Good ideas Igor. I have always used Seagate HDD's but never really looked at reviews. I'll do that
iMac is USB 2 Just wondering now if i should copy them to my HD then to the new external that way they will be on my time machine drive aswell (ie 2 drives). I have alwasys in the past had two externals hooked up to the computer, plus i will still have the CD/DVD's Dave Daev On Thu, Dec 8, 2016 at 1:13 PM, Igor PDML-StR <[email protected]> wrote: > > Zos said what I was going to say. > You will not feel a difference between 7200 and 5400 rpm drives in the > transfer rate when you are backing up photos. > > The main situation when you feel the difference is in the "random access", > when the system/program accesses many small files.
