Can anybody tell me what exactly the hard drive cache affects? I'm probably going to buy an OWC elite, and am trying to decide if I should get a 8 or 2 MB cache drive. I'm using a digi002 on a 667MHz Powerbook and Digital Performer 3. I keep getting an error when I move the latency up to an acceptable level, and I'm unsure if it's because of my internal hard drive on my laptop, or if it's something else...slightly more sinister. I'm hoping that recording to an external drive will destroy these errors. BTW, it gives me these errors when I have tracks record enabled, but no actually recording. Is this the hard drive cache, or disk speed, or does it have nothing to do with that. Does anybody have any insight please?!? Thanks!!
