I figured if anyone knew definitively, it would be you :) I will just use the 3124 for now. It has been pretty reliably for me to make these large storage appliances.

Faster is nicer, but cost is a constraining factor. ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
