Who this suits

Questions about this item

What 3.5" SAS drive bay and backplane does the ST1000NM0001 Constellation need?

It fits a standard 3.5 inch SAS drive bay and connects to a 6 Gbps SAS backplane with the integrated connector.

How is the 1TB 7200RPM SAS drive installed, and what step is often missed?

Slide it into the hot-swap tray, lock the lever, and ensure the SAS cable clicks fully into the backplane port.

When will the 64MB cache Constellation drive need replacement in a RAID array?

Replace it when SMART reports reallocated sectors or the RAID controller flags a predictive failure.
