I've used DVD-ROMs from Toshiba, Sony, and Pioneer. I like them all, but the newer Pioneers are some of fastest performers I've seen and, not that it matters all that much, are the only ones to my knowledge that are ATA66 compliant. I get absolutely no HDD paging at all with either the Pioneer DVD-117 or DVD-120 drives I have. The only drawback in my experience, is that since the drive is always spinning at full throttle, they "seem" have a propensity to overheat and lock. In that regard, the Sony and Toshiba are a bit more reliable.
