P54678-001 is the HPE spare for the P53554-B21 drive, the HPE 20TB SATA 6G Business Critical 7.2K LFF LP helium 512e ISE multi-vendor hard drive. The spare itself is the 20TB 7.2K LFF SATA LP ISE MV drive.
The drive spins at 7,200 rpm and uses a SATA interface with a 6Gb/s maximum synchronous transfer rate. It fits a 3.5-inch large form factor low-profile carrier that is 1.028 in (26.1 mm) high, 4.15 in (105.5 mm) wide and 6.16 in (156.58 mm) deep, with 512-byte sectors and an operating temperature of 50 to 95 degrees F (10 to 35 degrees C).
Sequential throughput at the outer diameter reaches up to 249 MiB/s. Random 128 KiB reads reach 110 IOPS, and mixed random work reaches 118 IOPS at 70 percent read and 30 percent write, or 130 IOPS at 50 percent read and 50 percent write.
Power draw is 5.8 W idle, 9.3 W under random read and write, 8.1 W on sequential reads and 8.6 W on sequential writes. The SAS version of the same 20TB drive is P53553-B21, and further HPE drives are in the HPE hard drive range.
