Dell 91k8t 3TB SAS drive

The Dell 91k8t is a 3.5 inch internal hard drive with a 3TB capacity and a 7200 RPM spindle speed. It uses a Serial Attached SCSI interface rated at 6 Gbps and includes a 64 MB buffer. The drive is supplied new with a tray for installation in compatible Dell PowerVault servers.

Suited for high-capacity server storage

This drive suits administrators expanding storage arrays in Dell PowerVault systems that accept 3.5 inch SAS drives. The 7200 RPM speed and 3TB capacity support nearline workloads requiring large volumes. Buyers needing a 2.5 inch form factor or a different interface protocol should look at other parts.

SAS 6 Gbps interface determines compatibility

The single specification that decides fit is the Serial Attached SCSI 6 Gbps interface combined with the 3.5 inch form factor. The server backplane and controller must support this exact interface and physical size for the drive to function. Verify the system documentation matches these parameters before purchase.

Questions about this item

Will the 91k8t 3.5" SAS drive install in my existing 6 Gbps SAS backplane?

The 91k8t uses a Serial Attached SCSI interface rated at 6 Gbps, so it connects directly to any standard 6 Gbps SAS backplane without adapters.

How can I verify the 7200 RPM drive is healthy after installation?

Check SMART attributes for reallocated sectors and run a full surface scan; the drive should report zero reallocated sectors and complete the scan without errors.

Does the 91k8t ship with a mounting tray or only the bare drive?

The supplier description confirms the drive includes a tray for PowerVault servers; no separate tray or caddy is required for those chassis.
