Hard Drives say Internal (ATA) in Console RRS feed

  • Question

  • They are supposed to be SATA.  Did I miss a necessary driver install at some point?  What's up?

  • Some SATA controllers have several modes they can be configured (in the BIOS) to use. Usually the default is a SATA mode, but there's also usually a Legacy IDE mode, which makes your drives look like IDE devices. It sounds like your board either defaulted to legacy IDE, or shipped from the factory set that way for some reason.

    For installing WHS, Legacy IDE is the preferred mode, if your MB supports it. WHS setup starts with Windows Server 2003 setup, which has limited support for storage devices, and supplying additional storage drivers is annoying.

  • You shouldn't do anything about it. Writes to WHS are very slow (on the order of 2-5 MB/s) when there's more than one drive in the storage pool because of Drive Extender. There's a very small theoretical performance loss from PATA vs SATA, but in reality drives can't keep up with current IDE speeds anyway.

    Now if your read speed is 2 MB/s there's definitely something wrong (theoretical throughput for 802.11g is more like 5 MB/s), but it's unlikely to be PATA vs. SATA.

    So what should I do about it now?  Sorry, this is my first build and I'm a little confused.  WHS is running great right now, but transfers, for whatever reason, are only going through at 2 MB/s.  Does this have to do with the drives being configured as IDE?

    EDIT: Thinking about it, 2MB/s is standard for 802.11g isn't it?
