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.

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

Are you in Europe by any chance? :)

[–] brygphilomena@lemmy.dbzer0.com 5 points 5 months ago (1 children)

Ah, no. Sorry. Midwest, USA.

No apologies needed, I'm not even OP :) it was just a long shot :D

[–] MonkeMischief@lemmy.today 1 points 5 months ago (1 children)

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.
