Dell 4TB Nearline SAS Drive

The Dell 400-AGCW is a 4TB 3.5" internal hard drive built for nearline storage workloads. It spins at 7200 RPM and connects through a SAS 6Gb/s interface for direct attachment to compatible controllers.

Suits arrays needing high-capacity SAS drives

This drive fits servers and storage enclosures that accept 3.5" SAS devices and require 4TB of capacity at 7.2K speed. Systems without SAS backplanes or controllers cannot use this drive. Buyers needing a different capacity or a 2.5" form factor should look elsewhere.

SAS 6Gb/s interface decides compatibility

The drive communicates over a SAS 6Gb/s link, so the host must provide a SAS port and backplane that support this signalling rate. Without a SAS connection the drive will not function.

Questions about this item

How much power and heat does the 4TB 7200 RPM SAS drive generate during all-day operation?

The 3.5-inch 4TB Nearline SAS drive runs at 7200 RPM with a 6Gb/s interface; power draw and thermal output follow standard enterprise 3.5-inch HDD profiles for this speed and capacity.

What host interface must my system provide for the 400-AGCW to function?

The drive requires a SAS 6Gb/s backplane or controller with a compatible 3.5-inch bay and power connector.

Will the 7.2K 6Gb/s SAS drive work alongside older 3Gb/s SAS drives in the same enclosure?

Yes, the 6Gb/s SAS interface negotiates down to 3Gb/s, so the 4TB drive can share a backplane with slower SAS drives.
