I am looking for a hardware port multiplier...I was thinking of the addonics line. There are 3 models I am considering... http://www.shopaddonics.com/itemdesc.asp?ic=AD2SAHPMEU&eq=&Tp= http://www.shopaddonics.com/itemdesc.asp?ic=AD4SR5HPMUS&eq=&Tp= http://www.shopaddonics.com/itemdesc.asp?ic=AD4SR5HPMU-E&eq=&Tp= Has anyone tried these out? Wondering if they are reliable, if RAID-0 is fast, and if RAID-5 is terribly slow.
