This 300GB LFF-form-factor drive from the HPE Server HDD range spins at 15,000 rpm and connects over SAS at up to 12Gb/sec synchronous transfer. Its formatted size is 300,000 MB, which equals 585,937,500 logical blocks, and it is built with digitally signed firmware.
Seek performance is rated at 0.22 ms single track, 2.72 ms average and 5.36 ms full stroke. The 300GB drive sits in a Low Profile Converter (LPC) carrier, which measures 1.028 in (26.1 mm) high, 4.15 in (105.5 mm) wide and 6.16 in (156.58 mm) deep.
It is the 300GB model in the 15K rpm Enterprise class and the data format is 512 bytes per sector. Operating temperature runs from 50 to 95 degrees F (10 to 35 degrees C).
In the same LPC carrier, the 600GB 15K drive is 797283-B21 and the 900GB signed-firmware model is 870761-B21, while the 300GB capacity in an SFF Smart Carrier with signed firmware is 870753-B21. The 300GB unit raises Pre-Failure Alert warnings when it is paired with a Smart Array controller and Systems Insight Manager.
