HNX0W is the Dell part number for a 4TB 3.5 inch SAS hard drive built on the Toshiba MG04SCA40EN. The MG04SCAxxEN series is enterprise capacity storage in the 512 native format, built for mid-line and nearline business-critical workloads, tier 2 servers and capacity-optimized storage systems. The 4TB MG04SCA40EN is the larger of the two capacities in the series; the other is 2TB.
The platters turn at 7,200 rpm and average latency is 4.17 ms. A 128 MiB buffer supports a sustained transfer rate of 195 MiB/s on the dual-port 12.0 Gbit/s SAS-3.0 interface, which also negotiates 6.0, 3.0 and 1.5 Gbit/s. The drive is rated for 550 TB transferred per year, with 24 x 7 operation.
Reading or writing draws up to 11.8 W, and low-power idle is 6.1 W typical. MTTF is 1,400,000 hours with an error rate of 10 errors per 10^16 bits read. The case is the standard 3.5 inch, 26.1 mm high form factor, up to 147 mm long and 720 g, and it operates from 5 to 55 C.
