I don't understand what that means. 70k per what? 120k per what? What is a "hit"? A read operation?

Looking at the data sheet for a contemporary Sony CD-ROM mechanism

◆ Service life of feed motor

The current consumption of feed motor must be less than initial value plus 30% after 50,000 cycles. (1cycle : innermost track → outermost track → innermost track)

◆ Service life of limit switch

The contact resistance must be less than 100mΩ after 50,000 cycles. (1cycle : innermost track → outermost track → innermost track)

◆ Pick-up slide operation

The pick-up should operate perfectly after 50,000 cycles. (1cycle : innermost track → outermost track → innermost track)

I would interpret it as completing the game requires 120,000 disk read operations, but the CD drive may fail after just 70,000 read operations.

70k per lifetime of the CD drive. 120k per complete playthrough of the game. A hit is reading from the CD.
