ProRes RAID for SXR Capture Drives
When SXR Capture Drives are being formatted for ProRes in the ALEXA SXT,
essentially the same happens, but since SXR Capture Drives contain four internal
SSDs, a combination of RAID 1 (mirroring) and RAID 0 (striping) is used, commonly
referred to as RAID 10. Drives zero and one will be combined into one RAID 1 volume
and drives two and three into another. This provides redundancy. The resulting two
RAID 1 volumes are combined into one RAID 0 volume so it can be accessed as one
volume.
Downloading ProRes RAID Data
XR and SXR Capture Drives recorded in ALEXA SXT require Codex Production Suite
4.1 or later for downloading. Codex Production Suite 4.1 or later is included in new
SXR Capture Drive Docks, or available free of charge for owners of older docks.
To download ProRes from XR and SXR Capture Drives recorded in ALEXA SXT, the
ARRI RAID driver must be installed in the downloading Mac. The ARRI RAID driver is
included in Codex Production Suite 4.1, but will not be installed by default. To install,
check the "Capture Drive RAID support" box when installing the Codex Production
Suite.
The ARRI RAID driver has been tested with Mac OS 10.10 und 10.11.
