- UltraBay: no hot swapping
- UltraBay Thick: thicker version of UltraBay to support CD-ROM drive
- UltraBay II: supports hot swapping, blending has cut out edge on the right
- UltraBay FX: the combined floppy drive and CD-ROM, DVD or CDRW mechanism found in the 390/390E/390X
- UltraSlimBay: supports hot swapping; frame, rectangle like blending
- UltraBay 2000: supports hot swapping; frame, blending has cut-out edge on the right
- UltraBay Plus: same as UltraBay 2000, but can take the UltraBay Plus Device Carrier which in turn can hold the UltraBay Plus c500 Cradle or the UltraBay Plus Numeric Keypad
- UltraBay Slim: supports hot swapping; notably thinner than the UltraBay 2000, cut-out right edge in blending
- UltraBay Enhanced: supports hot swapping; slightly thicker than UltraBay Slim, but accepts UltraBay Slim devices
The pinout switching is done by the BIOS and hardware, so that it is completely transparent to the operating system.
- Floppy drives are supported by the standard floppy driver.
- ZIP drive support is possible through the ide-disk driver.
- IDE hard disks and optical drives are supported by the ide-disk or ata_piix driver in the linux kernel. SCSI emulation via ide-scsi is possible.
- Batteries are automatically handled by the hardware, but can be controlled further by using tp_smapi.
- UltraBay Plus devices should be handled by the USB subsystem, but if the actual devices are is not known.
A CDRW/DVD-ROM Superdrive (scavenged from a Mac iBook) will fit in an Ultrabay 2000. The original face won't fit in the bay, leaving a bare metal front. When the drive spins up, it blows a lot of air out. Maybe that's an anti-dust measure?

- IBM originally used the spelling UltraBay with a capital B and later switched to Ultrabay with a lower b. We are sticking with the capital B here.
