What Is This Tool?
This converter translates data transfer values from IDE (UDMA mode 0), a legacy Parallel ATA interface mode, into STS3 (payload), the effective user-data portion of a SONET OC-3 transport signal. It helps users align and compare transfer rates across different technology generations.
How to Use This Tool?
-
Enter the data transfer value in IDE (UDMA mode 0)
-
Select IDE (UDMA mode 0) as the source unit
-
Choose STS3 (payload) as the target unit
-
Click convert to get the equivalent value in STS3 (payload)
Key Features
-
Converts data transfer rates between IDE (UDMA mode 0) and STS3 (payload)
-
Browser-based and easy to use
-
Includes commonly needed conversions for legacy storage and modern network interfaces
-
Supports network planning, provisioning, and device migration comparisons
Examples
-
1 IDE (UDMA mode 0) equals 0.883354619 STS3 (payload)
-
10 IDE (UDMA mode 0) equals 8.83354619 STS3 (payload)
Common Use Cases
-
Diagnosing throughput and performance of legacy PATA/IDE hard drives
-
Provisioning and capacity planning for telecom SONET OC-3 circuits
-
Comparing legacy storage interface speeds to modern network transport rates
-
Billing and SLA assessment for leased transport services
Tips & Best Practices
-
Remember that conversion represents nominal maximum rates without all protocol overhead
-
Use this tool to assist in system migrations from PATA/IDE to faster interfaces like SATA or optical transport
-
Consider the difference between payload rate and total line rate when planning network capacity
Limitations
-
Conversion values reflect nominal peak rates and exclude extra protocol overhead
-
IDE (UDMA mode 0) is a legacy interface and represents lower speeds than modern networks
-
STS3 (payload) refers only to user data capacity, not the total SONET line rate
Frequently Asked Questions
-
What does IDE (UDMA mode 0) represent?
-
It is the Ultra DMA transfer mode 0 used in Parallel ATA devices, defining nominal maximum raw data transfer rates around 16.7 MB/s.
-
What is the significance of STS3 (payload)?
-
STS3 (payload) indicates the user data portion available for client traffic within a SONET STS-3 (OC-3) frame, excluding framing and overhead bytes.
-
Why convert from IDE (UDMA mode 0) to STS3 (payload)?
-
This conversion helps compare legacy storage device speeds to modern telecom network capacities for planning, migration, and diagnostics.
Key Terminology
-
IDE (UDMA mode 0)
-
An Ultra DMA transfer mode 0 standard for PATA/IDE devices, specifying interface timing and near 16.7 MB/s maximum data rate.
-
STS3 (payload)
-
The portion of a SONET STS-3 (OC-3) frame dedicated to user data after subtracting framing and overhead bytes.
-
SONET
-
Synchronous Optical Network, a standardized digital communication protocol used to transmit multiple data streams over optical fiber.
