I'm going to order an iMac in the next couple of weeks... wondering between the 2TB Fusion drive and the 512 gig SSD. I've had nothing but SSDs in my Macs for years, so I'm a little hesitant about going to the Fusion Drive, but the Refurbs I'm looking at that have what I want have that instead of a decent-sized SSD. I can add a Samsung 850 Pro 1 TB SSD for $300, which makes it more cost-effective to replace the Fusion Drive with one than to spring for the version with the 512 SSD already in it. BUT... if the Fusion drive performs decently, I'd just keep it. Thoughts? --- Post Merged, May 24, 2016 --- And so after I posted this, the Similar Threads showed me a thread just like mine, so I read it... question pretty much answered now. I'll get the Fusion drive and plan to replace it with the 1 TB SSD. I have a 4TB ext USB3 drive for less frequently accessed stuff.
