    Default Why reviews not mention PWDIS feature?

    Modern enterprise hdds use pwdis feature so 3.3V pins needs to be removed when using at home(ex. HDD shucking)... I wonder why reviews not mention about pwdis support, it would be really helpful.

    Because nobody is using enterprise drives in their DIY PC. And enterprise servers shouldn't be using ATX power supplies.

    No. He's talking about enterprise drives with PWDIS.

    It's a stupid design.

    Well, at least nothing dies with a normal S-ATA Connector.
    Though the Drive doesn't spin as one of the 3 3,3V Pins on the connector is misused for something else...

    ...Does the normal HDDs without PWDIS work without 3.3V?

    Are there even HDDs that need 3,3V??

    I heard that there might eventually be some discs that might need it, never seen that label though...

    I have seen a couple of Seasonic PSU reviews mentioning this. Seems that Seasonic PSU SATA power cables have 3.3v lines, but at least some Seasonic PSUs come with adapters that pass through all the SATA lines except the 3.3v ones, leaving one with 3.3v-free SATA power connectors.

    Pair of wire cutters does the same thing.

    The point was that somebody did mention the 3.3v-free SATA in a review.
