I am planning on adding 2-3 additional internal HD's to my Powermac G5 using the SwiftData 200 (available at Transintl.com). Can anyone give me input as to which of the following two setups is best? I plan on using the RAID for DV editing. 1. Two Maxtor 300GB HD's (7200 RPM, 16MB buffer, model 6B300S0) --OR-- 2. Three Maxtor 250GB HD's (7200 RPM, 16MB buffer, model 6B250S0) All things being equal (e.g., SATA RAID card, cables, etc.), which of the two configurations would provide the best and/or most reliable performance? Also, should I be concerned with the additional heat generated by 3 250GB HD's versus two 300GB HD's? Finally, since HD's get slower as you start to use the inner tracks, would I experience a slow-down quicker with the 250GB HD's versus the 300GB HD's?
