   YYMV, and longevity likely differs from initial reliability, but   
   after I had used Verbatim brand DVD+/-Rs and BD-Rs for some   
   years, I got annoyed by somewhere around 10%-20% of my burn   
   attempts becoming coasters--and buying a new drive because I   
   suspected the laser was going blind.  I bought three packs of   
   Verbatim, PlexDisc, and MicroBoards 25G BD-Rs and kept track of   
   how many coasters vs. good burns I got from each brand.  Verbatim   
   had a high coaster rate.  The other brands had nearly zero   
   coasters.  I am basing my future purchase decisions on those test   
   results.
