DELL 55H49 3TB SAS drive

The DELL 55H49 is a 3.5-inch internal hard drive built for desktop systems that accept a SAS connection. It spins at 7200 RPM and provides three terabytes of storage for bulk data workloads. The unit is supplied new and may arrive in retail or OEM packaging. First listed by the manufacturer in 2020, it carries the part identifier 55H49.

Suited for SAS-equipped desktops

This drive fits workstations or servers that have a native SAS backplane or controller and need high-capacity nearline storage. It is not intended for laptops, external enclosures or any platform that lacks a 3.5-inch drive bay and a SAS interface. Buyers who require a different physical format or a different interface should consider other options.

7200 RPM spindle speed

The 7200 RPM rotation rate determines the sustained throughput and access latency you can expect from this nearline SAS drive. It is the primary performance figure that decides whether the device meets the speed requirements of your storage array or backup target. Verify that your system supports this speed class before purchase.

Questions about this item

How do I install the 3.5in SAS drive in a desktop, and what step is often missed?

Mount the drive in a 3.5in bay, connect the SAS data cable to a compatible controller and attach the SAS power connector; the step often missed is confirming the controller supports 6 Gb/s SAS before booting.

What maintenance or replacement will the 7200RPM SAS drive need later?

Plan to replace the mechanical drive after its rated service life; monitor SMART attributes for reallocated sectors and keep firmware current via the controller utility.

What limit appears first during sustained transfers on this 3TB 7200RPM SAS drive?

The 7200 RPM spindle speed caps sustained throughput, so sequential read/write rates plateau well below the 6 Gb/s SAS interface ceiling.
