YKT0W: Dell 900GB 12Gbps SAS 2.5in SFF 15000 RPM (Toshiba AL14SXB90ENY)

AL14SXB90ENY is the Toshiba model number under Dell part number YKT0W. In the AL14SXB series it is the 900GB, 512n (native 512-byte sector) drive with the Sanitize Instant Erase option; the Y suffix marks that option, and the same capacity without it is the AL14SXB90EN. The series also has 512e (EE) and 4Kn (EA) variants.

The platters spin at 15,000 rpm for a 2.0 ms average latency, and the buffer is 128 MiB. The SAS-3.0 interface runs at up to 12.0 Gbit/s and steps down to 6.0, 3.0 or 1.5 Gbit/s. Sustained transfer on 512n models is 259 MiB/s. Persistent Write Cache technology protects cached writes, and logical blocks of 512, 520, 524 or 528 bytes can be set.

Reading or writing draws up to 9.0 W, active idle is 5.6 W typical, and sound power is 33 dB. MTTF is 2,000,000 hours, with 10 errors per 10^17 bits read and 600,000 load and unload cycles, and the drive is rated for 24 hours a day, 7 days a week. The body is 15 mm tall, weighs up to 230 g and operates from 5 to 55 C.

A 15K drive with a lower capacity is the 0RVDT, and Dell hard drives covers more.
