First post so hi there! I have another iMac in the house that needs to be backed up before going for its' hard drive recall, and also the drive on my late 2006 17" iMac has filled up rapidly since I took up photography so I need to think about storage. I was just going to pick up a cheap external hard drive but now my head is spinning from all the options and I can't decide whether to a) go ahead and buy a cheap USB backup drive b) spend more on a firewire equipped external HD (2TB WD My Book Studio) c) replace my internal drive with a bigger, faster one (Western Digital Blue?) d) give it an internal SSD drive instead maybe plus external I'm truly lost! I'm aware that the old iMacs hardware is limited and won't see all the performance gains of an SSD, so I'm wondering if a newer HD might be just as good for a little day to day performance upgrade? (The RAM was maxed to 2Gb just after I bought it.) I was thinking WD Black but I read they run too hot. This would also be the cheapest option. If I get a cheap SSD I imagine I'd need an external drive for storage. Would USB 2 be too slow for the /User folder?
