Partition Size, What's largest recomend for AVID Xpres P Options

[BigWilson]

I have a 1.6 TB LaCie that runs internal RAID and is faster than my 500Gig Lacie (72 Mb/sec vs. 52 Md/sec) and have it partitioned as 3 500 gig sectors. I get the beach ball when saving a digitize, where I don't on the 500 Gig drives even though they are slower. All are connected to 800 Firewire and all drives are 7200 RPM. I think it must be something else because my bare 500Gig Lacie is the same size as each partition and I don't have the problem of waiting with the 500's.
Thanks

Does it change something if you reverse the order ? If so, it's the bus, if not, it's the LaCie drive

If it's the bus, the easy solution (providing there's no hidden problem) is to use a dedicated Firewire PCI card. It's not that expensive, and it'll work better than Apple FW800 anyway. I remember vaguely of a problem when multiple FW800 HD are chained, it slows down, I have myself 3 Drives on one port, but if it is slowed down it's not noticeable in my use/config (icecube/pleiades enclosures).
