Hello, I would greatly appreciate some help with speeding up my iMac for editing video with FCPX. I've got 1080P footage that I'm trying to edit and I keep getting dropped frames and overall I would like to speed up my system with an SSD like my MBP. I know that my speed bottleneck is my internal HD and external USB hard drives. I'm not needing to work with all of the data at once, the external drives are more for archiving the footage but I will occasionally need to work with footage from them. I'm not a professional, I'm helping out a non-profit with training videos - so price is definitely a consideration! Here is my current situation: 2011 3.1GHz i5 27" iMac / 16GB Ram / 6970M 1024 MB / 1TB HHD at 50% capacity and 110MB/s read/ Thunderbolt, USB 2/ 2 external displays plugged into the thunderbolt ports. Several 2TB My Book Studio hard drives (capable of USB 3) @ about 65MB/s read & write on USB 2 (Horrible speed, I know...) The options that I have looked into are: ($199-349) Getting a LaCie rugged thunderbolt external SSD to run OSX from and use internal HHD as more of a scratch disk. - LaCie portable has only 1 thunderbolt port so I would have to ditch a display, It's also bus powered so it's not quite as fast as other options. ($200) Getting a Belkin Thunderbolt Express Dock so that I can tank advantage of USB3 on my existing HDs - Not sure how much of a speed improvement I would get and I would still want to get some sort of SSD to run the system from. ($490) Taking my iMac to an Authorized Service Provider to add an OWC 6G SSD into the empty bay to run OSX from and the HHD as more of a scratch disk. - Half the cost is parts and labor, can't swap easily if the SSD fails or I get a new computer. ($710) Getting something like the OWC ThunderBay IV and running OSX from a OWC 6G SSD and eventually putting in more HDs and possibly a 2nd SSDs to use as a scratch disk. - Expensive and I'm not sure about the speed of a single SSD in the ThunderBay. (I'm assuming that I can boot OSX from the ThunderBay) ($1500-2100) Buying a newer iMac that has an SSD. - The most expensive option, I don't want Fusion drive, and I would have to give up the dvd drive. Any thoughts on speed performance and cost of the options? Best bang for the buck? Thanks!!!
