TIL that despite the significantly higher capacity of Blu-ray Discs, the PlayStation 3 shipped with a Blu-ray drive whose transfer rate was only 8.58 MB/s (2× Blu-ray1) to the Xbox 360's 16.5 MB/s (12× DVD2), even being slightly more fair and comparing their DVD read speeds, the PS3 still only manages 10.3 MB/s (10× DVD)!
No wonder it forced such sluggish hard drive installs.
