server cages.

FAQ

What is the difference between P40498-B21 and P40503-B21?

Both are 960GB SATA drives, but P40498-B21 is Read Intensive (0.8 DWPD), whereas P40503-B21 is Mixed Use (3.0 DWPD), designed for write-heavy database and caching workloads.

Can P40503-B21 be used in a DL380 Gen10 server?

Standard DL380 Gen10 servers use SmartCarrier (SC) trays, whereas P40503-B21 comes in a Basic Carrier (BC). To use it in Gen10, swap the bare drive into a SmartCarrier caddy.
