So at $8,000 for 160GB, we now use ultra expensive SSD as an alternative for more cheap faster RAM?
You do remember why swap was invented - because memory was scarce and disk was cheap.
- fragmede 16y agoViolin Memory does just that (no relation) http://www.violin-memory.com/products/dram/ http://www.violin-memory.com/products/dram/ I'm not finding it on their page, but they had one product that was 1TB of ram, backed by a 1 TB disk with a backup-battery. You get super fast storage, and if the power went out, the TB of ram would get saved to disk.
- moe 16y agoYup, I second violin. They have it about right when you're really starving for IOPS. It naturally comes at a price. But last time I checked the violin's were a much more natural next step after maxing out local SSDs and RAM than the FusionIO devices (which seem more like a stopgap-solution rather than a scaling path).

- wedfvgberfgbh 16y agoYes thats a good caching scheme for a harddrive. But my point remains. I have say 1Gb of ram, I need more memory, so I turn on swap, swap is slow so I go out and buy a super-expensive SSD hard drive instead of just buying more ram.
