Reticulated gas is charged by the kWh here in New Zealand. The meter may well be calibrated in m³ (I don’t have gas at home, so I don’t know for sure) but all pricing is energy, not volume.
For bonus points, if instead you buy your gas in cylinders - a pair of 45kg (~100lb) cylinders is a common installation for houses without piped gas - those are sold simply by the unit. The best conversion for that I can find is one energy retailer describing one 45kg cylinder as 2200MJ (611kWh).
I expect this is one of those things that is overall horribly inconsistent depending on where you live.
Assuming you’re not talking about this article’s 7.68TB drive and not the mentioned 61.44TB one, actually far less than you’d think.
Solidigm’s equivalent (https://www.solidigm.com/products/data-center/d7/ps1010.html) goes for between $1000 and $1500 USD for the same 7.68TB capacity: https://www.serversupply.com/SSD/NVMe/7.68TB/SOLIDIGM/SB5PH27X076T001_394195.htm
(And performs similarly, 14.5GB/s R / 10GB/s W, vs 14.6/11 for the one in the article).
