Toshiba MK1401GRRB 147GB (2013)

The MK1401GRRB is a “high-performance” 2.5″ SAS model, continuing Toshiba’s presence in the enterprise drive segment. In the modern day, SAS drives of this nature are increasingly less common, yet this example from 2013 fortunately another good drive to look at in good health.

Toshiba tout these as their first drive to feature a dual-stage head positioning actuator.

A decade old.

The label.

As with any Toshiba drive produced under their TDSC branch, this unit was produced in the Philippines. The label is as nifty as ever, with relatively few points of useful information.

The rear.

A blue PCB on the rear is all that’s special, logic faces inwards unlike with earlier Fujitsu SAS 2.5″ models.

The base.

Removing the PCB, the base of the drive bears nothing as expected. The spindle motor has no clear branding! Boo.

The PCB.

The heart of this drive logically is the Marvell 88i9131-BKY2. Winbond supply the 32MB of cache available on this model.

The MK1401GRRB is a fun little 2.5″ drive from the early 2010’s, with this example having had quit the staggering life. Nonetheless, it still functions fine. While the performance isn’t bad as expected, there’s little reason to use this small thing in service. Well, a high-RPM SAS drive is often somewhat entertaining, even if their service may have reached an end.
