Best Hard Drive Deals in May 2026: What's Actually Worth Buying
Read this first, updated 6 August 2026. This is a May 2026 snapshot and prices have moved a long way since. The figures below are what things cost in May. They are not what you will pay today.
What changed: enterprise 16 TB was around $12 to $13/TB in May. As of 6 August 2026 the cheapest 16 TB on Amazon.com is $29.00/TB new and $24.94/TB used, against a new-drive median of $55.40/TB.

May is looking interesting for storage buyers. After a pretty rough Q1 where prices climbed steadily (I wrote about why HDD prices are rising if you missed it), we’re finally seeing some stabilization in the 14-18TB range. Not a crash, but the bleeding has stopped, and a few models are genuinely well-priced right now.
Here’s my breakdown for May 2026. As always, you can check the live deals page for current pricing. I update it daily.
The Short Version
Best value this month: 16TB enterprise drives. The Exos X16 and Ultrastar HC550 in 16TB are sitting at some of the best per-TB pricing we’ve seen in months. If you need capacity for a NAS or server build, this is the range to buy.
Avoid: anything under 8TB unless you have a specific reason. The per-TB math just doesn’t work at smaller capacities anymore.
Top Picks for May
Best Overall: 16TB Enterprise CMR Drives
The 16TB sweet spot from April continues into May, and pricing has actually improved slightly. Seagate Exos X16 and WD Ultrastar DC HC550 are both enterprise-grade CMR drives with 5-year warranties and workload ratings that dwarf consumer models.
Why these are my pick:
- CMR recording, no RAID rebuild anxiety. (CMR vs SMR explained)
- 550TB/year workload rating
- Built for 24/7 operation
- Price per TB is competitive with consumer drives
The 16TB Exos is the default pick at this capacity for a reason: it is usually the cheapest per terabyte of any CMR drive you can put in an array.
Best for NAS Builders: 12-14TB Range
If 16TB is more than you need, the 12-14TB range is where NAS-optimized drives like the Seagate IronWolf and WD Red Plus live. They’re designed for multi-bay enclosures with vibration sensors and optimized firmware for RAID.
Not sure which NAS drive to pick? I compared the two most popular options: IronWolf vs IronWolf Pro and WD Red vs Seagate IronWolf.

Best Budget: Refurbished Enterprise Pulls
If you’re building a Plex server or cold storage array and don’t need a manufacturer warranty, recertified enterprise drives are still the best bang for your buck. Datacenter pulls (drives that ran in a server farm for 2-3 years and got replaced during a refresh cycle), regularly come in at 40-60% below new pricing.
The key is buying from reputable sellers with decent return policies. I track refurbished pricing separately: Best Refurbished HDD Deals
Fair warning: these come with shorter seller warranties (typically 1-2 years vs 5 years for new enterprise drives). But at half the price, many of us consider that a good trade.
Best for Plex & Media: 18-20TB If You Can Swing It
Running a Plex server? Bigger drives mean fewer bays needed, less power draw, and more room to grow. The 18TB and 20TB enterprise drives aren’t cheap in absolute terms, but they deliver solid per-TB value when they’re in stock.

What to Avoid in May
Small Drives at “Sale” Prices
I see this every month: 4TB drives listed at $70-80 with a “sale” badge. That’s $17-20/TB. In May, 16TB enterprise drives were running at $12-13/TB, so a 4 TB at that price was poor value.
That comparison has since inverted. As of 6 August 2026 the cheapest new 4 TB is $23.80/TB and the cheapest new 16 TB is $29.00/TB. A 4 TB at $17.50/TB would now be one of the better prices on the site. Do not act on a price in a dated article, this one included.
Overpriced Refurbs
Some sellers are getting greedy with refurbished pricing. I’m seeing recertified drives at only 15% below new prices. That’s not enough of a discount to justify losing the manufacturer warranty. Wait for the 40%+ discounts or just buy new.
SMR Drives for NAS Use
If you’re running any kind of RAID or ZFS array, avoid SMR drives. They’ll work fine for a while, then tank during a rebuild when you can least afford it. CMR only for multi-drive arrays. I wrote a whole thing on this: CMR vs SMR guide.
What I’m Watching in June
- Prime Day 2026: Amazon hasn’t announced dates yet, but summer Prime Day events have historically been great for storage deals. I’ll be tracking every price drop closely when it happens.
- NAND flash pricing: SSD prices keep falling, and at some point they’ll start seriously competing with HDDs for bulk storage. I track the crossover point: SSD vs HDD Price Comparison
- 24TB drives: A few 24TB models are starting to appear. Once pricing normalizes, these could reset the per-TB math entirely.
