ripping BD with BD ROM drive in external enclosure via USB 3.0

[briansmccabe]

Hi all -

I'm a bit puzzled. I had a 2x BD-ROM drive that I had in an enclosure that claims to support USB 3.0. The length of time it would take to rip a BD was generally in the neighborhood of an hour.

The drive was starting to show signs of being problematic, so I bought a new one. My new drive is 12x.

With my previous drive, I had always attributed the relative slowness of the rip to the drive speed (to my knowledge, 2x BD read speed tops out around 9 MB/sec, though I very often achieved speeds that surpassed this).

Based on my arithmetic, my new drive should be capable of ripping up to ~ 54MB/sec. This is according to the speed chart on BD's wikipedia page. However, my new drive doesn't rip at a greater speed than my old one.

The USB 3.0 interface should definitely not be the bottleneck. I know USB is shared bandwidth, but I have nothing else attached to the computer via USB except my wireless mouse.

Anyone have any suggestion? I was stoked to get a big jump in speed but it doesn't appear that that's going to happen.

Thanks

Riplock?

And I assume you know about how the speed peaks somewhere around the middle of the disc.

I have noticed that speeds tend to peak around the middle of the disk. It still doesn't come anywhere near what the top speed is purported to be. And I confess, I have no idea what you mean by "Riplock."

OK, I just read the wikipedia entry on riplock. Interesting stuff. Thanks very much for pointing me in that direction. I'm curious if you know of a repository or knowledgebase on drives affected by this. Thanks again!

I would just google for your model number + Riplock.

Thanks man. I did that, learned a bit about MCSE, and am now ripping at substantially faster speed. Thank you SO much for your help man!
