Perhaps you're referring to the earlier USAS which does 3Gbps and is supported by the mpt driver. -- TJ ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

To answer your question, the 29320A-R is a scsi card with HostRaid aka fake raid, no better than any built-in integrated raid found on motherboards. Freebsd only sees the drives rather than the raid array which needs a windows driver. You'd be better served running raid-1 on gmirror or ZFS. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Perhaps anything connected to that drops down to ATA33 (pure speculation on my part) since it was designed for optical drives ...dmesg/atacontrol logs would be useful here. You may want to try dd with the of=/dev/null instead to remove the 2nd variable and benchmark solely the read speed of the 1st hdd. regards, TJ ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Those systems just have an Intel GCLF2 board in them, which has both SATA and ATA: http://www.intel.com/products/desktop/motherboards/D945GCLF2-D945GCLF2D/D945GCLF2-D945GCLF2D-overview.htm Best you mail them to confirm though... They're also fanless. :) Chipset has a fan, however the processor itself is fanless. I've read somewhere that the fan is a weakpoint. Can't personally confirm that since I haven't used it long enough. The GCLF2D is a new revision, slightly cheaper but minus the SVideo-out (iirc), which was found on the earlier GCLF2. SVideo is an unnecessary expense for an appliance anyway. smime.p7s Description: S/MIME Cryptographic Signature

Once you get the higher-end processor, That was my experiense when shopping around yes - annoying as I don't need anything particularly low power (it ain't going to be my leccy bill :-). The Atom 230 and 330 are supposed to be 64-bit capable: http://ark.intel.com/Compare.aspx?ids=36331,35635,35641, but I have not personally tested either with an AMD64 FreeBSD install. I've tried the Atom330 (D945GCLF2). It works fine with amd64...however it's rather wasted for 64bit considering it maxes out at 2gb. But I suppose if you wanted to standardize on amd64 installs, this is good. Gigabit - ok, re0. You'll need 7.2 at least. USB - ok SATA - 2 ports tested only with gmirror, ok.
