About the P50227-B21
P50227-B21 is HPE's premium 1.6TB High Performance Mixed Use NVMe solid state drive built on the Samsung PM1735a platform and mounted in an HPE Basic Carrier (BC) U.3 tray. Operating over PCIe Gen4 x4, it combines Samsung's proven enterprise V-NAND architecture with HPE digitally signed firmware. Rated for 3 drive writes per day (DWPD), this model delivers exceptionally low write latency and consistent sustained IOPS under heavy multi-queue saturation, making it one of the most requested SSDs across secondary enterprise channels for Oracle, Microsoft SQL, and transactional caching nodes.
Compatibility
This drive is compatible with small form factor (SFF) drive bays in ProLiant Gen11 and Gen12 servers including the DL360 Gen11, DL380 Gen11, DL385 Gen11, and DL325 Gen11. The host bay must be wired to an NVMe backplane or connected via a tri-mode storage controller such as the MR416i-p or MR408i-o. Because it ships in the HPE Basic Carrier (BC), it will not lock into the Smart Carrier (SC) bays of ProLiant Gen10 or Gen9 servers. The retail order code is P50227-B21, while HPE service replacement units carry spare part number P51483-001 or P50227-001.
How to identify a genuine unit
An authentic P50227-B21 displays an HPE front label indicating the part number, spare number, and HPE firmware version, situated over the Samsung OEM factory label identifying model MZQL21T6HCJR. Inside iLO 6 under Storage, the drive reports as an authentic HPE NVMe SSD, displaying HPE-specific firmware versions (such as HPDx) and validated SPDM security certificates. Drives showing standard Samsung generic firmware (EDA7/EDA8) in iLO are retail units fitted into aftermarket caddies, which do not receive SPP updates.
Buying used
When purchasing used PM1735a drives, ask the seller for SMART attributes showing power-on hours, media wear indicators, and percentage used. The Samsung PM1735a controller offers exceptional durability, so units with under 20 percent lifetime consumption offer excellent longevity for enterprise production. Confirm that the drive is seated in an authentic HPE Basic Carrier with intact latch springs and proper light pipes, and ensure the gold edge fingers of the U.3 connector are free of gouges or carbon burns.
