Tips & Best Practices

Remember the conversion reflects data throughput comparison, not a direct physical unit equivalence.
Be aware IDE (PIO mode 4) rates are theoretical maxima and may not reflect real-world speed.
Note that IDE speeds are usually in megabytes per second while OC1 is in megabits per second, so keep units in mind.

Limitations

Conversion compares throughput rather than identical physical units.
IDE (PIO mode 4) throughput shown is theoretical and excludes overhead.
OC1 rate is in megabits per second; IDE throughput is typically megabytes per second, requiring careful unit interpretation.
