Honestly, even I’m in this boat now. I have 4 computers in my house (2 desktops, 1 fileserver, 1 laptop), and I bought 2 different 4TB NVME drives over the last couple of months to prepare for what I think will be, and so far it’s turned out as I’ve thought since prices have gone up and up, the next shortage and/or price hike scenario for the next couple of years. I pray none of my RAM dies, even though at the moment it would all still be within the warranty period except for my fileserver. FWIW I also keep a spare 1000w power supply around in case any of those die too, and I would not have wanted to buy my Thermaltake GF3 for a spare at today’s price of $230+ (I got mine for about $150 after taxes) either.
Also, it’s sad to read above that Samsung exited the 2.5in SSD market. Crucial and Samsung have been my go-to brands for 2.5in SSDs for like a decade at least. Thankfully I’m full up on 2.5in SSDs of all capacities and generally have been phasing those out for NVME storage. However, for pure storage, there are only 2-3 NVME slots on any given motherboard and there are typically 4-6 SATA ports, not to mention older systems can’t use NVME at all (I guess some can with a PCIe slot adapter if the BIOS supports it).
