Compare a Pro model
Consider the Pro model when its published workload and warranty terms fit your requirements.
Tradeoff: The Pro name does not by itself make a light home workload faster. Check whether the premium buys something you need.

*Illustrations for equal-capacity drives: RAID 1 mirrors two drives; four-drive RAID 5 reserves one drive’s equivalent capacity for parity. Figures are decimal TB before filesystem and system overhead. Costs are the displayed unit price × quantity, excluding tax, shipping and enclosure; seller quantity limits and prices may vary. RAID does not replace a backup. Understand RAID tradeoffs · RAID capacity reference.

Specifications: linked manufacturer model pages. Selection covers different capacities and families; it is not a reliability ranking. Prices are per listed drive; Amazon’s price and availability at purchase apply.
Compatibility first
Check the exact model, interface, supported drive bays and sector format against your enclosure. Do not substitute a SAS variant for a SATA model.
Choose capacity for the array
Work out usable space after redundancy, then compare the total cost of all drives. Keep backup storage separate from the array.
Compare the offer after the model
Manufacturer specifications do not establish seller warranty, renewed condition or availability. Each model page links directly to verified Amazon ASINs where an exact listing has been matched.
