5 Hard Drive Manufacturers You Should Know
Hard Drive Manufacturers and Storage Brands
You Should Know
Your hard drive is where your data actually lives, whether that’s a traditional hard disk drive spinning away inside a desktop or a solid-state drive soldered into a laptop. Capacity, speed, form factor, price: there’s a lot to weigh before you buy. But most people skip the question sitting underneath all of that. Who makes hard drives in the first place?
The answer is shorter than you’d think. As of 2026, only three hard drive manufacturers still build HDDs: Seagate, Toshiba, and Western Digital. That’s it. Several of the biggest names in storage — Samsung, SanDisk, Kingston, Crucial, and HP among them — either left the hard disk drive business years ago or never made hard drives at all. They still belong on this list, though, because they’re where most of today’s flash memory and SSDs come from.
Search for hard drive brands, hard disk brands, or hard disc brands, and you’ll usually get a list that mixes those two groups together. So here’s the hard disk drive company list as it actually stands: what each company makes today, and for the ones that got out, when they got out.
If you landed here because a drive just stopped working, the next section covers how to identify what you have, and what not to do while you work that out.
How to Find Out Who Made Your Hard Drive
On a drive that’s working normally, identifying the manufacturer takes about thirty seconds. The brand printed on the outside often isn’t the company that built the mechanism inside, so the only reliable way to know is to ask your computer.
That model string tells you the manufacturer once you know the prefixes. These cover most of what you’ll run into:
- ST: Seagate
- WDC or WD: Western Digital
- TOSHIBA, MQ, MG, or DT: Toshiba
- HGST, HUH, HUS, or HTS: HGST drives, which Western Digital now owns
- MZ or SAMSUNG: Samsung
- CT: Crucial, manufactured by Micron
It’s also a quick way to catch a surprise. Pull the model string off an external drive, and you’ll frequently find a Seagate, Toshiba, or Western Digital mechanism sitting inside a case with somebody else’s logo on it.
Seagate
Status: Still manufacturing hard drives
Seagate is the oldest name on this HDD manufacturers list. The company was founded in 1978, shipped its first hard disk drive in 1980, and hasn’t stopped since. It’s one of only three disk drive manufacturers still operating today.
It got there largely by absorbing the competition, picking up Conner Peripherals in 1996, Maxtor in 2006, and Samsung’s hard drive division in 2011. So if you’ve owned a drive under some other brand name in the past thirty years, there’s a decent chance it was a Seagate underneath.
Seagate has historically competed hard on price for consumers, which is part of why its drives turn up so often in external enclosures and prebuilt desktops. It ships slightly fewer drives each year than Western Digital, and comfortably more than Toshiba.
Western Digital
Status: Still manufacturing hard drives
Founded in 1970, Western Digital is the hard drive manufacturer most people have owned something from, whether they knew it or not. Like Seagate, it grew by acquisition, completing its purchase of Hitachi Global Storage Technologies, later HGST, in March 2012. Today it’s the largest of the three by unit shipments, though its lead over Seagate is thin.
There’s a more recent change that a lot of buying guides still have wrong. On February 24, 2025, Western Digital completed the separation of its flash business. SanDisk is now an independent, publicly traded company again. WD kept the hard drives and is, for the first time in years, a hard-drive-focused company. SanDisk took the SSDs, memory cards, and USB flash drives, and it still sells WD-branded flash storage under license.
Toshiba
Status: Still manufacturing hard drives
Of the three remaining hard disk drive manufacturers, Toshiba is the one most often missing from a list like this one. It became a major player when it acquired Fujitsu’s hard drive assets in 2009, and it has stayed put while nearly everyone else sold out.
It’s a distant third by volume, and the one you’re least likely to have bought on purpose. Buy enterprise or NAS storage, and you’ve probably handled a Toshiba drive. Buy consumer externals, and you may never have seen one.
Samsung
Status: Left the hard drive business in 2011
Samsung built hard disk drives for over two decades before selling that division to Seagate in 2011. Any spinning drive with its name on it that you own today predates that sale.
