    Thanks OP, these are CMR drives, which from my understanding are better or more efficient then the SMR/PMR version of these drives. Here is a video that explains the difference.

    Is this a good deal? Considering that it is in fact CMR but 64 MB cache? Good for Synology or QNAP NAS?

    Is there a difference between buying them on Newegg or on the western digital site? They're the same price on both

    It looks that the one at WD website is SMR while the one in Newegg is CMR!

    Looks like the difference is:Ie note the RX vs AX

    And the text on the newegg page:
    This model uses CMR technology and is being renamed "WD Red Plus" to distinguish it from the current "WD Red" product, which uses SMR technology

    First off, Linus looks much better with the facial hair.

    Next... that's extremely disappointing that something like Reds which were always though to be a premium drive for NAS would not make something better.

    I've been using 4TB WD Greens and I don't think the resilver process is anywhere near a day, I'm assuming here that they are not SMR.



    EDIT: So I HAD to test how long a full re-silver would take. Showing 12 hours for a fairly full pool on a 4TB green but the estimate keeps dropping.
