IBM 00FN457-RFB is a hot-plug hard drive for server and data-storage systems. Its 146 GB capacity provides drive space for supported storage configurations, while the 2.5-inch form factor suits systems designed for this drive size.
The drive uses a 6 Gb/s SAS interface and spins at 15,000 RPM. Hot-plug support is intended to make drive replacement possible without shutting down the system, where the server or storage array supports that function.
