Featuring the original NAS hard drive colour, the WD Red Pro 12TB continues the success of WD Red products by adding support for 1-bay to 24-bay storage systems for medium and large businesses. WD Red Pro hard drives include exclusive WD NASware 3.0 technology that provides unmatched compatibility, reliability and performance.

    Flawless for my storage

    Hello the LDLC Wittenheim team,

    It has now been a few weeks since the three Western Digital Red Pro 6 TB hard drives joined their new home, and I have to say I am completely satisfied with them!

    They quickly found their place and run like clockwork. The performance of these models (7200 RPM and 256 MB of cache) is clearly noticeable: transfers are fast, stable, and responsiveness is there. This is exactly what I needed to secure and centralize my data with complete confidence.

    A big thank you to the Wittenheim store team for the order and the quick availability. It is flawless, I recommend it without hesitation!

    High-performing but noisy

    Performance in line with my expectations, I've never been disappointed by WD!
    Purchased to replace an ageing "classic" Red, this Pro version is still noisier, which can be annoying depending on the room where it is installed.
    LDLC delivery is always top notch, ultra-fast and very well protected and packaged!

    Good record

    The hard drive is very good. I haven't yet been able to measure its performance. As for reliability, in the past I've had specialist RAID drives that lasted at least 5 years, and if I've changed a few, it's because I was running out of space, not because they'd failed. The drive is still a bit noisy when it's performing operations (it 'scratches'), hence one less star.

    As good as ever

    The main point has been made in these comments.
    I just want to clarify, approximately:
    150 MB/s writing
    250 MB/s reading

    Of course, as always, less efficient with small files.

    True to form, as always!

    The WD Red Pro 14Tb joined its little friends in the NAS without a hitch. Nickel installation, immediately recognised, it does its job perfectly as expected. Quiet, reliable, perfect for long-term storage. A sure bet for demanding NAS users!
