Western Digital details 14-platter 3.5-inch HAMR HDD designs with 140 TB and beyond (www.tomshardware.com)

Because nothing says "fun" quite like having to restore a RAID that just saw 140TB fail.

Western Digital this week outlined its near-term and mid-term plans to increase hard drive capacities to around 60TB and beyond with optimizations that significantly increase HDD performance for the AI and cloud era. In addition, the company outlined its longer-term vision for hard disk drives' evolution that includes a new laser technology for heat-assisted magnetic recording (HAMR), new platters with higher areal density, and HDD assemblies with up to 14 platters. As a result, WD will be able to offer drives beyond 140 TB in the 2030s.

Western Digital plans to volume produce its inaugural commercial hard drives featuring HAMR technology next year, with capacities rising from 40TB (CMR) or 44TB (SMR) in late 2026, with production ramping in 2027. These drives will use the company's proven 11-platter platform with high-density media as well as HAMR heads with edge-emitting lasers that heat iron-platinum alloy (FePt) on top of platters to its Curie temperature — the point at which its magnetic properties change — and reducing its magnetic coercivity before writing data.

We've come a long way:

That was my first USB thumb drive.

IIRC that was 5 mb. It weighed about 2000 lbs

Fee-fi-fo-fum.

In a pinch the drive can also double as a flywheel battery.

Can somebody do anything with a normal consumer in mind these days? 😭

Not until somebody shuts off the investor money faucet for AI. Then they'll come crawling back — although inevitably not until after they go whining to all the world's governments about wanting a bailout.

But hey, look at the bright side. We've already had the cryptocurrency mining boom and bust, and "AI" boom and soon to be bust. There's still time for some idiot to invent the next tech scam fad which will conveniently require a shitload of hardware for no recognizably useful purpose.

No, and it's by design.

You're gonna lease a tablet and use cloud-based storage services and like it.

The dystopia is here.

Okay cool, cool, so does this mean ridiculous data centers will use these things, and then can I get another 4TB RED for my NAS so I can fit my whole life on a mirrored total of 8TB without paying 8x what it's worth, please?

Thaaaaanks...

I just hope smaller sized drives become cheaper. The word "hope" is doing a lot of heavy lifting here.

Ten years from now...
