I have a 2011 Mini (mid-tier) that's been getting long in the tooth. Not sure what I want to do next -- probably the 2014 but also considering a 27 inch iMac. I have read a good bit about adding an external SSD as a boot drive to avoid opening it up (it's my only computer, though I do have an iPad I could watch the install video on!) I ordered a: Samsung 850 EVO 2.5 inch SATA III Internal SSD OWC Mercury Elite Pro drive enclosure Since my computer doesn't have USB3, I have it plugged into FW800. While downloading El Capitan after I got the drive installed an initiated, I ran the test and it showed my internal 5400 RPM HD at about 10 MB/s. Ran a test on the SSD and got results in the 80s! Thought I was home free, but I knew the download of El Capitan would affect the results. After all was said and done, and I'm just sitting here with nothing going on, my internal gets between 30 MB/s and 60 MB/s, and the SSD continues consistent in the low 80s. Am I wrong in thinking my speeds should be better than this? I know benchmarks aren't the only indicator of performance, as it does feel like it has more snap, but benchmarks are numbers and that's what we like I'm sure the answer is to open it up but I'd rather avoid that if possible!
