Capacity and interface

This is a 3.5 inch internal hard drive with a 3 TB capacity and a 7.2 K RPM spindle speed. It connects through a SAS interface and is supplied in new condition. The part carries the Dell 55H49 designation and is packaged for retail or OEM channels.

Suitable workloads and limits

The drive suits nearline storage arrays, backup targets and bulk data repositories that value capacity over low latency. It is not intended for high-transaction databases, boot volumes demanding fast random access, or systems that lack a SAS host adapter.

Deciding specification

The SAS interface is the single specification that determines whether this drive can be installed; the host must provide a compatible SAS connector and controller support for 3.5 inch nearline drives.

Questions about this item

What drive bay size does the 3.5-inch form factor require?

The 3.5-inch form factor fits a standard 3.5-inch internal drive bay in a desktop chassis or server enclosure.

How is the SAS drive installed, and what step is often missed?

Mount the drive in the bay, then attach the SAS data and power cables; the step often missed is securing both connectors firmly so they do not loosen under vibration.

What maintenance will the 7.2K RPM nearline drive need later?

No scheduled mechanical maintenance is required; monitor SMART health attributes and replace the drive if reallocated sectors or seek errors increase.
