Dell 4TB SATA internal drive

This Dell 9ZM170-136 hard drive provides 4TB of storage in a 3.5 inch form factor. It spins at 7200RPM and connects through a SATA 6Gb/s interface. The unit includes a 128MB buffer and is shipped new from the manufacturer.

Verify 3.5 inch bay and SATA cabling

Check that your chassis has an available 3.5 inch drive bay before ordering. Confirm the motherboard or controller offers a free SATA 6Gb/s port and that a matching data cable is present. Ensure the power supply includes a spare SATA power connector for the drive.

Sustained throughput at 7200RPM

The 7200RPM spindle speed maintains consistent transfer rates during long write sessions. The 128MB cache absorbs burst traffic to keep the platter streaming steadily. Mechanical latency remains stable because the rotational speed does not throttle under continuous load.

Questions about this item

Does the 9ZM170-136 ship with mounting hardware or cables, or do I need to buy them separately?

The drive is supplied as a bare 3.5" SATA unit; rails, screws and data cables are not included and must be sourced separately

There are two model numbers listed — ST4000NM0033 and 9ZM170-136 — which one should I order for a Dell R730?

Both numbers refer to the same 4TB 7200RPM drive; 9ZM170-136 is the Dell part number validated for the R730 and other Gen13 servers listed

What does the 7.2K RPM rating mean for everyday use in a Dell T430?

It delivers 7200RPM spindle speed with a 128MB cache on a 6Gb/s SATA link, giving consistent throughput for bulk storage and nearline workloads
