    Nothing to complain about!

    I waited a bit before giving my feedback. Everything is going really well! The drives arrived very well protected and above all are perfectly functional. I winced a bit at the price, but LDLC was not only the only one offering them, but also one of the cheapest.

    Thanks to this great store.
    My 6 drives ended up in a nice NAS UGREEN DX6800PRO that I highly recommend.

    Best regards to all readers,

    Backup use on a 2nd Synology NAS

    Very happy with the product and its installation for daily backup (on a Synology NAS) of a Synology NAS.

    I only regret that the seller to whom I explained the use did not inform me that Synology would automatically reserve 4 To of space for ITS operation. If I had known in advance I would have taken a disk of slightly larger size (24 To).

    Otherwise, no problem with this DD.

    Still among the best!

    Complete satisfaction so far with this Seagate series, let's hope they last as long as some WD that are already 10 years old!
    Not much noise in my opinion, but that remains subjective.

    Impeccable

    Fulfills its role perfectly. Completely fast and powerful for personal and semi-professional use (storage only of documents nothing particularly heavy)

    For duration

    Disks similar to those found in a data centre. Designed to run 24/7, they are reliable but can be a bit noisy if you do a lot of reading/writing.
    Very good for a NAS.
