In recent days I've managed to destroy two internal hard drives... Both my own lenovo thinkpad T410 and within a fortnight my father's lenovo ideapad Y450... I think I spurned the harddisks by sitting them on the leather arm of the couch for prolonged periods (I recently discovered breaking bad) and they over heated and made mush of the internal hard drives.
So I guess my question is... I recently discovered the joys of Ubuntu Live USB where I could install packages onto my passport (400GB) and persist the install across sessions. Just wondering if there's justification for ignoring the internal hard drive altogether and just using the install on my solid state drive? I understand there may be hardware issues with this but if people are doing this what would be the best SSD to use for this?
