Too bad. I've found that the driver for the 2410SA (aac) works fine in 64-bit mode;= =20 although I'm not compiling for amd64 right now, but (lack of) problems=20 with the 2410SA isn't the reason. > Then again, I have nothing but really REALLY bad experiences with Adaptec= IDE=20 > RAID solutions, so perhaps you should choose differently there..

The card seems reliable enough once it's up and running, although getting= =20 it configured can be a major headache as the configuration software is=20 terrible and the card itself seems prone to crashing when being configured= =20 (even using the BIOS menus). That, and taking forever to build an array=20 (8 hours for a 400GB RAID-10 seems excessive) and terribly slow write=20 speeds (~7MB/sec for sequential writes to a RAID-10 array - something is=20 seriously wrong with its design for the performance to be _that_ bad.=20 That's the same with different OSes and on different MBs/CPUs as well, so= =20 it's not a FreeBSD or incompatability issue) means I personally wouldn't=20 consider buying another one. The OP is probably better off looking=20 elsewhere. (The hot-swap box is nice, though, although it transpires=20 that's made by SuperMicro, not Adaptec). Chris. --0-962440433-1098169773=:866--