What the company didn’t give up is flash. Samsung is still one of the largest SSD makers in the world, and its consumer and enterprise solid-state drives are among the most widely used anywhere. When someone asks who makes SSDs rather than who makes hard drives, it’s usually the first right answer.
SanDisk
Status: Never made hard drives
SanDisk has been a flash memory company since it opened its doors in 1988: memory cards, card readers, USB flash drives, and SSDs. It has never been a hard disk company, and it has never built a single hard disk drive.
Its corporate history is where most articles go wrong. Western Digital acquired SanDisk in 2016, and for nine years it operated as a WD subsidiary. That ended on February 24, 2025, when the flash business was spun out, and SanDisk went independent again.
Kingston Technology
Status: Never made hard drives
Kingston bills itself as the world’s largest independent manufacturer of memory products, and that’s the best way to think about the company. It builds DRAM modules, flash storage, and solid-state drives. It’s never been one of the hard disk drive suppliers, despite showing up on plenty of hard drive brands and HDD brands roundups.
Its reputation in business environments rests on encrypted USB drives and on data center SSDs built to protect in-flight data when the power cuts out. If security matters more to you than raw capacity, Kingston is a sensible place to look.
Crucial (Micron)
Status: Never made hard drives; consumer brand ended in 2026
Crucial is Micron’s consumer brand, and for years it was one of the easiest recommendations in storage: well-priced DRAM and SSDs straight from one of the few companies that actually fabricates memory.
That changed. On December 3, 2025, Micron announced it was exiting the Crucial consumer business to redirect supply toward data center and AI customers. Consumer shipments continued only through the end of its fiscal second quarter in February 2026. Micron has said it will keep providing warranty service and support for Crucial products.
So your Crucial SSD still works, and it’s still covered by warranty. You just can’t buy a new one at retail anymore. That makes it the most recent name to exit a consumer storage market that keeps getting smaller.
Hewlett-Packard (HP)
Status: Left the hard drive business in 1996
HP is the entry that surprises people. It really was a hard drive manufacturer once, through its Disk Memory Division, and it built some ambitious hardware along the way. The 1.3-inch Kittyhawk drive from 1992 is still a favorite among storage history buffs.
Then in July 1996, HP announced it would stop manufacturing disk-drive mechanisms and close the Disk Memory Division. The company said its share of the disk-drive market had been declining in a very tough environment, and that it would focus instead on extended storage: tape drives, libraries, and recordable CD technology.
HP still sells plenty of storage today, including enterprise arrays and external drives. But the mechanisms inside them come from the three companies at the top of this list.
Why the Hard Drive Manufacturers List Keeps Shrinking
Thirty years ago, this article would have listed dozens of hard disk drive manufacturers. Most of the hard disk companies that defined storage in the 1980s and 1990s don’t exist as independent businesses anymore.
The reason comes down to how difficult these things are to build profitably. A read/write head flies over a spinning platter at a height measured in nanometers, close enough that a single speck of dust is a catastrophe, and manufacturing to that tolerance takes fabrication plants that cost billions and only pay for themselves at enormous volume. Meanwhile the price per gigabyte fell year after year, and flash memory took the high-margin consumer business away. Companies that couldn’t reach the necessary scale sold their drive divisions to companies that could. HP said more or less exactly that on its way out in 1996, and Micron gave a version of the same answer in 2025 when it redirected Crucial’s supply toward AI demand instead.
What’s left is three hard disk drive companies, each of which grew at least partly by buying up the others. It’s a short list, and it isn’t getting any longer.
The split between them is closer than most people assume. The industry shipped an estimated 124.3 million drives in 2025, and the three divided it roughly 42 percent to Western Digital, 41 percent to Seagate, and 17 percent to Toshiba.
Nearly all of that manufacturing happens in one part of the world. Thailand is the center of the hard drive industry, with Malaysia and the Philippines close behind, and Seagate’s Thai operations alone account for close to half its global workforce. That concentration is why a flood or a factory disruption in a single region can turn into a worldwide drive shortage.
