Due to this, the disks at work are frequently antiquated and slow. In order to prove my point, I built a NAS using OpenFiler, and it absolutely *smoked* the performance of our multimillion dollar Storage Area Network. The guys at work weren't too happy about that. Anyways, you can get wicked performance out of "free" solutions like OpenFiler. Sun's ZFS is neat too. Have fun. |

The Fujitsu Eagle was the hot drive around the time of my first hardware design job involving mass storage. The controller was the Zylogics 440 2 Multibus board set with a microcoded bit slice, and then the 450 where they got it down to one board.
Now that's a disk drive, $10,000, 600W, 470 MB, 130 lbs: http://museum.ipsj.or.jp/en/computer...disk/0013.html Takes 30 seconds to spin up. IIRC, the blower on it (for cooling) was so loud that you had to raise you voice to talk over it, if you were anywhere close to it, LOL! Last edited by PB2; 1st October 2009 at 03:02 AM. |

http://www.newegg.com/Product/Produc...82E16822332010 Is this what you're talking about? Or something much more high end being that you mention multimillion dollar systems. I find that in most businesses hardware is kept for a very long time because it is so much more expensive and any change might cause down time. Only companies that require the latest and fastest to succeed upgrade often IME. Pete B. Last edited by PB2; 1st October 2009 at 01:10 PM. |

A PC running FreeBSD is like the Motorcycle. See what happens if you try and serve 2,500 desktop machines with your "fast" server. For home use, of course you want the motorcycle. The other way to measure is "performance per dollar" or performance per watt of power. The PC based "fast" server may loose if measured that way The best why to grade a system is if it is well suited to its purpose and no more costly to it needs to be for that purpose. (agree about ZFS. I'm a long time Solaris fan and user going back to the eary SunOS days when it was MC68000 based.) |

Not sure if FreeNAS will take advantage of the system ACPI sleep modes. Seems the options in the menus are for the drive, but they do seem to refer to the system also.
Just uploaded a 12.6 GB directory, and saw 85 to 95 MBps reported in the monitor, and about 50% CPU utilization. |

I have a nice clean 800 MHz P3 tower here that would also work well. It idles at about 74 W, 73 W with the disk spun down. Can't get it to go into standby mode.
The Dell P4 tower draws about 6 W in standby. |

Doesn't seem that FreeNAS will take advantage of S1 or S3 power saving modes. It would be a nice feature for them to add:
