    Hi everyone...

    I'm in the envious position that I'll be buying a new Mac Pro for work in the next few weeks. I'm hoping the funding will materialize just after the new machines are announced at NAB. I've already selected an HD-SDI card with help from posters here...

    I also need to purchase a large, fast storage solution for storing 10 bit uncompressed 4:2:2 HD from a Varicam - that's 110MB/sec, according to the spec sheet (MB, not Mb)...

    I've looked at the XServe RAID storage and don't like the price. I'm looking for 3-4TB of usable storage that can manage a sustained 120+MB/sec and is resilient.

    What non-Apple options are out there that work well and seamlessly with the Mac?

    You can try getting a hardware RAID controller and a Linux box set up as a Samba server.

    It won't be "seamless", but it will be pretty damned good.

    (Considering an XServe costs like 3 Mac Pros, it is more than pretty damned good)

    There's no way that can keep up with the requirement of 120 MB/s. Even with gigabit ethernet, that's right at the theoretical limit without considering a whole host of bottlenecks that'll slow it down way below that.

    To the OP, are you absolutely sure that's 110 megabytes per second? I don't know enough about high end video stuff, but the little I found from Google (search various combinations of HD, Varicam, mbps, etc) only came up with as much as 100 Mbps (bits). If it's bits and not bytes, then there are a whole bunch more possibilities. Even so, I'd hesitate to go with anything networked, as sustained throughput won't be guaranteed.

    Could you show us a link of what you already have so we can confirm the speed requirements?

    I'll be importing uncompressed HD streams using HD-SDI. The specs for that say "1.485Gbits/sec"

    10 bit uncompressed 720P60 4:2:2 video is 140MBytes/sec.
    10 bit uncompressed 1080P25 4:2:2 video is 132MBytes/sec.

    Note: this is for 60fps, and I'll be doing 24P capture, but the varicam records everything as 60fps and leaves it to the NLE to do the pulldown.

    I would recommend a secure solution (raid 5) the Lacie S2S might suite your needs


    I actually own the S1S but me needs are slightly less

    Thanks, Pengu and Mustard :)

    I'm looking closely at some of the higher end systems you listed.

    I dread to think how long it will take to convert this content for DVD! I'm also hoping for good Blu-ray or HD-DVD burner support by late fall.

    Is anyone out these using an uncompressed HD workflow who might point out some catches and snags I might face?
