xbox 360 technical question?

[R1 Indy]

Just ordered a used(refurbed) xbox 360 off ebay to replace my old one with RROD!

Just been asked if i want the drive upgrading to LT+3.0 or left stock?

I have no idea what this means, so can anyone advise me?

Thanks,
Matt

It's probably definitely the modern day version of 'chipping' to pirate the war game videos.

Ahh, i will have just the basic then so it doesn't get banned from live.

Thanks
