@ LIGHTNING UK!~ Well, there's a limited # of ports & controllers; w/that said, I've 1 SSD, 2 HDDs & 3 burners... so let's just call the Intel controller beach front property! I have the OS & ImgBurn program on my C:/SSD & my library of ISOs on my D:(HDD). Which controller should the 3 burners be on, C:\ (with the OS & ImgBurn program) or D:\ (with the ISO file)??? Grazie~ Joey

@ LIGHTNING UK!~ This system is completely new except for the D:\ (Storage) drive, 3 burners & video card; so yes, I reinstalled Windows. No, I didn't enable that option on the previous system. Also, the D:\ drive is 0% fragmented. I think I'll disable that caching/buffering option & try switching the D:\ drive to the same controller as the burners & if that's not better then I'll put it on the same controller as the C:\ drive... & if that still doesn't work, I'll re-enable that option. Ciao~ Joey

@ LIGHTNING UK!~ In light of what you [last] wrote, I wonder if this setting, whereby the OS is caching/buffering, is bad for my SSD because ideally the # of writes should be minimized with SSDs... as it shortens their lifespan. I guess it'd behoove me to conduct further research online, as to an alternative remedy. Again, the D:\ drive is the SAME drive & so it doesn't seem plausible that it would be the culprit, insofar as its "ability to cope with 3 simultaneous transfers. Thanks again~ Joey PS: I'll be sure to make a donation to your outstanding services :-)

@ LIGHTNING UK!~ Well, this time I actually burned 3 discs simultaneously (vs. Test Mode) & 5:20 across the board! That setting was it, so again, is there any potential disadvantage/problem with it not enabled? If not, considering it was very advantageous for my situation, why not have it enabled by default? In any case, THANK YOU VERY MUCH for the great product & YOUR HELP!!! Ciao~ Joey

@ LIGHTNING UK!~ Okay, I changed the "Reading...I/O" option & burned 3 Images/Discs in Write Mode with Test Mode enabled & the time was 5:20 for all 3 drives. I guess that setting made all the difference, eh? WHY would anyone not want that setting enabled; i.e., is there any potential disadvantage/problem with it enabled? If not, why not have it enabled by default??? Now I'll try burning in regular/non Test mode & post the result(s). Ciao~ Joey

@ LIGHTNING UK!~ I ran HD Tune Pro & don't know what to make of the results, so I've included the image. You stated that it seems "the drive can't keep up;" however, all the ISOs are on the SAME drive. Now I'll try the "Reading - Always Use Buffered I/O" option. Ciao~ Joey

@ LIGHTNING UK!~ Okay, I used Discovery Mode & burned 3 DVD-R discs simultaneously in 5:31 seconds, which I think is great!!! My Windows 7 Ultimate OS is on an SSD (C:\), which is where the ImgBurn program is installed & my library of ISOs that I burn are stored on a 2TB HDD (D:\) Now what??? Thanks~ Joey

@ LIGHTNING UK!~ Wow, thanks for the prompt reply & I just updated/edited my post... perhaps lending better insight to my quandary! Trying the Discovery mode suggestion... Cheers~ Joey

Hello~ I just upgraded my computer from 8GB to 16GB RAM, an Intel 2500K i7 to 3770K processor, replaced a mechanical HDD with a SSD for my Operating System which is Windows 7 64-bit Ultimate & finally an ASUS P868 to P8Z77 Motherboard. I'm using the same three SATA ASUS DRW-24B1ST Optical Drives. & running the same version of ImgBurn 2.5.7.0. This new system has far outperformed the old in EVERY way except one... With my OLD system, I was simultaneously burning three 4.5GB ISO/DVD files in an average time of 6-7 min. Now, with my NEW system, it takes an average of 8-10 minutes to burn three discs simulaneously! Maybe a setting or settings need to be changed- even though I didn't have to do anything special when I upgraded my system in the past. My best deductions is that before my OS was on a mechanical HDD & the files were on another HDD. Now my OS is on an SSD & the ISO files are on an HDD. Maybe the 3 burners should be on a different controller on the Motherboard?!? I attatched a copy of the Log & if anyone has any ideas, as to WHY my new/improved system is burning multiple discs slower, I'd MUCH welcome your input!!! *** Notes: a ) If I burn only one single full (4.5GB) disc @ a time, the speed averages only 5.5 min. b ) YES, I am using the same media as before. c ) YES, my Motherboard chipset & controller drivers are updated to the latest versions.
