Black Friday Hard Drive Deals, Judged by Price per TB

A real Black Friday hard drive deal costs less per TB than drives of the same size and condition typically cost today — not just less than a seller's reference price. The list below shows only offers that pass that test, best deal first.

NAS builders, Plex and media-server owners, and anyone stocking backup drives tend to buy several drives at once, and Black Friday is when many of them buy. The list below shows today's Amazon offers on hard drives of 4TB and up that cost less per TB than typical for their capacity and condition — new, renewed, or used — ranked best deal first, refreshed daily, with each price's capture time.

Sale season brings percent-off badges on everything. Those compare a drive with a reference price the seller picked, not with the market. The steadier yardstick is price per TB against what drives of the same size and condition typically cost today. This page runs that math on every offer and lists only the ones that beat typical, so a deal on a small drive can't hide behind a big percentage.

What to look for

Check the recording technology before the badge. SMR drives are cheaper per TB but slow sharply under heavy rewrites; CMR drives handle sustained and random writes predictably, which is what a NAS array or a busy media server needs. A discounted SMR drive is still the wrong drive for that job, whatever the percentage says.

Match the drive class and warranty to the job, not to the discount. Desktop-class drives are rated for about 120 TB of writes a year with 2-year warranties; entry NAS-class for 180 TB and 3 years; pro NAS and enterprise-class for 550 TB and 5 years. A strong price per TB on a desktop drive is not a NAS bargain, so weigh the workload rating and warranty alongside the score.

Buy all the bays at once, and read the fine print on packs and condition. Most RAID setups use every drive at the size of the smallest, so matching capacities matters more than grabbing one bargain — a sale is the practical time to fill an array in a single order. Multi-packs can top a price-per-TB list, and each entry flags them. Renewed drives are scored only against other renewed drives; their warranty comes from the seller, not the maker, and usually runs shorter.

FAQ

When do Black Friday hard drive deals start?

On Amazon, before the day itself. Recent Black Friday events have run about 12 days, starting the week before Thanksgiving and ending on Cyber Monday, with new deals added daily while supplies last. Popular offers can sell out early, so check the list more than once.

Are Black Friday hard drive deals actually good?

Some are, and some only look good. A real deal is priced below today's typical price per TB for its size and condition — the check this page applies to every offer — while a percent-off badge measures only against a reference price the seller chose.

Should I buy NAS drives on Black Friday?

Yes, if you already know the array you want. Filling every bay with the same capacity avoids the wasted space that mixed sizes cause in most RAID setups, and a sale is a natural time to buy several drives at once. Favor CMR recording and a NAS-class or better workload rating over the boldest percentage.

Are renewed hard drives on Black Friday worth it?

They can be, when the price sits below the renewed market. Here a renewed drive is judged only against other renewed drives of the same capacity, so its score reflects today's renewed prices, not new-drive prices. The trade-off is support: the warranty comes from the seller and is usually shorter.
