8 TB SAS drive for nearline arrays

Replaces smaller 3.5 inch SAS drives

The capacity jump is worthwhile when existing bays hit their limit and the workload still fits a 7.2K spindle. Buyers who need faster random access or a different interface should look elsewhere.

Questions about this item

What 3.5" drive bay spacing and SAS backplane connector does the M40TH need?

The drive fits a standard 3.5" bay and connects to a 12 Gb/s SAS backplane using the native SAS interface.

How is the M40TH installed in a server chassis, and what step is often missed?

Slide the drive into the hot-swap tray until the SAS connector seats firmly, then lock the tray handle; the step often missed is fully engaging the handle latch so the 12 Gb/s link initialises at 7.2K RPM.
