I use ImgBurn to rip Blu-ray and DVD ISO files from a set of five identical (and very new) Blu-ray drives on my Win7x64 Ultimate computer, said drives in an eSATA external port-multiplier box, and a port-multiplier compatible eSATA card and drivers. (Asmedia 106x SATA Controller.)
Mostly, it's Blu-rays. Sometimes a DVD sneaks in because it's the only version available, or because it's the cheap extras that come with a box set, as is the case today with the BFI edition of "Dissent & Disruption: Alan Clarke at the BBC (1969-1989)." 13 discs, 11 BD and two of them DVD.
So I'm merrily ripping Blu-rays at 14+ MegaBytes per second each, and I stick in a DVD. Well, gosh if the RIP rate on my DVD is healthy at 8.5 MB/s, but all my BD rips suddenly drop in speed to around 5 MB/s or slower.
I put the DVD rip on pause. All the BD rips jump up to their maximum rate which for a single BD being ripped is around 30 MB/s; with 4 simultaneous rips it drops to 14 MB/s. That's a limitation of speed, network drivers and file server efficiency.
I'm attaching three log files for the DVD and two BDs that were in the drives being ripped when I observed this activity. I put all three ImgBurn rips on pause during the logfile capture, since ImgBurn would otherwise detect the mounting and dismounting and the rips would be damaged or be terminated.
Many moons ago and back in the SlySoft days I was more likely to rip DVD and BD simultaneously, and I never noticed this kind of interaction -- and I was using the same version of ImgBurn. However, my Blu-ray drive stack was a different eSata box back then. Does anyone have any idea whether this issue is possibly related to AnyDVD HD, or my eSATA port multiplier box, or something else?
Any thoughts would be appreciated.
Thanks!
