RAID Controller Shoot-Out

Posted by ryuzaki0 on from the millions-of-bugs-scream-at-once dept.

mikemuch writes "ExtremeTech has a comparison with benchmarks of three RAID controllers from Adaptec, LSI Logic, and Promise, and along the way gives you a little refresher course on RAID in general and why you want to use it: faster throughput, longer uptime, and improved data security. Motherboard RAID controllers do well when there's 'very little or no load on the CPU, I/O bus, and memory bandwidth. But with heavy traffic and processor loads, the limitations of the shared bus and the benefits of intelligent RAID's integrated IOP and memory cache have a more significant impact.'"

    Exactly. I would think that given the cheap price of hard drives nowerdays, RAID1 would be so very much more adviseable.

  2. eSATA Hardware RAID with port multiplier by gebbeth · · Score: 2, Interesting

    Anyone know of a hardware raid card with a external SATA port that supports the port multiplier feature? I have only been able to find software raid solutions.

  3. Rebuilding? by merdaccia · · Score: 2, Interesting

    There's a stigma associated with host-based controllers that trying to rebuild an array with them is tantamount to masochism. I think it comes from the fact that an intelligent controller can rebuild an array through BIOS-only intervention.

    Anyone care to shed some light on how rebuilding arrays compares when using intelligent vs host-based controllers?

  4. How did they work under? by LWATCDR · · Score: 4, Interesting

    Linux, BSD, or Solaris?
    How about calling it the Windows RAID controller shoot out?
    ExtremeTech should just change it's name to Mainstream tech and get it over with.

    See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
  5. This isn't a shootout by Necroman · · Score: 2, Interesting

    This isn't a shootout, it an advertisement for the cards. They are at different price levels, and ExtreemTech is just showing the difference in performance you get for spending more money. Wow!

    If they tested multiple series of the Adapatec, LSI Logic, and some 3ware cards, I would be more impressed, but this just seems like an all out advertisement to me.
