3 TB 7200 RPM SATA desktop drive

The DELL 55H49 is a 3 TB 3.5-inch desktop internal hard drive spinning at 7200 RPM with a SATA III interface. It is built for users who need high-capacity magnetic storage in a standard desktop bay. The drive arrives new and uses the familiar SATA connector for broad motherboard compatibility.

Suits bulk storage not high-speed tasks

This drive suits builders adding large-volume storage for media libraries backups or archival workloads where sequential throughput matters more than random access speed. It is not for systems that require solid-state speeds or low-latency random access. It is also not for compact chassis limited to 2.5-inch bays or for servers that demand a true SAS interface.

SATA III interface decides fit

The single specification that decides fit is the SATA III interface. Any desktop board with a free SATA port and a 3.5-inch mount can accept the drive without adapters or protocol conversion. If the host only offers SAS ports or M.2 slots this drive will not connect.

Highlights

  • 3 TB capacity stores large data sets
  • 7200 RPM rotation speed delivers responsive performance
  • SATA III interface connects to standard controllers
  • 5 inch form factor fits desktop drive bays

Questions about this item

What type of SATA host controller or backplane do I need to run this 3.5" 7200RPM SAS drive?

The drive connects through a standard SATA III interface, so any motherboard or RAID card with a free 6 Gb/s SATA port will recognise the 3 TB ST3000NM0023.

Can I mix this 3 TB 7.2K SAS unit with older 3 Gb/s SATA drives on the same controller?

Yes — the SATA III link negotiates down to 3 Gb/s automatically, letting the 55H49 share a port multiplier or backplane with legacy drives.

How do I confirm the 3 TB capacity and 7200 RPM speed are detected correctly after installation?

Check BIOS or your OS disk utility; it should show model ST3000NM0023, 3000 GB capacity and 7200 RPM rotational speed.
