Most definitely! Even the slowest of slow hard drives...
I do most of my burning on a PM7100 with a Yamaha 6X burner. I set
Toast to use a 64 Meg RAM buffer. It doesn't take long for a 5400 RPM
drive to fill the RAM buffer... Almost exactly 1 minute before the
burn is complete, the hard drive stops flickering... Everything after
that is out of the buffer.
Doing the math here... 64 Meg / 6X = 10.666... Meg per minute.
10.666... Meg / 60 = .1777... Meg per second. You'd have to look
awful hard to find a hard drive that slow!
1X refers to audio speed. Digital audio is approximately 41 Khz
(41,000 / second) sample rate. 41 K * 2 (16 bit bytes for audio) = 82
K. 82 K * 2 (stereo) = 164 K... 164 K ~ .1777... Meg - Pretty close
there. (given that a K is not exactly 1,000)
It would seem that the only bottleneck (until ultra-fast,
giga-flop burners hit the market) would be the burner itself, not the
hard drive, SCSI bus, or the computer.
