300 GB 15K SAS drive

This 300 GB 2.5 inch SAS hard drive spins at 15000 RPM and includes a hot-swap tray. It is built for server workloads that demand fast sequential access and high transaction rates. The 6 Gb/s interface fits standard enterprise backplanes.

Thermals and power

At 15000 RPM the drive generates more heat and vibration than slower spindle speeds. Typical server chassis provide directed airflow across the 2.5 inch bays to keep temperatures in check. Power draw rises during heavy random I/O but remains within the limits of a standard SAS backplane supply.

Upgrade path

The drive replaces lower-capacity or lower-RPM SAS units in hot-swap arrays. The jump is worth it when response time and sustained throughput are bottlenecks. Buyers who need larger capacity per bay or solid-state latency should evaluate other media.

Questions about this item

How do I install the 81Y3812 drive and its hot-swap tray in a 2.5" SAS bay?

Slide the drive into the supplied tray until the connector seats, then insert the tray into the hot-swap bay until the latch clicks; the SAS interface carries both data and power so no extra cables are required.

What maintenance or replacement will the 15000 RPM SAS drive need later?

Mechanical wear on the spindle and actuator is the primary aging factor; plan to replace the drive when SMART reallocated-sector counts rise or after the vendor-rated service life is reached.

Which limit appears first during sustained writes on the 300GB 6Gb/s SAS drive?

The 6Gb/s SAS interface caps sustained throughput, so the bottleneck is the link speed rather than the 15000 RPM media transfer rate.
