I'm wondering what the "best" route for me to go is. There's a few options that I know of, like flashcache, dm-cache, and bcache. The question is which of those is better suited to my use case? Also wondering which ones people here use, and what they use it for. Thanks! -- Thomas Fjellstrom thomas@fjellstrom.ca
