For the xbox 360 arcade do you need to by a hard drive or can just keep buying memory cards?

You don't need a hard drive for the Xbox 360 Arcade. It comes with 512MB of internal flash memory, which is enough to store a small amount of games and save data.

However, memory cards are not an ideal solution. They are:

* Limited in storage capacity: Even the largest memory cards only offer a few GB of storage, which isn't enough for many games.

* Slow: Memory cards are significantly slower than a hard drive, leading to longer loading times.

* Expensive per GB: You'll end up spending a lot of money on multiple memory cards to get the storage space of a hard drive.

A hard drive is a much better option for several reasons:

* More storage space: Hard drives offer much larger storage capacity, allowing you to store many more games and save data.

* Faster loading times: Hard drives significantly speed up loading times compared to memory cards.

* Better value for money: You get more storage space for a lower price per GB compared to memory cards.

Here's what you can do:

* Use the internal flash memory: For a few small games and save data.

* Buy a hard drive: For a better gaming experience and more storage space.

Ultimately, the best choice depends on your needs and budget.
