At some point, I hope to see the lines between RAM and SSDs dissolve, such that the OS can just use a portion of the SSD for RAM.

- Someone1234 12y agoUhh, unless SSD technology changes significantly that line is a long long way off. SSDs are orders of magnitude slower than RAM. For example assuming a 2 GB/s speed is legitimate, RAM is over 22 GB/s. Plus RAM can be written and re-written without any wear, whereas SSDs have a max-write limit.
- ch 12y agoRight. Plus when you power off RAM ... Oops!
- pstuart 12y agoI think it's supposed to happen with these: http://en.wikipedia.org/wiki/Memristor http://en.wikipedia.org/wiki/Memristor
- Tloewald 12y agoHP is working on a new architecture based on computers with just a buttload of persistent RAM, but so far it's vaporware.
- walterbell 12y agoSupposedly they will never sell this computer, only renting access as a "fast cloud".
- icebraining 12y agoIsn't that called "swap"?
- Someone1234 12y agoNo. Swap or paging is unused RAM "saved for later" (to free up real RAM space). It is never accessed or modified directly from processes except to push it back into RAM when a process requests a memory region which has been paged.
- gabriel34 12y agoI would think the recent historical tendency is to have more cache levels, not fewer. This would only happen if the cost of storage loses its sensibility to speed.
