Dell 72Y6W 4TB SAS drive

The Dell 72Y6W is a 4TB 3.5 inch SAS hard drive built for enterprise storage arrays and servers. It delivers 7200 RPM performance over a 6Gb/s interface for nearline workloads.

Bare drive build and SAS connector

Supplied as a bare drive without a tray, it fits standard 3.5 inch bays that accept SAS connectors. The 6Gb/s SAS link provides dual-port redundancy for continuous operation in RAID enclosures.

Verify SAS controller and bay compatibility

Confirm your backplane or HBA supports 6Gb/s SAS and supplies the correct power connector. Ensure the chassis has an open 3.5 inch slot and that your RAID firmware recognises the 72Y6W part number.

Questions about this item

What does the SAS 6Gb/s interface mean for real-world transfer limits on this 4TB drive?

The 6Gb/s SAS link sets the bus ceiling; actual throughput depends on the 7200 RPM platters and workload.

Will the 3.5 inch form factor fit my server tray without an adapter?

The drive is a standard 3.5 inch unit; it mounts directly in any 3.5 inch bay or hot-plug tray that accepts bare drives.

How do I install this Nearline SAS drive in a Dell PowerEdge and what step is often missed?

Slide the bare drive into the carrier, secure the screws, insert the carrier until it clicks, then ensure the RAID controller recognises the new SAS device before initialising.
