Capacity and pricing note: Use the controls above to estimate equal-size array drives. Essential uses single parity; Business and Advanced use dual parity. SSD cache is separate. Estimates use current conservative drive costs, the required 30% markup, and the fixed $300 build fee. Actual formatted capacity is lower, and final pricing is confirmed against live inventory before ordering.

Pricing basis

Current estimates use stable refurbished-server vendors for the chassis and warranty baseline, enterprise-drive specialists for storage, Amazon for broadly available SSD comparisons, and eBay Buy It Now listings only to check the wider used-market range.
