| ArsTechnica recently ran a few articles that look at the fusion drive in depth, their main article is here: http://arstechnica.com/apple/2012/11/achieving-fusion-with-a-service-training-doc-ars-tears-open-apples-fusion-drive/ It's worth reading, the main thing to note is that until the SSD part of the fusion drive is full (which I think is 768 gig) then only the SSD is used, so the speed of the system will be the same as if you had a SSD only. The fusion drive will be slower than an SSD-only system when you are accessing files that are stored on the normal HDD, which will happen if the SSD is full and if you haven't accessed that file recently. Frequently accessed files are automatically copied from the HDD to SSD - it's all in the article. -Chris -----Original Message----- From: Teddy Gage [mailto:teddygage@gmail.com] Sent: Wednesday, January 9, 2013 09:23 AM To: 'After Effects Mail List' Subject: Re: [AE] iMac SSD or Fusion? I have a 256gb Vertex extreme in my windows workstation as OS drive, so no, not my first experience. The fusion drive is great but falls somewhere between a HDD and an SSD in terms of speed. The most notable difference is that my laptop boots much faster, but it is no SSD in terms of file transfers. I get maybe 10 MB/s more on long file transfers than a pure HDD, but even that can make a difference. However my girl's macbook air with an SSD boots in less than half the time into the same version of snow leopard (maybe 10-15 seconds?). And file transfers are at least 2x faster. I'm starting a new long term freelance job so I may justify the purchase of a new quad core retina mbp...
