Does anyone know why I might be seeing such slow write speeds when creating Blu_Ray ISO files either from a previously copied Blu-Ray to file system source or directly from the Blu-Ray disc source ? The best speed I can get is 2.7X, which takes 2-3 hours per Blu-Ray to create the ISO. On regular DVDs I get speeds in excess of 174X and it will write out a 5GB DVD ISO in two minutes. I've checked all option and can't find anything. I've tested 9.1.3.6 and 9.1.3.8.

Post your internal log for the long attempt. I can't reproduce it I just did a BD from the disk folder in 6 minutes and wrote it to another HDD in 2 minutes with 9.1.3.8.

Same here as 90312, no speed issues using v9138 from a folder on an eSATA drive to an internal drive, a 17 GB main movie to ISO in under 3 minutes, about 100 MB/s, 74x.

Ok, I did more testing and the issue is related to writing to a network drive vs. local drive. Local drive is fine. Using a network drive for Blu-Ray I get 2.7X, even though I have a gigabit based network. On DVDs I don't see this and I get great performance around 28X and over 300Mb/s. Just writing Blu-Ray ISOs are slow on the network drive.

Tonight I tested 8.2.3.0 creating a Blu-Ray ISO to my network drive and it was fine. < 30 minutes to read the Blu-Ray and write the ISO across my gig network. Looks like something changed in v9 somewhere.

I tested v9.1.4.0 and get the same results. I honestly wasn't expecting it to be different since there was no mention in the release notes but I figured I'd test just the same and see.

Was this ever resolved as to why it's happening. I have the same issue, so I've been writing the ISO and converting to MKV. Then writing the file to my NAS via Windows Explorer.

Internal (local drive) ISO creation works ok, but when the ISO is created through LAN to a drive located in another PC, the creation is extremely slow (tooks approx. 4 hours). Software version 9.1.7.9. I never had similar problems with versions 8.x.x.x or earlier, seems that there is something (wrong) with this new 9.x.x.x version. Has anyone / DVDFab team found a solutions for this problem?

I just posted about this in the "general Forum". I also am experiencing very slow (1.7) iso creation speeds writing the file across a network. Once the current movie is done, I will try creating the ISO image to a local drive instead to see if that fixes the issue. My network is gigabit speed compatible (switch and router) with sinology DS413j NAS. Thoughts?

Update: After reading another thread it seems as if fab v9 might be to blame so I downloaded the last version of 8xxx QT, setup everything identical to my current setup in version 9 and sure enough..... I'm now getting speeds of around 6.5x while the ISO is bring created. So what gives?? Suggestions?

I just did one that I saved to a local disk instead of my NAS, and it increased speed by a factor of 10. Why, I don't know but the faster speed is still within the realm of the gig network and normal speed between the comupter and NAS. Kevin

Is there any update on this issue please?

Can we please have an update on this?

Kind regards,

There is nothing to update AFAIK. To my knowledge there have been no changes to the way DVDFab handles hard drive I/O since long before v8, so I can't account for any difference in speed there unless it is related to the burn engine. You can try changing that to see if it makes any difference (it will not in Clone mode).
