For backup uses, performance isn't the most important thing here. This applies to storage HDs too. You just want the cheapest per capacity, never mind the performance. USB2 external hard disks were my backup for a long time, but now I've got a GBE box things are a little faster.
Having had another look at blu-rays, the biggest ones I've seen appear to be 50GB? I hate to imagine using those... 3TB HDs are a sweet spot in terms of cost per capacity and I'd only need a few of those for the near future. By the time they age I'll be moving them to whatever will be the best cost per capacity at the time, maybe 10TB HDs will be common then or some other storage revolution has happened.
