I’m looking at getting a new 4K iMac. I love the design and the screen looks gorgeous, but I’m a little bit disappointed by the standard 1TB HDD option and the non-upgradable RAM. I would prefer to buy a refurbished model at a bit of a discount, but the odds of finding one with upgraded RAM and storage options is slim. So I will have to compromise, and that brings me to a few questions. 1) I would like solid state storage. This is sort of a dealbreaker as this is one of the main reasons I’m considering an upgrade at this time anyway. What is the performance difference between the 1TB Fusion drive and the 256GB SSD? I’m looking for real world experience or benchmarks. 2) Assuming that I buy a model with an SSD (or Fusion drive, if that’s sufficient), is 8GB of RAM sufficient, or should I seriously consider investing in more? I typically max out the RAM on my machines within a year of purchasing them which tends to help extend their life a bit, but if that’s not an option on this iMac then I’m worried about shooting myself in the foot by not taking this option while I can. Will the solid state storage will be sufficient to handle any future RAM deficiencies? Thanks, and if these questions are too common or easily answerable, please point me in the right direction. I would very much appreciate it.
