More Information on Blu Ray Disc

Arrived quick from seller and worked well...compatible with Vegas editing software. I love burning HD files to Blu-Ray disc as it fit way more than DVD's. The end product looks fantastic in true HD quality is way beyond DVD. I also use some Blu-Rays as a media for HD file backups and it does a great job, but may take a bit longer than a USB 3.0 portable hard drive or memory card to write, but if you need space these Blu-Ray disks can be used like a flash drive for backups.

ot one disc in the spindle has become a coaster.
You get what you pay for and I have tried to save money in the past by going with cheaper brands.
From now on I will pay the few extra dollars for good media like this.
Disc writes at drives top speed with no errors. Disc appends with no issues. Surface is surprisingly scratch resistant.

Edit: I want to add something. I have seen alot of negative comments about this media. Just like the media When it comes to the burner itself you get what you pay for. If you have ValueMax CheapO burner 5000 your going to make some coasters due to the poor construction of the burning laser assembly. My friend purchased a $35 clearance burner from a website thinking oh wow great buy. Well that thing has made coasters with anything he sticks in there.

There is no doubt that one or two of these discs throughout a few spindles might be bad but if your getting 10 of 25 you might want to take a look at your burner, or it's firmware, maybe even your pc. Simple things like a flake of dust vibrating on the write head could cause issues.

I have used a fair few of these discs now and I have had no problems whatsoever burning anything to a disc. I burn primarily video files to watch on my PS3 and I haven't had any issue with playback either.

I use Nero 11 for burning the discs and write them at 4x. I have only used one other brand (Sony), which I also had no problem with but was far too expensive per disc.
These are great discs at a reasonable price (FINALLY!).

My only advice; be sure that your burner is compatible. I have seen many people complaining about coasters.. and often its not the product at fault! Be sure you know which media you can use. Also, some burners support on HTL or LTH media so research before you buy!

Otherwise the only downfall I personally have with the disc is that the verbatim label is very vibrant and can be seen through any printed sticker labels I apply.

Update: I have finally gone through this entire spindle of 25 discs and I am happy to report that not a single one was defective! I will be buying another spindle next payday! (3/12/2013)
