About the 870753-B21
The HPE 870753-B21 is the 300GB capacity model in HPE's final 15,000 RPM enterprise SAS hard drive family. Spinning at 15,000 RPM with dual-port 12Gb/s SAS host interfaces, it delivered the lowest rotational latency achievable with magnetic media. It was commonly configured in mirrored pairs (RAID 1) as high-reliability server boot drives and dedicated transaction log volumes prior to the widespread adoption of SSDs.
Compatibility
Compatible with standard 2.5-inch SmartCarrier backplanes on HPE ProLiant Gen8, Gen9, and Gen10 servers, such as DL380 Gen9/Gen10, DL360 Gen9/Gen10, DL560 Gen10, and ML350 Gen10. It cannot be used in Gen10 Plus or Gen11 servers utilizing Basic Carrier (BC) cages without transferring the bare drive to a BC tray. Requires a 12G SAS RAID controller or HBA.
How to identify a genuine unit
Genuine units feature an HPE drive label indicating Option Part Number 870753-B21, Spare Part Number 870792-001, and Assembly Part Number EH000300JWHPS. The mechanical drive inside is a Seagate Enterprise Performance 15K drive (model ST300MP0006). In HPE SSA and iLO, the drive displays authentic HPE firmware prefixes.
Buying used
When buying used 15K RPM drives, check that the spindle motor reaches operational speed without stuttering or high-pitched grinding noises. Inspect SMART logs using smartctl to ensure zero Reallocated Sectors, zero Read/Write ECC uncorrectables, and verify that total Power-On Hours reflect realistic remaining operational life. Confirm that the SmartCarrier caddy latch and status LEDs function properly.
