P50229-B21: HPE 3.2TB NVMe Gen4 High Performance Mixed Use SFF BC U.3 PM1735a SSD
Also listed as: P50966-001, P50228-001, MZQL23T2HCJR, MZQL23T2HCJR-00A07, SDFEC64HAE01 · made by Samsung
The HPE P50229-B21 is a 3.2TB NVMe PCIe Gen4 High Performance Mixed Use 2.5-inch SFF solid-state drive in an HPE Basic Carrier (BC). Powered by enterprise-grade Samsung PM1735a silicon, this U.3 drive provides 3 drive writes per day (DWPD) endurance, making it a staple for intensive virtualisation clusters, transactional SQL databases, and write-heavy workloads on HPE ProLiant Gen10 Plus and Gen11 servers. Used buyers must verify U.3 backplane capability, Tri-Mode cabling, and remaining write wear.

About the P50229-B21
The HPE P50229-B21 is an enterprise-tier 3.2TB U.3 NVMe PCIe Gen4 solid-state drive engineered for demanding mixed-workload data center environments. Packaged in HPE's Basic Carrier (BC) form factor for Gen10 Plus and Gen11 ProLiant platforms, it features a 3 DWPD (Drive Writes Per Day) endurance rating based on Samsung PM1735a hardware. This drive is positioned directly above read-intensive models to support OLTP databases, enterprise virtualization hosts, write-heavy caching tiers, and software-defined storage architectures.
Compatibility
The drive connects via the SFF-TA-1001 (U.3) standard and requires a compatible Gen10 Plus or Gen11 NVMe/Tri-Mode backplane linked to either direct-attach PCIe CPU lanes or an HPE Tri-Mode controller (such as the MR416i-p or MR416i-o Gen11). The Basic Carrier (BC) tray matches Gen10 Plus and Gen11 server bays; it does not seat into legacy Gen9 or standard Gen10 SmartCarrier (SC) backplanes without exchanging the carrier frame. U.2 backplanes without universal tri-mode routing pins cannot detect U.3 drives.
How to identify a genuine unit
Legitimate P50229-B21 drives are identified by an authentic HPE enterprise label with Option Part Number P50229-B21, Spare Part Number P50966-001, and Assembly Number P50228-001. The underlying hardware lists the Samsung enterprise model MZQL23T2HCJR. In iLO management interfaces and OS device managers, the drive reports HPE-customized NVMe firmware prefixed with HPDx or HPSx and serial identifiers that match physical chassis barcode tags.
Buying used
When evaluating used or off-lease P50229-B21 SSDs, query the NVMe SMART log for Percentage Used and Data Units Written to calculate remaining endurance against the 3.2TB 3 DWPD 5-year warrantied TBW pool. Ensure the carrier status indicator LEDs function correctly and check the drive connector pins for physical scoring or thermal discoloration. Confirm that the drive is not locked by a previously enabled HPE Smart Array or self-encrypting drive (SED) security password.
