To be fair, enterprise SSDs (particularly U.2, U.3 and E.1L) have had their own availability issues for a fair bit now, particularly the latest NVMe PCIe Gen 4 devices. However, the problem there isn't cryptocurrency, but hyperscalers having had exclusive periods to buy directly from the manufacturers. Which they have. At immense scale. Some drives announced nearly a year ago are only now hitting the retail and VAR channels.

High-speed DDR4 ECC memory (DDR-3200 in particular) can also be tough to come by. A fair number of VARs actually limit quantity (usually to 20 modules per SKU), since it's so tough to get. Again, not due to crypto mining, but because of hyperscalers.

It's just a spike, the price will come back down quickly as total stored space increases and makes further "farming" even less competitive. Just consider how quickly the projected rewards are dropping, e.g. at https://chiacalculator.com/ or the XCH/TiB chart at https://www.chiaexplorer.com/charts/xchTib (same site as OP).
