With all of the archival material on VHS already it will take far more than 10 years for it to disappear entirely. Look at what is happening with vinyl LPs - 20 years on from the invention of the CD there are still LPs in stores. Perhaps not an entirely fair comparison since many feel that vinyl is still a superior format. That could NEVER be said about VHS or Beta vs. a DVD. Still, I don't know anyone who threw out their album collection when they started buying CDs.Originally posted by James_F
But my example is valid. A VHS tape in 10 years will be like betamax was in 1990. Only a few people will have them. Cable/DBS companies like PVRs because they reduce churn. You can't play a tape in 10 years and expect it to look good. While I agree hard drive isn't an archive format, its at least good enought to store the information until you can burn it to a DVD. Look at these new recorders arriving on the market, I think this is how we'll see convenient/inexpensive sharing in 5 years.
Agreed, DVD isn't a great format even for standard definition yet, but as more and more people gain DVD players and recorders such as the panasonic come online, I think we'll see great strides in the DVD-R world, but as you said, right now HDVHS is the only format capable of recording HDTV.Originally posted by Martyva
HDVHS is the only media available to archive HDTV. Unless people get off the blue laser political move, HDVHS may be the only way to archive HDTV for several years. Also there is about 100 million homes in the U.S. with VHS, only about 50 mill with DVD (including computer drives) a couple mill with PVRs, and only VHS is forward compatable to HDVHS
Well, WD has a 200 gig drive out--Western Digital Breaks a Record: WD2000JB with 200 GB--so it won't be too long now.Originally posted by David_Levin
Failures: If you have a movie, you'll probably only watch it a few times a year. That tape is going to last a long time (the hard drive is spinning constantly).
Storage: The new HD video tape can store around 40 gig (someone is welcome to correct me). Go around the house and count the video tapes. That's a lot of hard drives ($$$). When we start talking 1T+ (terrabyte) hard drives then we can talk some more.
People need a convenient (inexpensive) way to share content - that's what Tape or DVD gives you. I think both Tape (or DVD) and Hard Drive storage will survive.
I the real long term (perhaps my dream world), everything will be hooked to some kind of high speed network and we will not need local storage.
Well, let's look at the numbers. I just looked up the original Dishplayer Seagate, a DiamonMax 80 (5400) and a Western Digital 120 gig (7200).Originally posted by James_F
I don't think you'd want a 7200 RPM drive in a PVR, they run way too hot.

The 501 is constantly seeking when powered up, as it is continually writing to the hard drive's buffer. The first unit I owned sounded like it had marbles rolling around inside of it all the time due to the noise the heads made while seeking. The 501 does get pretty hot.The seek power is also pretty ugly though I'm not sure how this effects heat since you're not doing it constantly.
