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.

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.
Holy fuck can you imagine how long it would take to re-stripe a failed drive in a z2 array 😭
Not a clue. Care to eli5?
When you are running a server just to store files (a NAS) you generally set it up so multiple physical hard disks are joined together into an array so if one fails, none of the data is lost. You can replace a failed drive by taking it out and putting in a new working drive and then the system has to copy all of the data over from the other drives. This process can take many hours to run even with the 10-20 TB drive you get today, so doing the same thing with 140 TB drive would take days.
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…
Is there a Lemmy community for trading surplus hardware yet?
I have a pile of HDDs and servers that I no longer use. I’ve transitioned almost all mine to 20tb+. I might have 8 or 10 4tb REDs laying around. They’re old, probably have thousands of power on hours in the smart data though.
I set up a community on midwest.social and the lemmy.world one is dead (because I’m in the midwest) !homelabsales@midwest.social
Right on!
I don’t know if there’s a hardware trading community yet. I think one challenge is simply how lemmy seems to aim for more general anonymity than reddit, and the DM system isn’t really used to my understanding. (Except by “that fediverse girl” LOL)
Establishing a sense of reasonable trustworthiness to thwart bad actors might take some work.
