120 GB SATA desktop drive
This 3.5 inch internal hard drive offers 120 GB of storage on a SATA interface. It spins at 7200 RPM and includes a 2 MB cache buffer. The drive is supplied new and suits desktop PCs requiring basic magnetic storage.
SATA interface and capacity limits
The SATA connection caps transfer speed at the bus maximum, which is lower than modern PCIe alternatives. Mechanical latency and the 120 GB capacity restrict use to light workloads or secondary storage. Buyers needing larger volumes or faster access should consider higher-capacity or solid-state options.
