Questions about this item

Does the ST32000NT000 ship with cables or mounting brackets, or must I buy them separately?

The drive is supplied as a bare 3.5" unit; SATA data and power cables plus any mounting screws or trays are not included and must be sourced separately.

This model is listed as 32TB CMR — are there smaller IronWolf Pro capacities that use the same 7200 RPM and 512MB cache?

Yes, the IronWolf Pro line spans multiple capacities up to 32TB, all sharing the 7200 RPM spindle speed and 512MB cache while using CMR recording technology.

What does the 32TB rating mean once the drive is formatted and running in a NAS array?

After formatting, the usable space is slightly below 32TB; the CMR design and 7200 RPM speed deliver consistent 24x7 throughput for multi-bay RAID workloads.
