R87FK is the Dell part number for a 1.92TB 12Gb/s SAS solid state drive that uses the Toshiba PX04SRB192. The PX04SR family comes in 3,840, 1,920, 960 and 480 GB capacities, and the 1,920 GB point is the one this part number carries.
The PX04SRB192 stores data on MLC flash behind a SAS-3.0 interface that negotiates 12.0, 6.0, 3.0 or 1.5 Gbit/s. In dual port mode at 12.0 Gbit/s the sustained 64KiB sequential read speed is 1,900 MiB/s and the sustained 64KiB sequential write speed is 850 MiB/s. Sustained 4KiB random read is 270,000 IOPS and random write is 22,000 IOPS.
Endurance is rated at 1 drive write per day, and mean time to failure is 2,000,000 hours. The supply is 5 V and 12 V with a 7 percent tolerance, and ready power is 3.2 W typical.
The case is 2.5 inch with a 15.0 mm height, 69.85 mm width and a length of up to 100.45 mm, and it weighs at most 150 g. Operating temperature runs from 0 to 55 C at 5 to 95 percent humidity, with 1,000 G operating shock for 0.5 ms. A smaller Dell drive from the same Toshiba series is the 06VJ7, and the 2H9WV uses the Toshiba PX02SSF040.
