I remember the days back, when I first joined the group... oh the hatred for Memorex remains strong!
I went thru Verbatim, Sony.. all the top brands including Memorex, and turned up nothing but coasters.. seemed my experiences were a tad bit different then the rest.
Found out.. even though a lot of people used LiteOn drives, some models were just plain crap. The one I had, made Matshita look like top of the line. Once I spent the money on a recommended drive, I went back to using Memorex myself because, well.. sometimes you just don't have $40.00 a 50 pack, when you can get 50 for $25.
I still have one Verbatim disk in my collection.. and over 500 Memorex. I only have to replace them as they age, or the kids play hockey with them.. as you would any other disk.. including my growing stack of hard and optical drives that have failed over the years. Some things work for me, that don't work for others... can't really explain it.
However, if you want permanent storage on disk, I highly recommend M-Disc. There's a reason they are $86.00 for 30.
