Well, you do not need to get a CF to have SSD on a Mac. For a little more than a 8GB CF with an IDE Adapter, you can get a IDE/PATA IDE, and connect that to the IDE to SCSI Adapter. KingSpec has 4 to 8 GB PATA-SSDs for under $30 on eBay. I recommend getting a 1.8in unit instead of a 2.5in as they are a bit less. It does not matter if it says its for a "Thinkpad 4-something" series, that particular ThinkPad only uses 1.8 hard drives and a 2.5in hard drive can not fit in it. Other than that, they are the same electronically and the IDE Connector on it is the same as a 2.5in. On eBay search for "IDE PATA SSD." Then it's just search for IDE to SCSI adapter to connect to it.

Problem with the 1.8in SSD - the screw holes do not line up with a 2.5in drive frame. So some hardware hacking is needed. I use 2-sided tape for that.

Ebay has some SCSI SSDs but at $500 plus each, that thing better serve me breakfast in bed and cut my toenails when they get too big!

Consider this as an option.
