    HDD For a server

    We are setting up a fog server and are wondering what HDD would be better a:

    7200rpm, SATA III, 64MB Cache

    or

    7200rpm, SATA II, Enterprise Drive, 64MB Cache

    The Enterprise drive would probably be designed for constant uptime (eg server use) so should be better suited. SATA III won't make any difference with that disk and the load FOG puts on it.

    Do you have any part numbers?

    What is the rest of the hardware for the server going to be as well?

    Enterprise +1

    sata I - 150MB/s
    sata II = 300MB/s
    sata III = 600MB/s

    Serial ATA - Wikipedia, the free encyclopedia
    "As of April 2010 the fastest 10,000 RPM SATA mechanical hard disk drives could transfer data at maximum (not average) rates of up to 157 MB/s"

    Further to my previous message - how many machines would you be imaging at one time?

    This can help gauge disk IO requirements and NIC requirements.

    anything past SATA III on HDDs is a marketing joke. while you can get burst in the ranges of SATA II it's just a marketing ploy to make you think your getting supadupa speeds.

    hard drives cant physically provide a constant data stream anywhere close to SATA III's theroretical limits.

    SSDs on the other hand can or will at least come close, I've never used a SSD nor extensivly reasearched them.
