    Hey all,

    I'm looking to add a couple more disks to my array, I currently have HGST HDN726060ALE614 drives.

    I'm struggling to find drives with this exact model number, but there are plenty of HDN726060ALE610.

    Looking here: https://trcdatarecovery.com/news/understanding-hard-disk-model-numbers-hitachi

    HTS545050B9A300 = 500GB, SATA 3Gb/s

    H = Hitachi
    T = Travelstar
    S = Standard (vs E for Enhanced availability)
    54 = 5400 RPM
    50 = Full capacity — 500GB
    50 = Capacity this model, 50 = 500GB (40 = 400GB, 32 = 320GB, 25 = 250GB, 16 = 160GB, 12 = 120GB)
    B = Generation code 9 = 9.5mm (the height of the hard drive)
    A3 = Interface - in this case SATA 3Gb/s
    0 = Reserved by the manufacturer
    0 = Feature code,
    0 = None - in this series a 1 indicates that the drive supports Bulk Disk Encryption, this can have a different meaning for different generations and families of hard disk drive.

    Based off the above, that shouldn't cause any compatibility issues? I just need a bit of a sanity check before I lock in some new drives and bunker down for a rebuild of my array.

    Best contact WDC directly as that last "4" could be anything and I'm guessing it might be non-standard sector size like 520 or 528 bytes or worse perhaps denotes even a shingled drive although those tend to have 256 MB buffer sizes for rewriting which this doesn't have.
