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
