Negative. They have plenty of space. Every cable company has been steadily reducing the number of analog channels for many years. Each one is enough space for 2 full rate stations (which no one willingly dedicates to a single station -- they're more or less required to for broadcast stations.) TWC has been shown to place 6+ HD stations on one channel. Sometimes that means there isn't enough bandwidth for realtime delivery.
What *is* eating the overwelming majority of space is all the on-demand, iControl(tm) interactive crap they've been heavily pushing for several years. Across the full RF spectrum -- all 134 carriers -- they have room for 400-1000 stations/channels depending on how much bandwidth is allocated; for the 400 number that's just over 12Mbps for every channel which is way more than most channels need.
However, I do, reluctantly, see SDV as a necessary evil. It's the difference between transmitting *everything* and transmitting what's necessary. If noone is watching Lifetime, there's no need to be filling space with it. Look at it like IP multicast; the switch will not put traffic on the wire if nothing on that port has asked for it.
Let the hive mind of Engadget get that for you.
"I'm looking for a solid state drive, around 32 to 64GB, for use in my web server. The drive will contain my web sites and the operating system, either Windows Server 2008 R2 or Ubuntu. Large storage is handled by a separate RAID array, so capacity is not an issue. Rather, I am looking for the fastest, longest-lasting, and most reliable drive under $150 that is suitable to my application. Any thoughts? Thanks!"
