861681-B21 is the HPE 2TB SATA 6G Business Critical 7.2K LFF low-profile (LP) hard drive, supplied as a Multi Vendor HDD. It is a 512n-format drive. It is a 3.5-inch large form factor drive that spins at 7,200 rpm and links at up to 6 Gb/s over SATA.
HPE rates the drive at 185 MiB/s maximum sequential throughput from the outer-diameter media. With 128 KiB random access it is rated at 90 IOPs for reads, 90 IOPs at a 70% read
30% write mix and 90 IOPs at a 50/50 mix. Power draw is 8.8 W idle, 12.2 W under random read/write, 10.8 W for sequential reads and 10.5 W for sequential writes.
The low-profile carrier measures 1.028 in (26.1 mm) high, 4.15 in (105.5 mm) wide and 6.16 in (156.58 mm) deep, and HPE gives the operating range as 10 to 35 C (50 to 95 F). The spare drive for this option is 862132-001, a 2TB SATA 6 Gb/s, 7,200 rpm, 3.5-inch LFF low-profile unit. HPE sorts Business Critical drives as its midline high-capacity class, with backup, archive and reference storage as the stated usage.
The same 2TB capacity is also offered in a Smart Carrier as 872489-B21, which HPE rates at the same 185 MiB/s and 8.8 W idle. More drives are in the HPE HDD category.
