Hi I am close to buying a Macbook Pro, but am somewhat put off by the memory size 'only' being 128/256GB. I have checked my iMac (which I am getting rid of) and it states that I've used about 250GB of my 500GB. Most of the usage is music, photos and videos. I am a keen amateur so take lots of high res photos, and have only just started keeping video clips of family etc. I was wondering, is it possible to wireless connect the MBP to an external HDD to access my photos when I'm at home via wifi, and also use it to back up via TimeMachine? I'm happy to plug in the MBP weekly or whatever to do backups if needs be, but I would like to keep my photos handy rather than having to go upstairs and plug in. In fact, I'd probably keep the recent/favourite stuff on the laptop. I already have a Seagate 1TB that I use for Time Machine backups at min. So basically, can I hook that up to wifi, partition it to have as part additional storage, part backup?
