Overview
StarTech.com’s RAIDBAY3 is the perfect solution for building hot-swap SCSI RAID
arrays. Up to (3) 3.5 inch drives can be installed in this all aluminum chassis, each in
their own independent removable drive drawer. The frame and drawer design of the
5.25 inch full height (2 bay slots) chassis can increase the number of drives that can be
installed inside a case by 33%. Front and rear ball bearing fans ensure plenty of air
movement over the drives to maintain ideal operating temperatures. This ensures long
service life and less downtime.
