900GB 15K SAS Enterprise Drive
This Seagate ST900MP0146 is a 900GB 3.5-inch internal hard drive built for enterprise storage workloads. It spins at 15000 RPM and connects through a SAS 12Gb/s interface with a 256MB cache. The drive is supplied as a bare unit in new condition. It targets servers and arrays that need sustained high-throughput performance.
Suits high-transaction servers.
The 15000 RPM spindle and SAS 12Gb/s link suit database clusters, virtualization hosts and other I/O-bound applications where low latency matters more than raw capacity. Buyers who need larger single-drive capacities or lower power draw should look at alternative form factors or speeds. This drive is not designed for desktop PCs or consumer NAS boxes that lack SAS controllers.
SAS 12Gb/s interface decides controller fit
The single specification that determines compatibility is the SAS 12Gb/s interface. Your backplane, HBA or RAID controller must support this exact protocol and speed for the drive to function. No other interface or speed is supported by this model.

Questions about this item
What throughput does the SAS 12Gb/s interface actually deliver?
The SAS 12Gb/s interface provides up to 12 Gbit/s bandwidth, though real-world sustained transfer depends on the 15000 RPM platters and 256MB cache.
What physical space and mounting does the 3.5-inch form factor require?
This drive fits a standard 3.5-inch internal bay and uses the industry-standard SAS connector for power and data.
How is the drive installed, and what step is often missed?
Mount the bare drive in a 3.5-inch bay, attach the SAS data and power cables, then ensure the controller firmware recognises the 4Kn/512e sector format before partitioning.
