Comments on: Optical discs to offer 500Gb capacity! http://the-gadgeteer.com/2009/05/04/optical-discs-to-offer-500gb-capacity/ Gadget reviews and news by Julie Strietelmeier and friends since 1997 Fri, 10 Feb 2012 18:50:51 +0000 hourly 1 http://wordpress.org/?v= By: DeepThought http://the-gadgeteer.com/2009/05/04/optical-discs-to-offer-500gb-capacity/comment-page-1/#comment-34594 DeepThought Tue, 05 May 2009 06:13:38 +0000 http://the-gadgeteer.com/?p=15048#comment-34594 Still a mechanical spinning thingy. Surely solid state is the way to go. Then again, if it is really really holographic, we can zap it with a laser and make a copy of all 500Gb in just a blink of an eye. The data rate for such a large capacity has to be of the same order of magnitude to make it meaningful. How long will your USB hard drive be grinding away to transfer all that stuff?

What would it be used for? Back ups? Tera-byte drives are cheap, everywhere and much more read-write friendly than an optical disc. Movies? Doubt it... media groups like cinema have only just started up with 1080HD filming. Picture studios are releasing entire trilogies in 1080 and 5.1 on a single Blu-Ray disc (The Fast and The Furious for example). Unless cinema starts getting recorded at a resolution well over 3000 horizontal lines, a disc of that capacity would be pointless. Recording at such resolution is completely pointless as the difference in picture quality on a 50" Plasma would be negligible. Unless cinema and movies go fully 3D, renders at over 200fps and uses 11.2 audio, there would be no use for the discs there. And as for in the home? A scratch on a CD costs you a split second of audio, a scratch on a DVD can cost between 2 seconds of skipping and disc lock up, a BLU-Ray scratch is similar effect on a higher quality movie. Now imagine the data loss when a scratch penetrates and distorts a hologram of data. I've got 3 kids under 4, all our movies are in DivX on Hard Drives where they can't destroy them after a guest didn't put a disc back in its case and the 1yr old ground it into the floor!

With all these types of external hard drives available for consumer use, where would you find use for optical medial. Aside from maybe putting all your dvds into 1 or 2 discs. I also do not use optical media for back up storage since I have some ext hard drives I use. Honestly the only time I use optical media is making music cds for my car. That way if I forget my ipod or I dont want to hear random streaming music from my bb, I have songs that I like already loaded in my car. I am pretty sure that most companies use hard drive based systems, raids, to back up their system. Nice post but the tech maybe a legacy before it is made for consumer consumption.

I just don't do it. I back up all my data on to external hard drives. I’m probably in the minority here, but I can honestly say that I’ve probably burned less than 25 CDs or DVDs in my lifetime.

I have purchased two 1 GB SATA USB hard drives ($99 each) for the exact purpose. I have stopped using DVD's and have moved all of the data contained on over 300 DVD's to these hard drives. Since this type of hard drive is very reliable my experiment is to remove the need to keep buying more DVD's for storeage of any type of data as well as the need for a optical drive on every computer I own.
