Pro Tools TDM Mac Requirements For IDE/ATA Hard Drives
32 track, 24 bit, 48 KHz performance from one dedicated internal IDE/ATA
audio drive is supported on qualified G3 and G4 Pro Tools TDM systems*
Drives must meet the following requirements:
Minimum Drive Requirements
● Disk drive rotational speed: 7200 RPM or faster.
● Average seek time of less than 10.0 ms
● Support of the UDMA66 controller
● Drive must be dedicated for audio. Note: Boot drives may be used
for audio tracks, however performance and track count may vary.
● Drives should be initialized with Apple Drive Setup as HFS or HFS+
file systems.
Drive Space Required
● Mono, 16-bit, 44.1 kHz audio requires approximately 5 MB/minute
disk space.
● Mono, 24-bit, 44.1 kHz audio requires approximately 7.5
MB/minute disk space.
Note: Pro Tools has a single audio file size limit of 2048MB, even when
used with Mac OS 9.x and the HFS+ file system. This equates to about 4.5
hours at 24-bit, 44.1 kHz.
*IDE/ATA support is limited to Powermac G3 or later models, which
include a built-in ATA bus. Pre-G3 models that only shipped with SCSI
have not been tested with add-on ATA/IDE controller cards.
