I thought we were already in that situation. Cache is king.
- thfuran 11y agoThe real change is that with increasingly performant and large SSDs, it's becoming reasonable to have main storage for which random access is orders of magnitude faster than HDDs will ever be. Still much slower than cache, but a few orders of magnitude here and there are likely to shift what optimal strategies are.
