  • FCP Data Transfer Rates MB or Mb ???

    Posted by Juan Williams on March 7, 2011 at 10:50 pm

    Hi All –

    I am a network and storage guy that has just been tasked with the care and feeding of the company that I work for, I was trying to figure out what kind of data rates we are looking at.

    The specs say Mbps, to me say Mbits, the outgoing admin says the rates are MBytes ?

    Am I looking at 330 MB per sec or 41.25 MB per sec when these systems are running ?

    Thanks for the new guy help

    You can use both Mbps and MB/s.
    Just think that:
    1 MB/s = 8 Mbps

    330 MB/s is the same than 2.640 Mbps. You need something very special to get that speed.
    41.25 MB/s, is 330 Mbps. That’s a normal speed for a FW800 HD.

    You can have a look to the Activity Monitor > Disk Activity, to see the read/write speed of your HDs when working.
    Down in “Data write/read speed”, you get it in “MB/s”.

    Thank you for that ! I have yet to see the systems in person but knowing that this is for DVD production, 330MB per second sounded unrealistic, but the previous admin was sure that was the transfer rate.

    Since my post I have received a hardware list and drive sizes etc and with info gained here it is 330Mb per second / 41.25 MBps. The hardware and network would never support something that huge.

    Thanks so much !

    Big B = MegaBytes, small B=MegaBits.

    To get from Bytes to bits, multiply by 8
    To get from bits to bytes, divide by 8

    Marketing people tend to express elements in Megabits, because the numbers are largers.

    Best,

    Hey thanks you guys for the 1:8 byte/bit ratio…. very helpful in getting down to real world practicalities
