Re: DAE outputs? Not all CDRs are Created Equal!

Re: DAE outputs? Not all CDRs are Created Equal!
    So how fast do you want to play your music CD's? Anything over double speed sounds downright weird to me! :D  
    I take the listed speed ratings with a grain of salt or two. My computers always meet the minimum requirements but I can never consistently burn CDR's at the maximum rated write speed so I'll manually select a slower speed to have less errors. In any case I can burn disks at a faster speed on the faster rated drives.  
    It is interesting what you had to say about CPU utilization... were those tests for reading disks or writing disks? At least before the days of on-board buffers you weren't supposed to be multitasking on your computer while burning disks so a high CPU utilization score might not be that much of a problem. But if the CPU is being monopolized during playback that could certainly present problems when playing games that insist on being run from the original disk. :-(  
    For me the only speeds that really matter are burn speeds and digital extraction speeds... assuming that the typical read speed is fast enough not to create glitches while running programs from the disk. I believe that the DAE speed is related to the power of your CPU and I'll typically get 25x from a 48x drive. I've noticed that some drives will include a rating for their maximum DAE speed (which is usually much less than the maximum read speed). As for the referenced benchmarks, perhaps the drive mfg's tweak the test computers to maximum their scores.

P.S. I guess what they say about SCSI is still true. Hmmm... you might want to try some of the ASPI utilities from Adaptec, etc. and retest your drive. I guess that ASPI is the interface between the IDE bus on your computer and the "virtual SCSI" drivers. I've read that your drives won't work properly if the ASPI layer is damaged (but the usual complaint is "my drive isn't recognized in Explorer").
