Seagate Cheetah NS 400GB 10000 RPM SAS Drive
This Seagate Cheetah NS ST3400755SS is a 3.5-inch internal hard drive with a 400GB capacity and a 10000 RPM spindle speed. It connects via a SAS 3Gb/s interface and includes a 16MB cache. The drive is supplied as a bare unit and is designated for NAS systems.
Buyers needing SAS 3Gb/s 10K storage
This drive suits NAS deployments and servers that accept a 3.5-inch SAS 3Gb/s device running at 10000 RPM. It is not for systems that lack a SAS backplane or controller. It is also not for users who require a manufacturer warranty, as the product is end-of-sale and covered only by the seller's one-year warranty.
10000 RPM spindle speed decides fit
The 10000 RPM rotation rate determines the drive's average seek time of 3.9ms, average write time of 4.2ms and average latency of 2.98ms. Verify that the target chassis and controller support this speed and the SAS 3Gb/s interface before purchasing.
