Hello! I’m new here, well, new to posting - I’ve availed myself of the knowledge here for some time. Thank you all, by the way! I have a question I just can’t seem to find a clear answer for, so I’m posting here. I’m about to purchase a new iMac 21” (most likely refurbished) I’m keen on a SSD drive but due to price I’m looking at the smaller 256GB version. I do photo editing and songwriting/recording in Reaper and the files are large. What I’d like to know is: if I were to use the internal SSD drive for the OS and my programs, would using a traditional hard drive connected via Thunderbolt be fast enough to store my files for active projects? I’d like to avoid creating a big bottleneck that would negate the speed of a SSD drive and souped up RAM. Your thoughts are much appreciated!
