4TB SATA 6Gb/s 3.5-inch hard

Lenovo ST4000NM002A-RFB is a refurbished hard disk drive for expanding computer or server storage. Its 4TB capacity provides space for large collections of files and business data, while the 3.5-inch form factor suits systems built for this drive size.

The drive uses a SATA interface and spins at 7200 RPM. The listing specifies 512e sectors and 128MB of cache, and describes it as designed for enterprise applications. These details make it suited to adding storage in a compatible system where a 3.5-inch SATA hard drive is supported.
