HPE P21465-B21 8TB 7.2K-RPM SATA 6Gb/s LFF Hard Drive
The HPE P21465-B21 is a genuine 8TB SATA Low Profile hard drive built for enterprise storage environments where capacity, reliability, and data integrity are absolutely critical. Spinning at 7,200 RPM with a drive transfer rate of 600 MBps (external), it is engineered to deliver high sustained throughput and dependable performance for backup, archival, and bulk storage workloads. The 6Gb/s SATA interface provides a stable, high-throughput connection, which is exactly what ProLiant Gen10 through Gen11 servers are built around.
What sets this drive apart is its 512e Advanced Format sector format for improved data integrity and broad compatibility with modern operating systems and applications. The drive features Digitally Signed (DS) firmware, which helps prevent unauthorized access to your data and protects against malicious attacks. It also supports Native Command Queuing (NCQ) for optimized performance in multi-drive environments. As a Business Critical class drive, it offers enterprise-class reliability for 24/7 data center operations. It comes with an HPE Low Profile Carrier (LPc) pre-attached, featuring a genuine HPE serial number and security sticker, making it ready for hot-plug installation in compatible ProLiant systems.
All HPE hard drives pass a rigorous qualification process, which certifies that every drive is proven to perform in your HPE ProLiant Server environments. Because this is a genuine HPE component rather than a generic or rebadged drive, it carries original HPE firmware and a genuine HPE security sticker. That matters when you're replacing a drive in a live production server — mismatched or unverified parts can cause RAID rebuild failures, performance degradation, or even system crashes.

FAQs
What is the difference between the P21465-B21 and the P21524-001?
The P21465-B21 is the option part number for the retail kit, while the P21524-001 is the spare part number used for field replacement and service orders. Both are the same physical drive: an 8TB 7.2K SATA 3.5" LFF Low Profile HDD with a Low Profile Carrier. For array expansion or retail purchase, the option part is typically the correct choice.
Is the HPE P21465-B21 compatible with my ProLiant Gen10 or Gen11 server?
Yes, the P21465-B21 is fully validated for ProLiant Gen10, Gen10 Plus, and Gen11 servers with 3.5" LFF drive bays, including DL360 Gen10, DL380 Gen10, ML350 Gen10, DL325 Gen11, DL380 Gen11, and ML350 Gen11 models. This drive uses a Low Profile Carrier (LPc), so it will only fit servers with LPc-compatible 3.5" LFF drive bays. Our free compatibility verification confirms your exact server model and backplane revision before shipping.
Can I order multiple HPE P21465-B21 drives for a spare pool or array expansion?
Yes. We stock bulk quantities of the P21465-B21 for data centers that keep warm spares on hand or are expanding storage arrays. Volume pricing is available, and we can pre-verify firmware across the entire batch so every drive is rebuild-ready. Contact us with your required quantity and server models for a quote.
