HPE 791034-B21 1.8TB 10K-RPM SAS 12Gb/s SFF Hard Drive
The HPE 791034-B21 is a genuine 1.8TB SAS Enterprise hard drive built for enterprise storage environments where high capacity, performance, and uptime are critical. With an average seek time of just 3.7ms, it delivers fast data access for demanding workloads. The 12Gb/s SAS interface provides a stable, high-throughput connection with a data transfer rate of 1.2 GB/s, ensuring your most demanding applications never wait for storage.
This drive features dual-port SAS connectivity for built-in redundancy, boosting availability and fault tolerance in enterprise environments. It is also hot-swappable, meaning it can be replaced without shutting down the system — minimizing downtime during maintenance. The drive comes with an HPE Smart Carrier (SC) pre-attached, making it ready for hot-plug installation in compatible ProLiant and Synergy systems. The 512e Advanced Format ensures compatibility with both legacy 512-byte and modern 4KiB-aligned operating systems and applications.
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 server — mismatched or unverified parts can cause RAID rebuild failures or degraded performance.

FAQs
Why choose the HPE 791034-B21 over a smaller capacity 10K drive?
The HPE 791034-B21 offers 1.8TB of high-performance storage — significantly more capacity than typical 300GB-900GB 10K drives. This means you get more storage per drive slot without sacrificing the 10,000 RPM performance, making it ideal for virtualized environments and high-capacity database servers where space is at a premium.
Is the HPE 791034-B21 compatible with my Gen8 or Gen10 server?
Yes, this drive is fully validated for ProLiant Gen8 and Gen10 servers, as well as Gen9 servers. It is also compatible with Synergy 480/660 Gen9/Gen10 systems. However, this drive uses the newer Smart Carrier (SC) and is not recommended for G7 or earlier servers. Our free compatibility check confirms your specific server model and backplane revision before you order.
