What is IDE (DMA mode 2)?

IDE (DMA mode 2) is a Parallel ATA data-transfer mode that enables direct memory access with higher throughput and lower CPU load compared to older methods, used in legacy PATA devices.

What does STS3c (signal) represent?

STS3c is a concatenated SONET electrical transport signal combining three STS-1 channels, providing a data rate of 155.52 Mbit/s used in telecom network backbones.

Can this tool physically convert the interfaces between IDE and SONET?

No, the tool converts data transfer rates for comparison purposes only and does not handle physical hardware interface changes.

Tips & Best Practices

Confirm whether your hardware uses legacy PATA or more modern interfaces before conversion
Use this conversion for rate comparison only, not as a physical interface change
Consider network protocol overheads separately as they affect actual throughput
Leverage this tool for benchmarking and troubleshooting legacy storage and telecom equipment

Limitations

IDE (DMA mode 2) applies only to legacy PATA devices, not modern SATA or NVMe hardware
STS3c rates are fixed telecom bandwidths and do not adjust for storage protocol overhead
The conversion reflects rate equivalency but not a direct hardware interface conversion
Actual throughput may differ due to protocol and hardware implementation differences
