Want to speed up my MBP Early 2011 13". I'm worried about complex operations such as partitioning, OS reinstall etc that I need to do using a mixed SSD/HDD config, and don't want to invest into a big SSD (no reason I need only to speed up OS and app launch times). Idea can be to have a SSD as cache so to transparently speed up the whole operations. There are any caching sw I can use to emulate Apple Fusion technology? As I read Intel RST can't be used on Mac, and can't find any other solution than some geeky config or this http://ssdcache.com/ that's in beta since 2012. Any other option? Will be nice some USB/Thunderbolt key-size SSD that can be plugged-in and forgotten, without the need to optical bay installations etc.
