Blu-ray is still in its relative infancy but that won't stop your local IT shop from picking up a few of these hulking UDO compatbile SCSI drives. First, a quick explanation: UDO stands for Ultra Density Optical and it is based on the Blu-Ray standard. However, these disks are encased in a honking big cartridge and use a different aperture of laser.
Why should you care? What we're seeing here is some very early work with Blu-Ray in the wild. While we're not exactly comparing apples to apples here, the reviewer has pitted the UDO drive against a few hard disks and is seeing slightly slower read times.
Overall, this isn't for us mere mortals unless you need to store 30GB on a big ugly disk, but it's a harbinger of things to come.
