Seagate ST4000NM0023 4TB 7200RPM SAS 128MB 3.5" internal hard drive

Enterprise SAS Drive

The Seagate Constellation ES.3 ST4000NM0023 is a new 4000GB internal hard drive built for server environments. It spins at 7200RPM and connects through a 3.5-inch SAS interface operating at 6Gb/s. A 128MB buffer helps sustain throughput during heavy workloads. The unit weighs 2.0 pound.

Server Deployments Only

This drive suits administrators expanding storage arrays or replacing failed disks in compatible SAS backplanes. Buyers needing a drive for a desktop PC or laptop cannot use this product because the interface requires a SAS controller. Shoppers who want a consumer-formatted drive should look elsewhere. The 90-day warranty covers initial deployment.

6Gb/s SAS Interface

The single specification that decides fitment is the 3.5-inch SAS connection running at 6Gb/s. Your host bus adapter or backplane must support this exact interface and signalling standard. Without a compatible SAS controller the drive will not function. Verify the controller specification before purchase.
