well i read most of the posts above… and both sides have good arguments over “which is better” be it DVD or HDD.
the way i see it if money aint a issue and data is super super important to you… get BOTH of em and burn two copies in two different types of media and keep a copy on a external hdd.
me personally though… overall i prefer DVD as for archival use (not every day use) i prefer DVD (quality ones like TY 8x will most likely last 5-10+ years by looking at peoples scans from a few years back that show no degradation etc) cause HDD seems vulnerable to accidental data loss from say a virus or accidental deletion etc etc it just aint “permanent” like DVD is… and since DVD are for archival use that should mean it’s “unlikely” that they will get damaged due to bad handling etc since you wont be using them often… i guess the main thing that seems against HDD, is the HDD’s have moving parts where they could potentially fail at anytime without warning unlike “quality” (TY) DVD’s where if they burn well initially odds are they will last 5-10+ years where as a hard drive “might” last this long but it just seems more likely to fail vs a DVD in my opinion.
but i guess the positive side of HDD’s is… there just easy to use and quick data transfers and like someone said above “a few clicks” and you got access to the data vs dvd’s where u might have to shuffle through a 100+ discs would not be fun etc etc etc lol.
but in my case most of the stuff i backup is XviD movies which i also have a main copy on my hdd for general use and the DVD is in case the hard drives fail… so in my case overall the DVD’s are better than HDD’s for storage… but i can see how for some people HDD’s would be better than DVD’s.
it’s all opinion on whats better and you just got to figure out for yourself what you think is overall better in “YOUR” situation… but like i said in the first sentence if the data is super important to you make atleast 3 backups (1 external hdd and 2 dvd’s (like say TY and Verbatim for example)) and in a case like this it’s highly unlikely all three of those would fail at the same time, hence no chance of data loss
also the argument about “Price per GB” (DVD vs HDD) is getting less and less true nowadays as hard drive prices keep getting cheaper and cheaper. but like someone already said above (as of now) DVD’s are roughly 4-5times cheaper to burn vs using HDD for storage. but as time passes that might get close to the 1:1 price range then DVD wont be so appealing as it is now… and i figure by the time HDD’s get close to the “price per GB” of dvd’s odds are dvd’s will be obsolete and something like HD-DVD or BluRay will be common then etc.
“instead of buying 500gb for 100 bucks
i went with 500 dvd = 2350gb or 2.3TB”
thats a bad comparison… cause for the same “price” ranges you could only get “about” (a little more but this is close) 2 100pack spindles (200 DVD’s total) of quality dvd’s (8x DVD+R TY) which would only be anywhere between 940GB (200 DVD’s) - 1.2-1.3TB (250DVD’s) for same price comparisons… BUT as time passes that 500GB HDD might become 50 dollars. once that happens the argument over price is probably out the window. (since dvd’s are pretty much steady at there current prices and probably will be for sometime to come and hard drives are ALWAYS droping in price)
but even this is still about a 2.x:1 ratio in favor of DVD if your stricktly looking at storage space for your money.
