Hi, as you may have read from a previous post, I've ordered my MBP with 128GB SSD which is prob a little on the small side. I'm going to use it with iCloud for photo and important file backup but also would like an external drive to store video content that's waiting to be edited.. Just been in the Regent Street store and note that the Time Machine HD's are pretty expensive.. What do you guys recommend as an external HD with fairly swift read/write times? Maybe the Time Machine HD's are expensive for a reason? I'd like it to be a wireless network device which can be written to wherever I am in the house.. Rob.
