Questions about this item

Does the drive ship with any cables, brackets or mounting screws, or do I need to supply them?

The drive is supplied as a bare 3.5 inch unit; SATA data and power cables plus any mounting hardware must be provided separately.

The WD Gold line lists capacities up to 26TB, so why choose the 24TB model instead of the maximum?

The 24TB version keeps the same 7200 RPM speed and 512MB cache while costing less per drive, which suits arrays that need many spindles rather than maximum single-volume capacity.

What does the 2.5M hour MTBF figure mean for a drive running 24/7 in a RAID array?

It is a population reliability metric indicating the drive family is designed for continuous enterprise workloads, not a guarantee for any single unit.
