Connecting SCSI Drives
SCSI hard drives are the recommended record-
ing media for Pro Tools|HD systems on Win-
dows, and can also be used with Pro Tools on 
the Mac.
Although Pro Tools will let you record to your 
system drive, this is generally not recom-
mended. Performance for recording and play-
back on system drives is sometimes worse than 
on non-system drives, resulting in lower track 
counts and fewer plug-ins. 
For the most current information on hard drive 
requirements and recommendations, see the 
Digidesign website (www.digidesign.com). 
SCSI Requirements
Digidesign recommends qualified SCSI hard 
drives and a qualified SCSI host bus adapter 
(HBA) card or (on Windows systems) a qualified 
built-in SCSI HBA connector on the mother-
board.
For a list of qualified SCSI hard drives and SCSI 
HBA cards, see the Digidesign website 
(www.digidesign.com).
Be aware that recording to your system 
drive can quickly use up available hard 
drive space. This can negatively affect 
system stability and the performance of 
all applications including Pro Tools.
Software RAID is not supported for audio 
drives.
