I have late 2012 21.5 iMac with scandalous 5400-rpm HDD (which 5 years later the newest 21.5 iMacs still have...) Since the beginning, I was thinking about getting external SSD, and now with APFS, it seems like best time to finally get to it. Instead of upgrading system I leave it in case as it is on the HDD and when High Sierra comes out I do a clean install on USB 3.0 SSD. Or am I missing something and that is a bad idea?
With USB 3.0 SSD will I get all the benefits of APFS, or is there something with APFS that would make booting from the external SSD not recommended?
Also, any recommendations for enclosures or adapters to connect the SSD externally to USB 3.0? Is UASP something that matters? No thunderbolt, I wanna get this done cheapest way, not sure how much longer I will have to keep this old iMac, hopefully next year iMacs will be all flash. (sorry for my poor English)
