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.

Okay. I want total honesty here. How many of you could actually fill that thing up?

[–] alekwithak@lemmy.world 19 points 4 months ago

Archive.org, Anna's archive, Jan 6 footage, Epstein files, there's plenty to back up.

With useful stuff? Never. With random bullshit I think might be useful some day if only I find the time? Easy

[–] suzune@ani.social 4 points 4 months ago

... or be able to backup it?

No sweat, try mirroring a private tracker and you'll very quickly run out lol. You need a couple of petabytes worth.

The real problem is the price of HDDs not going down due to lower production in light of SSDs.

I fully expect WD to drop this as some stupidly expensive SAS drives that almost no consumer will buy. They should at least apply the dual heads for speed tech so we get faster HDDs for the same price.

I have a lot of Linux IOSs which are definitely not VR porn. I have 200TB total including parity disks, and 150TB usable. It's a real pain in the ass to maintain so many disks, and the power bill isn't fun either. I'd love to replace them with fewer disks.

I remember Mac OS X having an issue with its mail app awhile back that would create massive log files continuously that would keep generating until they filled the entire drive. You would have to boot to a recovery partition or such because the OS partition wouldn't have enough room to expand/boot and remove them and fix the issue.

Imagine having 130 terabytes of invisible log files

keep the OS partition like 4tb and make a separate partition for the pirated movies
