Appreciate lots of SSD posts on here, but my question is more of a general one and would appreciate your opinions. I have just got my new Late 2015 5k iMac i5/512 SSD/395 (Replaces my now very old early 2009). I have always kept my iTunes library on an external USB2 1TB spring drive. I was considering treating my new iMac to a new external drive.... Samsung EVO 850 (or similar) in a USB3 casing. I don't mind spending the cash but i am starting to think it maybe overkill. I basically only use my external for my iTunes (100gb) and as a secondary backup location for my photos and important docs (Crashplan). Not sure i am going to see a huge benefit from the upgrade - wonder what you guys who have an external SSD for iTunes think?
