  MAC PRO RAID CARD

  Posted by Paul Bundock on August 31, 2007 at 7:57 am

  Hi,
  Will the Mac Pro Raid card(internal) and 2 x sata 750gb drives
  be capable of HD uncompressed 4:4:4 or 4:2:2. Is anyone running a system like this? Would be using Kona3 card as well.

  Go to applestore.

  Select Mac Pro

  Scroll down until you see RAID CARD

  It’s doesn’t give you FCP MB/s ofcourse but lots of information about the RAID/Speed options.

  No 4:4:4 for sure. doubtful for 4:2:2.

  Generally you need at least 5 drives to do uncompressed 4:2:2 HD and 8 drives to do 4:4:4. We have the MaxxDigital 8 drive, 8TB SAS/SATA array and it can top out at 517MB/s. But again, 8 drives.

  I think you’ll only top out around 100MB/s if you’re lucky with two drives.

  Paul,

  Its clear that you’re not coming at this subject from the right perspective. When considering a raid array your considerations cannot be from the standpoint of the minimum requirements necessary to edit a particular format. That would get you perhaps a single stream of your chosen format, and with little overhead for audio tracks and graphics, and even that would begin to lag after it began to fill with media.

  A proper raid configured for professional editing requires not just the necessary throughput, but the necessary “sustained throughput” to edit several streams of your chosen maximum video, plus additional overhead for audio and graphics, and the salient numbers to consider are not the max speed when the array is empty, but rather its throughput when it approaches 85% full (that should be considered maxed out).

  So, two striped SATA drives is not even close to what you need for uncompressed HD, and four striped drives might possibly get you playback of one or two streams without dropping frames, but certainly could not provide the necessary sustained throughput for editing.

  Listen to Walter. An eight drive array is what works for uncompressed HD at 4:2:2 and for 4:4:4 even more.

  SAS/SATA with 7200RPM 1TB drives.
