Seagate ES 500GB SAS drive

The Seagate ES ST3500415SS is a new 3.5 inch internal hard drive with a 500GB capacity. It spins at 7200 RPM and provides a 16MB cache over a SAS 6Gb/s interface. The bare drive includes secure encryption features.

Suited for SAS storage arrays

This drive fits servers and storage enclosures that accept 3.5 inch SAS drives with hot-swap trays. It operates between 5°C and 60°C and draws 10.4W average operating power. Buyers needing a different capacity or a non-SAS interface should look elsewhere.

SAS 6Gb/s interface decides fit

The drive requires a backplane or controller supporting the SAS 6Gb/s standard. Average seek time is under 8.5ms with 4.16ms average latency. Maximum start current is 1.89 on the DC supply.
