Thanks for input. Optical RAID is feasible. Apple seems to have a bit more flexablity with devices; the link above is a guy who set up five USB floppy drives in a stripped array, RAID 0, with OS-X. Not sure a traditional optical image would work, but with a â€œdrag to discâ€ program that seeâ€™s optical like a hardrive, I think that would work with traditional RAID controllers-if you can get them shake hands with the optical the way OS-X does above.
Access times? Iâ€™ve seen Blu-ray access times about double that of regular DVD, and the best Blu-ray access times Iâ€™ve seen are still well over 200ms or about 220ms I believe. Regular DVD is around 160ms. For transferring large chuncks of data, as in backup, I donâ€™t think access times are that critical. Iâ€™m not sure RAID 0 has that much effect on access times. Access times are critical for real time software like gaming software, but why run that off the optical when you run it off the hardrive with a virtual drive? I used to hate the optical drive tilâ€™ I started using a virtual drive for those applications. Now if I can copy the disc to hardrive, I do. One optical drive is fine for copying my discs to disk. I like the idea of having a 50 GB virtual disc with 100 MB/s transfer speeds.. The regular DVD drives donâ€™t cost much these days, so itâ€™s a fun idea to play with. And maybe if enough people started playing with that idea, the Optical â€˜associationsâ€™ would start spinning the new DVD formats a little faster, a little sooner, instead of dealing our performance like a coke addict on his last gram of product. Blu-ray discs spin about 15 times slower than regular DVD and transfer DATA half as fast(9 MB/s for 2x Blu-ray compared to about 18 MB/s(average) for the faster regular DVD drives). Right now, they can take thier sweet time and youâ€™ll get what they decide to give. Youâ€™d hope the DOJ would check into that, but donâ€™t hold your breath-theyâ€™ll get a cut of the consumer pie down the road.
Thanks again for your reply.
