Today, Rockstar support advised Xbox 360 players not to install Grand Theft Auto V's second "play disc" to their hard drives. Doing so, they suggested, would affect performance.
Fortunately, the same folks at Digital Foundry have already found a solution: If you want to play GTA V on Xbox 360 without the noise of a spinning DVD, install the first disc on your 360 hard drive like you normally would, then install the play disc to a USB thumb drive.
They're sure to point out that your your mileage may vary depending on
your thumb drive, but say that the approach made their lag problems go
away.
See a demonstration here:
The 360 version of GTA V comes
on two DVDs. One is an 8GB "install disc" that you must install, and a
second one is a "play disc" that you use to play the game. (The PS3
version comes on a single Blu-Ray.) As you can see in this video up top
from Digital Foundry,
the 360 version with the play disc installed to the hard drive is
noticeably laggy compared to the off-disc version. It's not a huge deal,
but the lag is present.
