configuring external ssd as storage for late 2013 imac 27

I do not need the best and the brightest and fastest anymore - however shelling out a couple of grand for a new machine isn't something I want to do or even need to do. It is slowing down and cannot or will not upgrade to Catalina.and I 'think' that the Mojave upgrade was a mistake.

If external storage is not desirable and you want more capacity, go Fusion.MY late-2017 27' iMac - 3.4 GHz intel Core i5 with 8gb of RAM and 1Tb SATA HD has outlasted any computer I've ever owned - MAC or PC. It would be a false economy to buy a $2000+ computer, only to risk damaging it by opening it up for the chance to save $50. I will also note that opening up the current iMacs is more difficult than in the past, due to the laminating process on the screen to reduce glare, parallax and weight. For example, OWC sells compatible SSDs for the MacBook Airs ( ) that may work, but I don't believe anyone has specifically tested it. You're not going to find a compatible PCIe SSD for any less than Apple's upgrade cost. It will give the most noticeable performance boost of any possible upgrade on the iMac, unless you prefer to spend the money doing an all-SSD setup, which will still be very, very fast.

The $200 for the fusion drive is expensive, but not insanely so. You could of course get an external USB3 drive to provide large storage if you prefer, or even get a USB/Thunderbolt external SSD. You should get the 1TB or 3TB Fusion drive configuration if you want more than 256GB of storage and don't want a larger SSD. The PCIe card used in the new iMacs is the same (custom) stick-like form factor Apple uses in their other products. The PCIe flash storage will be faster than the SSD, but how much you'll notice that in the real world is questionable.
