Yes, it has a 2x CD drive, which is used at 2x speed. Loading times aren't exactly cut by 2 when comparing to older models due to fixed delays caused by CPU data copy.

NEO-GRC2-F

See optical pickups

Sanyo LC89513 CD host chip, able to do 4x speed by the way:

Z80, its RAM and 1MiB PCM DRAM:

Same weird voltage limiting power supply circuit:

System ROM: TOP-SPD.

Unpopulated fotprint for CD drive chips:
