    Perfect for RAID and storage

    Top-notch in my desktop PC, for storage in RAID Mirror!
    Packaging still top-notch, the only point you really need to think about now is finding PC cases compatible with 3.5" HDDs!

    It was perfect.

    Delayed, having been tired, but this order was perfect, the PC has been working perfectly for a few hours.

    NAS

    I needed 2 6TB hard drives for my NAS, on the site there was only one but the salesperson checked whether there was one available nearby.
    That was the case, he reserved it and had it put aside, I was able to pick it up the same day.
    A big thank you to the LDLC employees for their welcome and professionalism.
