Well, my experience is that the higher speed (SATA II) succumbs to signal noise easier and therefore some enclosures even with good cables and controllers cant do SATA II. This is what I suspect about the HP models, similarly to you. I may go with an MSA50, its cheap and I might just do SAS drives.

I don't think an SAS controller exists that doesn't support SATA II - I've used Adaptec and LSI Logic, which are the 2 big names here. I think it's more a case of what HP "supports" - they'll guarantee SATA I, if SATA II works great, but if it doesn't work don't complain about it. CAVEAT: I've tried putting SATA drives in SAS enclosure - the ones with an expander chip. With normal consumer drives the SAS controller would throw topology errors. I ended up using Western Digial RE and RE2 SATA drives (RAID Edition) - even though they're pure SATA, they have an SAS WWN. Joseph L.
