Sony BD-RDL Recordable Dual Layer Disc - 50gb, 2X Review

Average Reviews:

(More customer reviews)I like the promise of Blue Ray, but as an old computer tech who's fought a lot of bleeding edge tech battles over the years, I have to warn you that the reliability just isn't there yet for the write-once disks. Although I haven't had any problems, I've heard of a number of ones relating to the write-once disks, which then become expensive "coasters." Instead, for now at least, choose the rewritable disks, which, although more expensive, you'll avoid costly failed disks until the write-once ones are more reliable.
I don't know what the technical reason for this is; however, Blu Ray uses a different dye technology from standard DVDs. Instead of the super-cyanine dye used by companies like Taiyo Yuden, the phthalocyanine dye used by Mitsu Advanced Media and Mitsubishi-Kodak's media, and the metal azo stabilized dye used by Verbatim, Blu Ray uses a phase change technology, in addition to the shorter wavelength laser. In some ways it's not so different from the rewritable DVD technology, or DVD-RW, which uses the phase change in an exotic alloy, Ag-In-Sb-Te alloy, except for the fact of course that the dye is an organic optical dye rather than a metal alloy.
These problems remind me of similar problems I had with ordinary CDs back in the days of early CD writer and DVD writer software. Back then, I wasted many CD and DVD disks until the software became less buggy. Still, I like the Blue Ray disks since they are cheaper for the same amount of storage than a comparable size mini cruzer, which in fact aren't even available at this size. The 15 gig mini cruzer that I bought was 100 bucks. The Blue Ray disk give you two to four times the capacity for significantly less. Unfortunately, compared to a mini cruzer RAM module, they are slow. Copying a 4 gig mini cruzer is around 5 minutes on my system. A 25 gig Blue Ray is over an hour, so be prepared for some long burn times. But overall, a big improvement in capacity over the previous standard.
