300 GB SAS enterprise drive
This 300 GB internal hard drive uses a SAS 6Gb/s interface and spins at 15000 RPM. The 2.5 inch form factor fits standard SFF server bays and supports hot-plug installation. It is designed for enterprise servers that require consistent transaction throughput. The drive targets IT administrators managing high-I/O workloads in 24/7 data-centre environments.
Thermals noise and power in server use
The 15000 RPM spindle speed produces higher heat output and audible noise than lower-speed drives, so adequate chassis airflow is required. Power draw rises during sustained random I/O typical of database or virtualisation workloads. The SAS interface maintains stable performance under continuous duty cycles. Operators should plan cooling and power budgets for arrays of these drives.
Hot-plug carrier and warranty coverage
The drive ships in an HP hot-plug carrier that enables tool-less insertion and removal from compatible server backplanes. This reduces service time during drive replacement without powering down the host. A three-year manufacturer warranty covers the drive under normal enterprise operating conditions. Retail or OEM packaging may vary but the carrier and warranty terms remain the same.

Questions about this item
How do I install the 2.5" SAS drive into a hot-plug server bay, and what step is often missed?
Slide the 652611-B21 into the carrier until the SAS connector seats firmly, then lock the carrier latch; the step often missed is fully engaging the latch so the drive registers as hot-pluggable.
What maintenance or replacement will the 300GB 15000 RPM drive need later?
The sealed 15.6 mm mechanism has no user-serviceable parts; plan to replace the entire drive after its rated service life or if SMART attributes report reallocated sectors.
What limit appears first on the 6Gb/s SAS link during sustained writes?
The 6Gb/s SAS interface caps sustained throughput, so long sequential writes will hit the bus ceiling before the 15000 RPM platters become the bottleneck.
