What does 1 SCSI (Fast Wide) unit represent in MB/s?

It represents 20 megabytes per second based on the SI decimal definition.

Why might actual throughput differ from the conversion formula?

Because factors like cable quality, signaling methods, and device negotiation affect real performance.

How is megabyte/second (SI def.) different from mebibyte per second?

Megabyte/second (SI def.) uses decimal units (1,000,000 bytes), while mebibyte per second uses binary units (1,048,576 bytes).

Tips & Best Practices

Always confirm you're converting from SCSI (Fast Wide) to the correct MB/s unit
Be aware that actual SCSI throughput may be lower due to hardware factors
Use the decimal SI definition of megabyte per second for consistent measurements
Avoid confusion by differentiating MB/s from binary-based units like MiB/s
