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!"
Doesn't DirecTV broadcast in HD-Lite (1440x1080i or 1280x1080i)?
This alone would prevent me from switching.
They do for MPEG2, but considering the number of HD channels available and the amount of bandwidth they will have, there isn't any reason MPEG4 will be HD-Lite.
