  1. Thanks for posting the vid.
    It's good to see a straightforward review from a uk user. I'm looking to buy the same model that you've reviewed so I will be interested to see what else you have to say about it.

  2. I bought the same model as your, but my question is: when I ran the black magic disk speed on the fusion drive, I got around 700-800mbps like your in the first time, but when I left it running without stopping it, the second time the drive slowed down to 70-100mbps, and third time it ran back to 500-800mbps speed. I feel likes the speed of the fusion drive is not stable. Does it happen the same to your iMac? thanks

  3. the geekbench result doesn´t seem to be apropiate – I have an late 2012 imac 21.5 inch, with a 2.9 quad core i5, 8GB of Ram and 1 TB Fusion drive, it scores 10500 points on geekbench 4. I have seen other benchmark here on the internet for the exact same imac you have and those show geekbench results at about 14000 to 14500 –
