Server-grade SAS storage

The Toshiba HDD3A02 is a 3.5-inch internal hard drive built around a Serial Attached SCSI interface for enterprise environments. It delivers 1TB of capacity at 7200 RPM with a 16MB cache, targeting administrators who need reliable nearline storage in compatible servers or external arrays.

Capacity and headroom

One terabyte provides ample room for operating-system images, application binaries and moderate database workloads on a single spindle. The 7200 RPM spindle and 16MB buffer sustain steady sequential throughput, but random I/O-heavy tasks such as heavy virtualisation or transactional databases will exhaust IOPS headroom before the space fills.

Bare-drive delivery

The unit ships as a bare drive without cables, brackets, mounting screws or management software. Integration therefore requires a backplane or controller that supplies SAS power and data connectors plus any mechanical hardware the chassis demands.

Questions about this item

Will the 3.5" SAS drive fit the same drive bay as the 3.5" SCSI drives I am replacing?

Yes, the 3.5 inch form factor matches standard 3.5 inch bays, so it will mount in the same slots as your existing 3.5 inch drives.

How can I confirm the drive is running at its rated 7200 RPM after installation?

Use the server RAID controller BIOS or a SMART monitoring tool to verify the rotational speed reports 7200 RPM and that the SAS link negotiates at 6 Gb/s.

The listing says Bare Drive — does that mean I only receive the drive without cables, brackets or screws?

Correct, Bare Drive means the 1 TB unit ships alone; you must supply your own SAS data cable, power cable and any mounting screws or trays your chassis requires.
