What Is This Tool?
This converter allows users to translate data transfer rates from the synchronous SCSI (Sync) mode to the SCSI (Fast Wide) mode, reflecting differences in bus width and transfer speeds between these legacy SCSI standards.
How to Use This Tool?
-
Enter the data transfer value expressed in SCSI (Sync) units.
-
Select SCSI (Sync) as the input unit and SCSI (Fast Wide) as the output unit.
-
Click convert to see the equivalent value in SCSI (Fast Wide) units.
-
Use the conversion formula or example guidance to verify results.
Key Features
-
Converts data transfer rates from SCSI (Sync) to SCSI (Fast Wide) units.
-
Supports legacy SCSI interface modes used in servers and storage arrays.
-
Browser-based and easy to use with minimal input required.
-
Provides examples for quick understanding of conversion results.
Examples
-
4 SCSI (Sync) equals 1 SCSI (Fast Wide).
-
8 SCSI (Sync) equals 2 SCSI (Fast Wide).
Common Use Cases
-
Evaluating theoretical throughput differences between synchronous and Fast Wide SCSI modes.
-
Upgrading legacy RAID controllers and storage arrays with modern SCSI interface expectations.
-
Configuring or tuning SCSI peripherals in servers, workstations, and archival storage systems.
Tips & Best Practices
-
Verify device negotiation and cable types to understand achievable throughput in practice.
-
Use conversion results as theoretical guidance rather than exact real-world performance.
-
Consider legacy system limitations and newer interface alternatives when planning upgrades.
Limitations
-
Conversion reflects theoretical maximum rates; actual transfer depends on hardware and environment.
-
Legacy SCSI modes may be superseded by more recent interface standards.
-
Real throughput varies with cable implementation, device negotiation, and system conditions.
Frequently Asked Questions
-
What does SCSI (Sync) represent?
-
SCSI (Sync) refers to the synchronous transfer mode of the SCSI protocol where data is transferred in time with a negotiated clock allowing higher throughput than asynchronous transfers.
-
What is SCSI (Fast Wide)?
-
SCSI (Fast Wide) is a SCSI-2 mode combining Fast timing at 10 MHz with a 16-bit wide data bus, offering improved transfer rates compared to original 8-bit SCSI.
-
Why would I convert from SCSI (Sync) to SCSI (Fast Wide)?
-
Conversion helps express data rates in terms of more modern SCSI modes, which is useful for performance evaluation and upgrading legacy storage systems.
Key Terminology
-
SCSI (Sync)
-
A synchronous transfer mode in SCSI protocol where data is sent in sync with a negotiated clock, offering higher throughput and deterministic timing.
-
SCSI (Fast Wide)
-
A SCSI-2 interface combining 10 MHz fast timing with a 16-bit wide data bus to increase transfer rates over original 8-bit SCSI.
-
Conversion Rate
-
The factor expressing how many units of one measurement correspond to units of another; here, 1 SCSI (Sync) equals 0.25 SCSI (Fast Wide).
