Hi all, based on different users' experience, I recon installing an internal SSD SATA Drive into a iMac 27'' (2011) is a pretty painful experience... I've just done the operation on my macbook pro 2009, and now this older model feels faster even than the 2 year younger Desktop. Beside the price, is an external Thunderbolt SDD SATA drive a good option for the 27'' iMac ? I mean to use it as the boot drive... Any experience ? Ideas ? Thanks !!
