17 in-stock listings out of 24 tracked; the cheapest is the WD WD Purple 4TB WD40PURX at $117.37 ($29.34/TB). The table on this page is the live ranking.
Both are in stock: 8 new and 9 recertified or used. The cheapest new is the WD Ultrastar 7K4000 4TB SATA NAS at $199.91, the cheapest recertified or used the WD WD Purple 4TB WD40PURX at $117.37 - a 41% shelf gap between two different models, not a like-for-like discount. New carries the manufacturer's warranty; recertified a reseller's.
8 of the 24 tracked listings carry a manufacturer-sourced conventional (CMR/ePMR) recording value, including the WD WD Red Pro 4TB WD4003FFBX and the WD WD Red Plus 4TB WD40EFZZ. 16 are not sourced either way - an unsourced drive is never assumed CMR here.
