SCSI Odometer was written by Optima Technology, a manufacturer of hard disk subsystems. SCSI Odometer may be freely distributed but not sold or modified.
The display keeps a running total of read and write calls and the bytes transferred since the start date. Max, Min, and Avg show the bytes transfered during a given call. SCSI Odometer has two display registers: 'Trip1' and 'Trip2'. Use Trip2 to benchmark a particular session while Trip1 records total drive activity. To clear a trip register, hold down the command key and press Clear.
The ñ number is the percent of performance degradation experienced when mirroring. This is derived from the equation:
ñ = (1-((RW + 1) / (RW + 2))) * 100
where RW is the ratio of reads to writes. For more information about mirroring, contact an authorized Optima Technology dealer.
