Why don't Blu-ray players use SSD/HDDs?

Anyone know if there is a technical/practicality reason why Blu-ray players don't utilise SSD/HDD to copy the entire disc as it plays rather than constantly spinning the disc?

Playback from a drive would avoid read errors/difficult layer transitions that always reading from the disc causes and would mean that the disc only had to be spun up during the beginning of playback.

You can still require a disc check to permit continuous playback so I don't see any piracy issues.

Anyone any idea why this isn't done?

Because there'd be little to no point, on top of greatly increasing the price of the player and greatly reducing the convenience/ease of use.

You'd rather wait 40-50 minutes to "install" the film to some kind of in-built storage before watching it? And then presumably have to manage what was stored on the drive when it got full?

Streaming off the disc in real time isn't so unreliable that it would warrant this sort of thing.
