sheepdragon: Transfer speed would probably become an issue for some. According to specification, a 2x speed blueray disc has a transfer rate of 72mbps or 9,5mb/s. Installing a 50gb at that constant rate would take about 90 minutes.
There are plans to raise the speed up to 8x. which would lead to a transfer rate of up to 288Mbps/36mb/s. It would still take almost 24 minutes at that constant rate, though.
lukaszthegreat: we started with 2x dvd's right? now how much they are 48? i don't really know.
now new game takes around 10-20GB
five years ago it was 5-8
ten years ago it was how much? 1gb?
50gb matters not. we barely hit 20gb mark and batman only takes 8.
so before we get 50GB we will have blrays 24x and standard 1-3T hdd
Blueray has a maximum rotation speed of about 10,000 RPM, which brings us a 12x speed, which should make it possible for transfer rates of up to 400mbps/50mb/s. Which brings the 50gb install down to about 17 minutes. That's not too bad, as some games do take that much time install. Some probably take even longer.
Hard drive size is not an issue, though, I agree on that, as I have over 3tb myself.
