Just how high is that definition?

Only three hours of high-def video on a 160 GB hard drive seems awfully low to me. When I record high-def broadcasts on my hard drive, they are usually around 8 to 9 GB per hour. I would think that this drive could hold around 16 hours of high-definition video, and that is with Windows and a high-definition video player installed.

I agree

Yeah pretty 160GB is way more then 3 hours of high-def video. Because it's would come out something like 50GB+ for an hour of video?

That can not be true because the next generation dvd disks handle only 30GB/50GB depending which format they go with. How would they expect to put 2 hour movies on disks?

uncompressed

not sure what this reporter is going on, but i'm assuming he's talking about uncompressed HD. Next gen dvds use compression technologies and so do your HD broadcasts. Uncompressed HD would indeed take up a crapload of space... but you wouldn't use a laptop for that anyway.

i was thinking the same..

3 hours??

why would anyone use uncompressed high def instead of mpeg 2 or h.264?

bitrates vs 160GB

at 19mbps (maximum hdtv broadcast quality) that is ~19 hours of HD video
Here's a site that displays bitrates for hdtv broadcasts

http://www.widemovies.com/dfwbitrate.html

hdv format is 25mbps so the drive would be good for ~14.5 hours of that.

I don't expect many laptop users are going to have any video at a higher bitrate.

Two links to SEAGATE.

Make sure you refer to: 5400.3

This is S-ATA so 150 mb/sec, which is hdtv 1080p range, however rest of mainboard slows that down to less than 12 mb/sec of final output or EDtv.
