Your IBM Ultrastar drive has an advanced Low Voltage Differential (LVD) interface that supports transfer
rates of up to 160 MB/sec. Your drive will function at the maximum speed supported by your system
components.
To obtain the 160 MB/sec transfer rate, an LVD Ultra 160 controller must be used and single-ended
drives cannot be placed on the same cable with LVD drives. If you have a SCSI controller that does not
support this interface, the data transfer speeds of your system will be lower than 160 MB/sec due to the
lower speed of the controller. Contact your controller manufacturer to determine if your current controller
card will support the LVD Ultra 160 interface.
Note: If you currently have single-ended SCSI drives and a non-LVD controller, LVD drives may be
attached to the existing cable. If you choose to replace your non-LVD controller with an LVD controller,
LVD drives can be attached to the same bus with single-ended drives. However, some LVD controllers
do not support single-ended SCSI drives. Contact your controller manufacturer for more information.
Both these configurations will only allow for data transfer speeds at the single-ended rate.
