What does SCSI (Async) mean in data transfer?

SCSI (Async) refers to the asynchronous transfer mode of the SCSI protocol where data is exchanged through request/acknowledge handshakes instead of a shared clock, with performance depending on device response times.

Is E.P.T.A. 2 (payload) a standardized unit?

No, E.P.T.A. 2 (payload) is specific to the E.P.T.A. 2 protocol and its payload measurement is defined by that protocol's specification, not by a general external standard.

Why convert SCSI (Async) units to E.P.T.A. 2 (payload)?

Converting allows users to translate legacy SCSI throughput values into payload measurements for the E.P.T.A. 2 protocol, aiding performance analysis and planning in systems using this messaging format.
