Hi all, I've been closely following this forum and the news and like many of you patiently waiting for the new iMac. One thing that keeps puzzling me is whether I should go for SSD only or go for the SSD + HDD option. I am currently on a mid 2007 iMac with 320GB HDD and use an external USB 2.0 disk for movies and other large files. I definitely want an SSD for my OS X and applications but I am wondering if it is better to add an internal HDD for the other files (such as iPhoto database, iTunes, movies etc) or if it would be better to go for SSD only with an external USB 3.0 HDD which became quite cheap again (Western Digital 3TB MyBook Essential 3.5 for less then 150 EUR) So basically I am comparing the PROs and CONs of internal VS external. My main reason for NOT choosing an internal HDD would be durability. Without a HDD in the iMAC that is one less component to break and also less heat. And with the Turbo boost enabled CPUs I would guess that less heat means more CPU power as well. The main reason for choosing an internal HDD would be better performance compared to external. Problem is I do not really know how much better performance. For example if I would be encoding/decoding a 8Gb .avi to a .mp4 and then import it into iTunes, would I notice a difference between an internal HDD and an external USB 3.0 HDD? And finally there is a price difference. External = 3TB for less then 150 euro. Internal is 2TB for more then 150 EUR.
