Google shopping shows me a 4TB WD Red at $110. A two-drive esata bay is under $100. Btw, for anything like this, DO NOT BUY consumer grade drives. Make *sure* they're NAS-rated, like WD Red or Seagate Ironwolf. mark

Google shopping shows me a 4TB WD Red at $110.5400 RPM. Red Pros are $170 at NewEgg, and we?re using WD Golds at $199. That?s $50/TB, but the $37/TB mark is for higher capacity drives. Even if we take your numbers and halve them again to get miracle high-quantity pricing, the payoff time at the OP?s wished-for $1/TB/year is about 14 years, and we haven?t even added in ancillary costs like the enclosure, redundancy, power, cooling, networking, staff, drive replacement?> A two-drive esata bay is under $100.?which won?t hold 50 TB of data. Even a 4-drive enclosure isn?t enough, since even with single redundancy, the largest drives are 15/16 TB, depending on the technology, so that only gets you 45 or 48 TB. And then you?ve got to work out how to use those SMR or MAMR drives efficiently. Stepping back to standard technology 10 TB drives requires 7 of them to get 50 TB with dual redundancy, so even with miracle pricing, you?re probably talking about something like $750 for the raw hardware, which gets paid back in ~15 years on the OP?s schedule, and then only if all 7 drives last 15 years! Tell ?im ?e?s *dreamin?!*.
