Q: I'm thinking it would be cheaper to buy the hard drive later and the system now. A friend of mine has an Arcade, and he said it takes a memory card and not a drive. How much memory do they hold and how much do they go for?
A: Yes, the prices for add-on HDD: $100 20GB $180 120GB Honestly it makes more sense to get a model ALREADY with a HDD Lets price compare: X360 Arcade: $200 Headset: $20 Cheapest HDD: $100 $320!!! 120 Gb HDD: +$180 $400 X360 Pro 20 GB $260 With a 20 GB HDD & headset! X360 Pro 60 GB $300 With a 60GB HDD & headset! X360 Elite 120 GB $400 With a 120 GB HDD & Headset! Get a pro or elite besides an Arcade please!
