Hi,

I'm looking at a new drive to put in my Mac Pro Dual 2,66.
It's purpose will be to use it real time audio and to store
projects.
Here's what I found :
Seagate 750 GB SATA II 7200 RPM 16 mb 
Specifications 750 GB 
Model Number ST3750640AS 
Interface SATA 3.0Gb/s 
Cache 16 MBytes 
Capacity 750 GB 
Guaranteed Sectors 1,465,149,168 
PERFORMANCE 
Spindle Speed 7,200 rpm 
Average latency 4.16 msec 
Random read seek time <8.5 msec 
Random write seek time <10.0 msec 

Is this drive ok for real-time use and back-up ? 
Buffer size 16 mb OK ? 300 mb transfer data ok ? 
Is this a good ( best ) choice for Mac Pro 2 x 2,66 GHz ? 
Any thoughts and comments welcome !

I for one would not use anything larger than 250 GB for real time  
audio. Guess I'd rather put a 750 GB one for system or backups, and  
250 GB ones for real time work... Just my $0.02.

Best,

Andy

...And here's why:
