The stream count values in the table are minimum values for the DDP. The stream count of any format you use can be obtained by dividing 1000MB/bandwidth of your format.

Having an SSD cache and HD Data Locations has advantages:

  • 1. Files transparently can be moved/copied within the HyperDDP12D between cache and spindles without changes to the directory tree.
  • 2. Audio, DPX and low bandwidth video formats which give bad performance (seek time issues) with spindles, can be kept or consolidated on SSDs.
    That way they do not influence the spindle performance of regular video formats.
  • 3. If needed you can split copying / rendering from streaming with streaming materials on SSDs to prevent drop frames.
  • 4. Because bandwidth of SSDs and spindles add up the DDP has a bandwidth of 1 GB/s plus the spindle bandwidth.
  • 5. Files ingested to SSD are duplicated to spindles. The newest files are then on SSD and also on spindles.
  • 6. Folder volume files can be pinned to cache.
  • 7. Folder volume files can be copied on demand to cache.
  • Note: bandwidth during sustained writing or combining R/W may be lower.
