7FJW4: DELL (ST300MP0005) 300GB 15000 RPM SAS 2.5inch 12Gbs HDD for 13Gen PowerEdge

7FJW4 is the Dell part number for a 300GB 2.5 inch 15K SAS hard drive that carries the Seagate model ST300MP0005, a standard 512 native model of the Seagate Enterprise Performance 15K HDD v5 family. The spindle turns at 15K rpm with 2.0 ms average rotational latency, and a 128MB data buffer sits behind a SAS interface running at 12Gb/s with 1,200 MB/s per port.

The 300GB models use four read/write heads. Sustained transfer rate for 512 native models is 160 to 233 MiB/s, and logical block size defaults to 512 bytes, with 520, 524 and 528 selectable. Mean time between failures is 2,000,000 hours, the annualized failure rate is 0.44 percent, and unrecovered data errors are held to less than one sector in 10^16 bits.

The 300GB model weighs 0.496 lb (0.225 kg) and operates across a 5 to 55 C drive temperature range. In the same 300GB size the family also has ST300MP0015 as the self-encrypting 512 native model, ST300MP0035 as the standard 512 emulation model and ST300MP0065 as the standard 4096 native model, so the model on the label settles which sector format a drive uses.

Other Dell SAS hard drives include the 10K 300GB PGHJG and the 10K 1.2TB T6TWN.
