Now that's solid

Very good hard drive, perfectly finished and very responsive. Intuitive installation. Highly recommended.

never started...

This isn't necessarily due to the quality of the product (transportation?!). But anyway, when in doubt ;-) I'm still giving them zero points (they should have packaged it better). At least this gives me a chance to vent (we waste so much time dealing with this kind of crap). I hope LDLC will come through. To be continued...

        Impeccable

        I was able to change my order and I was reimbursed... very clean and very commercial...
        Perfect.

        Correct

        Good finish, it made a few scratching noises at the beginning when copying certain files, which was a cause for concern, but since then it has remained very quiet, I've copied quite a few large files and it works perfectly.

        Very good tool

        Let's start by pointing out that the printed manual clearly indicates a HDD with USBc 3.2 (and not 3.1 as in your product description).

        No particular problem, apart from the (preferable...) need to switch it off manually each time the PC is switched off.

        And when you switch off this External HDD, you have to wait for the On/Off button to light up in blue, then press it for at least the 4 seconds indicated in the manual...

        It's a bit 'archaic'...
        As for the On/Off button, it bursts so brightly with blue light every 7 to 8 seconds when the PC is running and it's hard "On"... that I had to glue on a furniture felt pad to hide 90% of its glow.

        Top

        For Time Machine backups on the Mac, it's great. With 20TB, you've got plenty of time. What's more, it produces very little spinning noise, even if it still 'scratches', and it's not very big compared to the LaCie d2 generations I knew 10 years ago.
        Quality post office delivery.

        Perfect

        I have been buying from LDLC for a long time and I am very happy with the professionalism of this company.
        Whether it's for orders or for advice, which is always fast and efficient.
        As for the equipment ordered, I know it well and I am not disappointed.

        not bad

        Very good hardware but a bit slow, a lot of inertia before accessing. On the other hand, once it's up and running, it's very fast at writing.

        Very good, reliable, quiet and compact product

        I have nothing to say about this product, which is of very good quality, in line with the good reputation of this brand.
        I highly recommend this reliable, quiet and high capacity hard drive.

        Good backup storage

        We'll have to see in a few years, but it's rather reassuring to finally have a backup on a quality hard drive, rather than on small external hard drives that have standard disks.
        Practicality: finally smaller than I thought, remains discreet on the desk, all for exemplary performance and a very effective anti-vibration system. Visually good quality manufacturing.
        The price is there, certainly, but with the quality that it must. Very happy with this purchase.

        Effective

        I use it for my backups. I already had a 6 TO in the same line. Great. It is beautiful and fast.

        Great reception - A real pleasure

        Nothing to say except that I am completely satisfied with this product.
        You can buy it with your eyes closed

        Excellent product, well finished and manufactured, and quite quiet for a mechanical disc.
