Sorry to resurrect an old thread. Reading more recent posts about fusion drives, is it still recommended to pay extra for the ssd? This thread makes me believe the fusion drive would be okay for my in laws who just do general browsing, web based games and watch videos.
Go pure SSD's, I doubt APFS is ever going to come to fusion or hard disk configurations with hard disks on their way out and fusion being a compromise for those who have a fixation over wanting to have more internal storage (even though they would be better off with a 256/512GB SSD internally with a external hard disk or a RAID like device such as Drobo which abstracts it all in the form of a single piece of storage). In the day of USB3 and Thunderbolt there is no reason why one needs to have a massive storage setup inside the computer when one can go pure SSD internally and use an external storage device for long term storage once you have completed the project but still want to retain it.