Choosing Among Today’s Hard Drive Suppliers
Because only three companies manufacture hard drives, the brand on the label matters less than it used to. Most hard disk drive brands you see on a shelf aren’t hard disk manufacturers at all. They’re buying mechanisms from Seagate, Toshiba, or Western Digital and putting their own enclosure around them. So ask these questions instead:
HDD or SSD?
Hard disk drives still win on cost per terabyte at high capacities. SSDs win on speed, noise, and physical durability, though they fail differently and often with less warning.
Internal or external?
An external drive is a standard internal mechanism in a plastic shell. Sometimes the shell or its USB bridge board is what fails while the drive inside is perfectly healthy, which is worth knowing before you assume the worst.
What is the warranty?
Warranty length is the clearest signal hard disk suppliers give about how long they expect a drive to last. Consumer and enterprise lines from the same maker can differ a lot.
Which product line?
A NAS drive, a surveillance drive, and a budget desktop drive from the same manufacturer are built to different standards and rated for different workloads. This matters more than the brand name, and the next section names them.
Is the data backed up?
Every drive on this page will fail eventually. No manufacturer is a substitute for a backup.
The Product Lines Worth Knowing
All three hard drive makers sell several families built to very different specifications, and the family name tells you far more than the logo does. A single hard drive maker will sell you a drive meant to run a few hours a day, and another meant to spin continuously in a twenty-four bay array, and the two are not interchangeable.
Western Digital
WD Blue for everyday desktop use, WD Black for gaming and workstations, WD Red Plus and WD Red Pro for NAS, WD Purple for surveillance, and WD Gold and Ultrastar for data centers.
Seagate
BarraCuda for desktops, IronWolf and IronWolf Pro for NAS, SkyHawk for surveillance, and Exos for data centers.
Toshiba
X300 for performance desktops and gaming, N300 for NAS, S300 for surveillance, and the MG series for data centers.
Putting a desktop drive into a NAS, or a surveillance drive into a gaming PC, is a far more common mistake than buying from the wrong manufacturer.
If you’d rather have reliability data than opinion, Backblaze publishes failure statistics every quarter from its own fleet of more than 300,000 drives, broken down by manufacturer and model, and makes the raw data free to download. It’s the closest thing the industry has to a public reliability record. The one caveat is that it measures drives running continuously in a data center, which is harder duty than most drives in a home or office will ever see.
Veelgestelde vragen
As of 2026, three manufacturers build hard disk drives: Seagate, Toshiba, and Western Digital. Every other brand selling an HDD is reselling a drive made by one of those three.
Western Digital leads, but only just. Of the roughly 124 million drives shipped in 2025, it accounted for about 42 percent, Seagate about 41 percent, and Toshiba about 17 percent.
Almost all of them are built in Southeast Asia. Thailand dominates the industry, with significant operations in Malaysia and the Philippines.
Many more companies make SSDs than make hard drives. Samsung, SanDisk, Kingston, Micron, Seagate, and Western Digital all sell solid-state drives. The flash memory inside them comes from a much smaller group of fabricators, principally Samsung, SK hynix, Kioxia, Micron, and SanDisk.
No, HP stopped manufacturing hard drive mechanisms in 1996. It still sells storage products built around drives from other manufacturers.
Micron announced in December 2025 that it was exiting the Crucial consumer business, with shipments ending in February 2026. Existing Crucial products remain under warranty support.
Neither one is categorically better. Both build drives across a wide quality and price range, so what you actually want to compare is the model you are buying, not the logo on the label. Backblaze’s quarterly drive statistics are the best public source if you want numbers rather than opinions.
No new hard drive companies have entered the market in decades. The cost of building hard disk drives at scale is high enough that the barrier to entry has only risen over time.
When a Drive Fails, the Manufacturer Is Not the Question
Knowing who makes hard drives helps you buy well. It doesn’t help much at two in the morning when a drive stops mounting, and the only copy of something important is sitting on it.
DriveSavers recovers data from every manufacturer on this list, from current HDDs and SSDs to drives built by companies that don’t exist anymore. If you’re shopping for a replacement because your last drive failed, contact DriveSavers first and find out whether your data is recoverable. Do that before you do anything else with the old drive.
