The article is basically correct on the details, but like you stated, it has a terribly negative and biased tone. It seems like his issue is more with the price and compatibility of SSDs than anything with Fusion Drive. I'm not too familiar with the specifics of the situation, but it pre-dates Fusion. Starting on the MacBook Air a few years ago, they started using a proprietary connector with a smaller form factor for SSDs. This has since expanded to their other laptops and iMacs. At the time the SSD drives were significantly smaller than what I saw on the market, but that doesn't completely explain the proprietary connector. This is probably the biggest reason I'd consider other laptops when it's time for me to upgrade...so maybe it's good he's making noise about this. As for the complaints about pricing, again I haven't followed details of SSDs too closely, but I know SSDs vary in price widely based on performance/quality--and the $80 SSD he links to has very mixed reviews. An inflated price is in line with Apple's spinning disk and RAM upgrades, so it's not surprising they'd overcharge. He also fudges some numbers by repeatedly saying Fusion Drive costs $450 ($200 because you have to upgrade from the base model and $250 for the SSD) but doesn't mention at all that the upgraded model doubles the spinning drive (500GB to 1TB) and gets you a i7 instead of an i5 processor (I was looking at the Mac mini). At least for laptops, I think his suggestion of using an external SSD drive "will experience nearly every advantage that Fusion Drive has to offer – at a fraction of the cost" is absurd since the first thing you'd put on the SSD would be your OS--which I wouldn't want on an external drive.
