HGST (Hitachi Global Storage Technologies) was acquired by WD in 2012 and its enterprise lines merged into the Ultrastar brand. HGST drives still appear on the market as refurbished datacenter pulls. The Ultrastar He series pioneered helium-sealed technology. HGST drives are known for above-average reliability in Backblaze's public drive failure statistics.

For the enterprise line in depth, WD Ultrastar prices carries the part-number decoder and live new-versus-refurbished pricing on both tracks. The retail/channel enterprise SATA line is covered on the WD Gold hub, with WD Gold 26TB, WD261KRYZ, Gold versus HC590 and Gold versus Red Pro pages for the 26TB decisions. The surveillance line, WD Purple and Purple Pro, is priced alongside its Seagate counterpart on the SkyHawk page, where the workload rating and recording technology are recorded per part number. For the high-capacity Purple Pro decision, start with WD Purple Pro 26TB, Purple Pro versus Red Pro and Purple Pro 26TB versus 24TB. The NAS line is on the WD Red page, which decodes Red, Red Plus and Red Pro by model-number suffix and answers the CMR-or-SMR question from WD's own documents rather than from the name on the listing.

What HGST covers here

We track 23 active HGST products, 21 of which have a buyable offer right now, all of them hard drives - the HUS724030ALS640 3TB SAS 6G and the 12TB SAS 12G 7.2K among them. Capacities run from 1.2TB to 12TB, 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 SAS-12G (9), SAS-6G (3) and SATA-6G (2). 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.

Where HGST sits on price

The cheapest HGST listing we can currently price works out at $15.13 per terabyte, which is well below the $43.75 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 HUS724030ALS640 3TB SAS 6G at $45.39, while the largest thing they have in stock is the 12TB SAS 12G 7.2K at 12TB for $595.00. 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.

New, recertified, or both

HGST appears here in both conditions - 11 new listings and 10 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.

Where to go from here

If you have settled on HGST, 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.

Frequently Asked Questions

On price, the cheapest current listing (HUS724030ALS640 3TB SAS 6G) works out at $15.13 per terabyte against a $43.75 median across every brand we track in the same category. That is the comparison we can make from live data. Whether it suits your workload is a question the table cannot answer for you.

14 hard drives. That is what has listings we can verify and price, rather than everything the manufacturer produces.

Both - 11 new and 10 recertified or used in stock right now, labelled per row (the cheapest overall is the HUS724030ALS640 3TB SAS 6G). They are different purchases: new carries the manufacturer's warranty, recertified a reseller's, and the price gap is the compensation.

From 1.2TB to 12TB across what we currently track; the largest in stock is the 12TB SAS 12G 7.2K. Availability at any single size moves week to week, so the table above is the authority rather than the range.
