Seagate Constellation ES 500GB SAS 6Gb/s drive

The Seagate Constellation ES ST3500414SS is a 3.5-inch enterprise hard drive built for continuous operation in multi-drive arrays. It delivers 500GB capacity at 7200 RPM with a 16MB cache and a SAS 6Gb/s interface for high-throughput business workloads.

Suited for 24x7 nearline storage.

This drive targets servers and storage enclosures that demand enterprise-class reliability and sustained data rates around the clock. It is not designed for mobile devices, external enclosures without a SAS backplane, or systems that lack a compatible SAS controller.

The SAS 6Gb/s interface dictates host compatibility

A SAS host bus adapter or RAID controller with 6Gb/s ports is required to operate this drive. Without that specific interface the drive cannot communicate with the system, making the SAS connection the single specification that determines fit.

Questions about this item

Should I pick the 500GB SAS model or a different capacity?

This listing is for the 500GB ST3500414SS with a 7200 RPM spindle and 16MB cache. Other capacities exist in the Constellation ES range but are separate part numbers.

What does the 7200 RPM speed deliver in a live server?

The 7200 RPM rotation keeps average latency low for random read and write workloads typical of 24 x 7 business-critical applications.

What does the SAS 6Gb/s interface cap in practice?

The SAS 6Gb/s port limits the maximum bus transfer rate to 6Gb/s; actual throughput depends on the controller and workload.
