Dell is selling Xbox 360 Hard Drives for $40 off. This sale is in the US and it might be in the UK to, I haven't checked. The Hard Drives are being sold for $119.99. The sale only has 4 days left, (in my opinion) it is a good deal and is worth it. (Technically its $30 off as they sell them for $159.99 instead of $149.99) Link
It’s still a lot for a 120gig hard drive even with $40 off, but not a bad deal as 360 hard drives never usually come down in price from what I’ve seen. I should get one at some point, I somehow manage to keep a few gigs free on my 20gig without installing any games.
Now that I have a 120 gig that came with my Elite console, I can't believe I ever got by with a 20 gig. I think I have at least 20 gigs used by now.
If you delete demos and don’t install games you won’t actually fill 20gigs up with just saves and DLC, well I haven’t yet
i have a 20 gig hdd and its been good so far. i dont think i need tht much space unless u dl alot of dlc or demos and dont delete them.
