32-64 track performance with Pro Tools|24 requires the following
configuration:

recommended
● More than 32 tracks requires a Pro Tools|24 Expansion Kit (which
is supported but no longer available)
— OR —
● Upgrading to a Pro Tools|24 MIX System by adding a MIX Farm
card. If adding MIX Farm card(s) to Pro Tools|24 system, refer to
the Pro Tools|24 MIX System compatibility information.
When using QuickTime movies with Pro Tools|24, for reliable performance
of 16 or more audio tracks, audio drives should be connected to a
compatible SCSI HBA card, with video drives connected to the Macintosh
internal (preferred) or external bus.
With 9600 and 9500 Power Macintoshes the following
configurations also yield up to 32 track performance. (G3 computers
do not include a Fast SCSI bus or separate internal and external SCSI
busses)
● Use of a combination of Pro Tools-qualified hard drives connected
to the CPU's internal and external SCSI busses. Digidesign
recommends that internally mounted drives are installed according
to the drive manufacturer's guidelines.
● Use of two or more qualified hard drives connected to the CPU's
internal Fast SCSI Bus.
