Select SCSI (Fast Ultra) as the source unit
-
Choose SCSI (LVD Ultra80) as the destination unit
-
Click convert to obtain the equivalent amount in SCSI (LVD Ultra80)
Key Features
-
Converts data transfer rates between SCSI (Fast Ultra) and SCSI (LVD Ultra80)
-
Supports legacy and modern SCSI signalling standards
-
Browser-based and easy to use for quick conversions
-
Helps assess compatibility and throughput in mixed SCSI setups
Examples
-
4 SCSI (Fast Ultra) equals 1 SCSI (LVD Ultra80)
-
8 SCSI (Fast Ultra) equals 2 SCSI (LVD Ultra80)
-
Conversion follows the formula: 1 SCSI (Fast Ultra) = 0.25 × SCSI (LVD Ultra80)
Common Use Cases
-
Connecting high-performance hard-disk arrays and RAID controllers in servers
-
Attaching tape drives and robotic tape libraries for data backups
-
Linking legacy high-bandwidth peripherals such as optical jukeboxes and video capture devices

Full equivalence may not be accurate due to hardware and cable variability
Frequently Asked Questions
-
What does SCSI (Fast Ultra) stand for?
-
SCSI (Fast Ultra) combines the Fast and Ultra extensions of the SCSI standard to enhance device-to-host throughput and reduce latency while maintaining compatibility with the SCSI command set.
-
What is SCSI (LVD Ultra80)?
-
SCSI (LVD Ultra80) is a Low Voltage Differential version of the Ultra2 SCSI interface featuring up to 80 MB/s raw transfer bandwidth on a 16-bit wide bus at 40 MHz synchronous transfers, with improved cable length and noise immunity.
-
Why convert between SCSI (Fast Ultra) and SCSI (LVD Ultra80)?
-
Conversion is useful when integrating legacy Fast Ultra devices with LVD Ultra80 equipment, enabling compatibility checks and performance evaluations between different SCSI signalling standards.
Key Terminology
