While I look forward to that future, realistically nvm ram is going to be at least as pricey as ssds or volatile ram, which means that a more likely in between approach that tries To minimize the amortized io between fast nvm (our ram replacement) and cheap and relatively slow nvm (hd or ssd).
- guard-of-terra 14y agoIf it would cost as SSDs do, it's pretty simple then: you mount NVM as /, and /var & /srv are still on disk. All your programs lose start-up time and most of swapping. If it would cost more, you can use it as a persistent block cache (that survives reboot), but it doesn't make much economic sense since nobody is willing to pay money for just faster start-up and warm-up after reboot. If you have 8G of NVM, you could just read 8G off disk in something like 30 sec and be settled with regular RAM.
