This is true. But if you've got time and the money it's worth backing things up on DVD as well... just in case.
Well yes, but they are definately not infallible either.
Just the other week I was putting together a selection of image examples for a client & a couple of the images I wanted were from about 2003/4 when I was still on film & scanned stuff onto DVD.
A few of the DVD's have started to go brownish & take ages to read & display file names & I couldn't get one of the images I wanted off in the end - wouldn't open or copy on my tower, my laptop or Mrs Pie's iMac.
They're all decent brand discs too - Fujifilm TDK etc, & had been stored in a cases & maybe accessed 1 or 2 times during the years.
