unless you are going to use a new or nearly new drive, chances are very high that the drive itself, NOT the interface, will be what determines the speed of data transfer. older drives can be as low as >5 MB/s sustained internal transfer rate. only the newest drives will have sustained internal transfer rates greater than either of the two controllers you mention. so all the discussion of interface transfer rates is wasted time. a single SCSI drive connected to an Ultra360 controller is NOT going to give you a 360 MB/s data transfer rate. to realize that maximum, you would need to put 10 or 12 LVD drives into a RAID, depending on the speed of the individual drives. and they would need to be relatively new drives to have anything over 30 MB/s internal transfer rates.
HDST or HDTK or some other disk utility can be used to benchmark the sustained read and sustained write speeds of the drives themselves. as i said, unless you use a new drive, this will most likely be lower than the controller, and be the actual limiting factor. choose the faster drive, and use whatever interface it requires. a wise man once observed, "there's nothing more dangerous than a little bit of knowledge." john --~--~---------~--~----~------------~-------~--~----~ You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
