an optimal connection for an Avid
Media Station|PT client on the ISIS system:
• Average Read: 60–70 MB/seconds
• Average Write: 70–80 MB/seconds
• Peak Read: less than 5 MS/100
• Peak Write: less than 5 MS/100

should not have peaks or spikes that indicate
variable performance within the ISIS system.
