It is more SAS then SATA card. As far as I can say, SAS controler are SATA compliant. In this particular case, the description from Adaptec reads "Cost- effective I/O supporting SATA and SAS". That's fine, if I can upgrade to SAS HDs later, it's a cool feature. >> Any PCIe card suggestion is appreciated. > > FreeBSD 6.x is already legacy.

And more importantly, I own a second server, hosted in a datacenter: I try to keep OS version synchronised, so that I can test buildkernel/buildworld/install on my local computer before trying the update on the (very) distant server. > What I have tested: > - SiI3124-based - fast and functional.

In fact, everything comes from the fact my system behaves strangely from time to time. Long explanation here: http://lists.freebsd.org/pipermail/freebsd-hardware/2007-June/004541.html This problem disappeared for a long time, but came back just today. My wifi card is PCI, and according to the motherboard setup, PCI bus is on the same controller as on board SATA (with PCI-X too). The only slots that sit on a different chip are the two PCIe. I think that if I could move my HDs on the PCIe buses, it might resolve my problem. Even if it does solve this issue, it'll give me SATA II, in replacement of SATA I motherboard connectors. Either way, I win :) pat --Apple-Mail-3-669658806--
