Your mileage will vary greatly depending on your system. I expect my speeds to improve when I update my computer. I encrypt my disc's which take forever (about an hour) since it's 25 GB at a time! The physical burning currently takes about 8-10 minutes and the verification process takes another 15-20 minutes. The actual hardware burning is the fastest part of the burn process for me. It does get quite loud when it spools up to full speed but no louder than any other optical drive I've used. It been flawless with reading and writing. I expect the speed to be faster when I upgrade my computer to USB 3. I've read about 20 DVD backup discs without error and I can copy all 4.7 GB onto my computer in about 6 minutes. So far I've burned about 6 disc's with zero verified disc failures.

I use the Verbatim 97457 25 GB 6x Blu-ray Single Layer Recordable Discs. (See user photos above.) My computer is a 3 year old MacBook Pro running Mountain Lion and I use Toast 11 with the Blu Ray add-on for my burning software.

I put this drive in a Vantec USA NexStar DX External USB 3.0 Enclosure which I highly recommend. I bought this drive to consolidate my DVD backups and reduce my disc collection by a whopping 80%! I found the drive for a better price on a site with an egg in the name.
