Dell 55H49 3 TB SAS drive

The Dell 55H49 is a 3.5 inch internal hard drive with a 3 TB capacity and a 7200 rpm spindle speed. It uses a 6Gb/s SAS interface and ships in a hot-swap tray for large form factor bays. The drive is supplied new and ready for installation in compatible servers or storage arrays.

Who this suits and who it does not

This drive suits administrators who need a 3 TB SAS drive with a 6Gb/s interface and a hot-swap tray for a supported Dell chassis. It is not for systems that require a different interface or that cannot accept a 3.5 inch LFF hot-swap tray.

Deciding specification

The 6Gb/s SAS interface is the single specification that determines whether this drive will work in your system. Your backplane and controller must support SAS at 6Gb/s and accept a 3.5 inch LFF hot-swap tray for the drive to function.

Questions about this item

Will the 55H49 3TB drive fit and connect in my existing 3.5" hot-swap bay?

The drive uses a 3.5 inch LFF form factor and a 6Gb/s SAS interface, matching standard 3.5" hot-swap bays built for SAS drives.

Can I run this 7200 rpm SAS drive on the same backplane as my older 7.2k RPM SAS drives?

Yes, the 6Gb/s SAS link negotiates speed automatically, so the 55H49 will operate alongside existing SAS drives on the same backplane.

How do I verify the 3TB capacity and 6Gb/s link are active after installation?

Check the RAID or HBA BIOS during boot; it should list the 55H49 at 3 TB capacity and show a negotiated 6Gb/s SAS link speed.
