October 16, 201015 yr Hi! I bought the Supermicro C2SEE and try to figure out what choice might by the best for a CPU. The box should have: - enough power to operate the 20 drives unRAID offers - enough power to operate at full gigabit lan speed - enough power to rebuilt a disc (in case of failure) within a few hours. Don't want to wait a week. The power consumption is not that important because the system will not run 24/7. But of course...less is better. The "20 drive beast" in the Wiki uses a Intel Celeron 430. http://lime-technology.com/wiki/index.php?title=Hardware_Compatibility#Recommended_Builds I considered an Intel Dual Core (boxed) E5400 (2x2,7 Ghz): http://www.planet4one.de/planet/wbc.php?sid=2044728d8e7c4&tpl=pdetail.html&pid=335786 Might be over the top...but I don't want to buy a new CPU next year when I figure out that it is not enough to power the RAID. Bye.

Bye. Any CPU will work. Even the Celeron 430. Nothing will provide what you are asking. The CPU is typically sitting idle, even when re-constructing a disk it will only be a few percent busy. Nothing will allow the server to be limited by the LAN speed when writing to the array. The bottleneck is the rotational speed of the hard disks. Nothing will rebuild a disk in a few hours. (well, not unless it is a 500 Gig or smaller disk) Write speed, at best, averages about 85MB/s for ANY disk on the outer tracks. That could go as low as 60 MB/s on inner tracks on the disk. It is a limitation of the hard-disk, not the CPU. You do the math. Joe L.
October 16, 201015 yr Any CPU will work. Even the Celeron 430. I see people talking about "any cpu will work". . . "Unless you're running lots of software". And I take that to mean specific unraid scripts / programs. It has me wondering what highly desirable scripts would one want to use, that might make someone regret buying a super low power processor?
October 16, 201015 yr Things like a streaming media server, or ripping software are the main culprits I think.

If you are running VMWare virtual servers, or transcoding videos using ffmpeg/AirVideo or something similar, then then extra CPU power is needed. For any normal file-serving it is not.
October 16, 201015 yr Author Hi! Thanks. I bought a 2 Ghz Celeron. The power consumption is listed with 35W for the 2/1,8 Ghz Celeron. Bye.
