MacPro - should I start looking elsewhere ?

[derbothaus]

While I much prefer working under OSX I have to say this; All of my Macs beachball excessively, even my MP. None of the same computers BSOD or slowdown, beachball-like, when running W7, my mini.

Are you running all machines with a similar image? Unfortunate but I am not having any slow downs on my machines. Have not seen the beachball for a while. I run at 10GB memory which isn not very much by today's standards.
How many peripherals do you have attached? Extra external HD's and low memory (slow HD's) are usually the cause of this unless your OS is messed up.

Strange, you could try to contact OWC about this and I bet they could tell you something on this. Is the external drive powered? Not sure if eSATA provides external power or not.

Problem was most likely that it doesn't provide a real eSATA, but rather internal SATA on the eSATA connector -- and internal SATA is certified only for cable lengths < 1m...

Spidey!!!
