Why do you need to install each game before you can play it?

Why don't games come on tiny hard drives that you can just plug in instead of disks..


Points to 3DS and Vita

This isn't the norm for consoles since it would cost a lot more to manufacture each game as a 64GB SD card

PS4 or Xbox... Why not Zoidberg?

Seriously doubt that I know a lot goes into it and it would cost more then a disc but you can buy 64 gB flash drives for like 20$ It doesn't cost much to manufacture these so I can see this as a possibility. This would pretty much do away with cases which is a big deal to some people

Disk Read speed is not the problem. If that were the case, they could easily spend a little more and put in the fastest BD drive that has read speeds that would suffice.

The problem is, Optical media has horrendous random seek times. The motor has to move the laser to the circle the data is on. It's simply not fast enough.

Hard Drives use a similar concept but at a significantly faster mechanical operation method. Random seek time improves ability to stream by not needing data to be written in a particular pattern.

Before the PS3 and Xbox 360, game data was replicated many times over due to the necessity to stream and not require the optical drive to move around attempting to locate data.

Ps3 and 360 started requiring data to be cached so that it didn't have to be optimized in this way since games got bigger and more data would need to be replicated.

The PS4 and Xbox One games are getting larger and the ability to install means they don't have to optimize the data location and duplicate data to stream effectively.

Throughput is not a significant measure of the performance of a hard drive for applications such as games. For backup purposes where all data is written sequentially and read sequentially, there are even tape based solutions that rival the throughput of SSD drives. However, using a tape drive for application use would be horrible and using optical disks for all game data would be equally horrible.
