I want to forget about the questions of reliability, heat, sound, outdated technology, benchmarks, and start a discussion about the difference between SSD and Fusion Drive from a real-world user's perspective. As every user is different, I wanted to categorize each user and have everyone discuss which one is more suitable for each. 1. Casual User - Web browsing, watch movies/youtube, listen to iTunes 2. Casual Gamer - play games such as WoW, LoL, CS:GO, Rocket League, SC2, etc. 3. Hardcore Gamer - play games such as FFXIV, Crysis, Battlefield, Call of Duty, etc. 4. Audio Producer - produce music using Logic, Protools, Cubase, Sibelius, etc. 5. Amateur video producer/editor - produce youtube videos, homemade videos, not very long. 6. Professional video producer/editor - produce 4k videos, feature length films 7. Web designer 8. Graphic Designer - uses Photoshop/Lightroom extensively 9. Software engineer - Mac/iOS app coding in Xcode Who amongst these categories of users would see a significant, measurable difference in SSD over Fusion, and why? Assume cost is not an issue and that no external drives are being used. Assume 3TB Fusion drive (with 128GB SSD) vs. 1TB SSD. The reason I want to ignore cost is because too often advice is given "If your budget allows for it, get the SSD, otherwise get the Fusion," making it seem like the SSD is 100% the better choice. I don't think this is right, because there are groups of people who can benefit from the extra 2TB in the fusion drive, over the 1TB SSD. However, no one wants to sacrifice real-world performance to get that extra 2TB. So what is being sacrificed?
