I have had several of the 3 ware ide raid controlles in my machines over the past few years but never have used one of the sata raid controllers. I'm thinking that I'm having a speed problem with ide 3ware raid an want to try out the sata version. I have seen that several people have had problems with sata an want to make sure that if I install one an use it as the boot device that I want run into any problems. I plan to use the Escalade 9500S-8 Storage controller (RAID). Thanks for any info on this one. If this is not a good controller an can you recommend one that your using with good drifve speed. Our server here is has asus k8v 64 bit mother board with 3200 amd cpu in it. I have about 26 or so computers logging onto this server. Since our accounting software upgrade (accpac) we have been seeing some slow downs in accessing it over the network, an from what I can see it not a network/bandwidth issue nor a ram problem so im thinking it might be the ide harddrives an filesystem. also seem to have a slow backup backing up to dlt vs80 tape drive. Before the upgrade we were not experiencing this slowness in using accpac on same machine.
