Roberto, sorry, I only saw the further replies after writing mine. Yes, it's a completely different chip. I think I used it the first time about two years ago. I was given a backup server (as in space to put backups on via samba) to set up - old P4 with a bunch of SATA discs and an LSI card. Performance sucked badly, I thought it was the megaraid driver. Ended up loading Win2k3 server with the newest drivers, and I still got only about 6mb/s sustained. Finally chucked out the LSI and got one of these Adaptec cards - immediately the performance jumped to about 50-60mb/s sustained - which I think is about as fast as that P4 can drive a gigabit NIC. I've used the Adaptec cards ever since and they've served me well.... Hans -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
