This is a realy cool bit of (new) technology. I used it to do a backup on my computer an it took only one disc for a backup of nearly 100GB! - I've a good compression tool. The great thing is that it can be re-used for a new backup when required. Highly recommended, no problems reading or writing these discs - using the Sony Vaio internal Blu-Ray writer.
TDK BD-RE 2x 50GB Blu-ray Disc J/C (T19450) I bought this for my father, and he says that it works well So for that reason I give it 5 stars, if there was anything to gripe about he would have said, but he didn't, so it's a 5 star review. As many of you are aware you do not get the full amount of space on disks, just like Hard Drives, so just for those of you who do not know this is 45GB in size.
