That's a lot of time spent trashing tape, which I never suggested as a solution. The central question remains whether that single huge disk will provide the I/O rates that you need, and it won't. If video sizes increase and frames/second doesn't, then I/O need goes up so you'll need multiple drives even more. That means the sizes we already have, without fundamental shifts in technology, are even more likely to be sufficient. You'll just need more of them. What part of this math is escaping you?

No math is escaping me. Video is sequential I/O, which hard drives do fine at. Multiple drives is needed under many workloads, but not video. If you want to do video stuff on a laptop you have room for maybe one extra hard drive. And if you are willing to have an external drive (which isn’t too bad), it’s not going to work to plug several hard drives in and expect to RAID them together. Secondarily, there are only so many drives you can stuff in a workstation. A lot of compact ones only have a couple slots in them, and not everyone wants a RAID or JBOD controller with a bunch of ports on it just to do a video workflow. And if you have a video surveillance small server or appliance, you might only have a few slots in it (4 is fairly common). So again, even one or two hard drives is fine for most uses. Not everyone is gonna put a 24 slot JBOD/RAID chassis in to just provide enough storage space for their video surveillance system or whatever.

  > even one or two hard drives is fine for most uses. The scenario you describe hardly sounds like "most uses" to me.
