Toshiba 1 TB SAS enterprise drive

This 3.5-inch nearline hard drive delivers 1 TB of storage on a 6 Gb/s SAS interface, spinning at 7200 RPM with 64 MB cache. It is built for continuous 24 x 7 operation in server and storage-array environments.

Suits always-on server arrays.

The drive targets servers and storage arrays that run continuously and benefit from rotational-vibration safeguards and enhanced power-condition states. Systems requiring a different physical interface or a smaller form factor cannot use this unit.

6 Gb/s SAS interface decides compatibility

A SAS host bus adapter or controller with 6 Gb/s support is mandatory; the drive will not function on ports that only provide other signalling types. The 26.1 mm height fits standard 3.5-inch drive bays in rack and tower chassis.

Questions about this item

How does the 7200 RPM speed affect performance in a server?

The 7200 RPM spindle delivers consistent throughput for mixed read and write workloads typical of 24x7 nearline storage.

What does the SAS 6Gb/s interface limit in practice?

The SAS 6Gb/s link caps the maximum burst transfer rate at 6Gb/s, while sustained rates depend on the 64MB cache and platter density.

Will the 26.1 mm height fit a standard 3.5-inch drive bay?

Yes, the 26.1 mm height matches the standard 3.5-inch form factor used in most server and workstation bays.
