My hard drive is failing on my 2011 iMac 21 inch. I am in the middle of a few projects that I do not have the leeway to be down without my iMac for a day. I have backups of everything but my biggest issue is my iMac is taking a huge performance hit because of this. I already wiped it clean and used an utility to mark bad sectors but it is getting progressively worst. I was thinking about using the Lacie Esata hub to hookup an esata drive to boot off or even the Buffalo Thunderbolt Mini Station Will this work as a solution until I caught up on my projects and have time to have it repaired? Is there any problems with doing this and using Parallels also? Any feedback or input is appreciated.
