We track 27 active MDD products, 16 of which have a buyable offer right now, all of them hard drives. Capacities run from 2TB to 22TB, which is the practical range to plan around rather than whatever the manufacturer's full line-up contains - a capacity nobody stocks is not a capacity you can buy.
On interface, the catalogue is SATA-6G (16), SAS-12G (10) and SAS-6G (1). That matters more than it sounds: a SAS drive needs a host bus adapter, a U.2 drive needs a backplane or an adapter, and neither will work in a machine expecting the other. Check the interface column on every row before you buy on price alone.
The cheapest MDD listing we can currently price works out at $20.00 per terabyte, which is well below the $41.67 median across every hard drives brand we track. That comparison is the useful one. A headline price tells you what a drive costs; the rate per terabyte against the category median tells you whether this manufacturer is where your money goes furthest today.
Concretely, that entry point is the 3TB SAS 6G 7200RPM at $59.99, while the largest thing they have in stock is the 20TB SATA 7200RPM NAS at 20TB for $509.99. Those two rows bracket the range: one is the cheapest way in, the other is the most capacity on a single unit, and the right answer is usually neither extreme.
MDD appears here in both conditions - 3 new listings and 13 recertified or used - and they are genuinely different purchases rather than the same product at two prices. New carries the manufacturer's own warranty term. Recertified carries a reseller's, which is a different promise from a different company, and the discount is the compensation for that. Our recertified guidance covers what to check on arrival.
The seller matters as much as the condition, and the two are shown separately for a reason. A listing fulfilled by Amazon can still be sold by a third party, and in a market where prices have risen sharply that distinction is worth the thirty seconds it takes to read. Our channel and counterfeit guidance covers what to look for at the point of purchase.
If you have settled on MDD, the table above is the whole picture and the cost-per-terabyte column is the ranking that matters. If you have not, the category pages are the better starting point, because they put this brand beside every other one we track at the same capacity rather than in isolation.
On price, their cheapest current listing works out at $20.00 per terabyte against a $41.67 median across every brand we track in the same category. That is the comparison we can make from live data. Whether a specific drive suits your workload is a separate question the table above cannot answer for you.
27 hard drives. That is what has listings we can verify and price, rather than everything the manufacturer produces.
Both — 3 new and 13 recertified or used in stock right now, labelled per row. They are different purchases: new carries the manufacturer's warranty, recertified carries a reseller's, and the price gap is the compensation for that difference.
From 2TB to 22TB across what we currently track. Availability at any single size moves week to week, so the table above is the authority rather than the range.
Every few hours, from the live listings themselves. Cost per terabyte is computed from that price and the product's real capacity, so a listing that changes price changes its ranking on this page without anyone editing anything.
