Hardmod (modchip or TSOP) has a major benefit over Softmod (Rocky5 method) because it “unlocks” the HDD. The original Xbox’s retail HDD is tied to that specific console, but with Hardmod, you can easily replace it with a new HDD and format it. On the other hand, Softmodding does offer the possibility to upgrade the HDD, but it is significantly more inconvenient, around 10 times more!
