I bought a new iMac last summer and went with the 1TB Fusion drive. It works well, but is already full. Is it possible to upgrade the size of the fusion drive myself? Can I buy a 3TB internal drive and just swap out the existing 1TB drive?

Does anybody have experience with this or are there any blogs you know about? I have been doing lots of research but haven't found anything.

    Thanks for the link. I have replaced a HD before, I am mainly interested in upgrading the standard HD component of the fusion drive, to give me more space. Is that possible? – Wes Apr 17 '14 at 21:28
