Particularly interesting is the possibility of using a SSD as a cache for a HDD just like the Fusion Drive in the recent iMacs (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/plain/Documentation/device-mapper/cache.txt?id=c6b4fcbad044e6fffcc75bba160e720eb8d67d17 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux....)
Reviews were quite positive of Apple implementation. Has anybody tried the linux version ?
- dsr_ 13y agoI've got flashcache running on a 20GB SSD partition fronting a 120GB spinning disk partition, on a desktop at home. It feels (anecdotal, subjective) as fast as a pure SSD for all normal desktop things. I also ran a small MySQL db through this setup for a few weeks, and that improved noticeably over a single spinning disk, especially when there was IO load from other processes. The install procedure is a little rough around the edges, so I'm looking forward to having that more polished.
