Fusion drive is a complete sham and useless in real life. It looks good in benchmarks because they are just doing little tests that don't fill up the hard drive so of course it will have the same speeds as an SSD. But in reality once you fill up even a small portion of the total space most of your data will be on the normal HDD which by the way is only 5400 rpm anyway. It is pure novelty and likely more dangerous because it means if even one drive fails all your data is gone. Twice as likely for disaster. Avoid it at all costs. This is not an opinion it is fact.
