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.

If you were to ask me a year ago I'd tell you that HDD's would be the next dead storage medium but now SSD's cost more then I spent on my rig and HDD's are pushing 140 TB's

I just looked up prices for servers we sell out work.
They saw a price increase of 47%.
The SSDs and RAM saw an increase of about 25% and ~150% respectively.
Absolutely ludicrous and BS (ironically both the price and available stock increased. So it's just preying on the market instead of an actual shortage lol)

I wonder if tapes make any sort of 'comeback' to the consumer market.
