    Non-zero drive reconnection count on new HDD

    So my older backup NAS, a DS412+ that I repurposed as a backup NAS after upgrading to a newer DS1015+, was starting to run a bit short on space.

    SSD Volume and HDD Volume on same NAS

    Are their any issues running a pure SSD volume and a pure HDD volume on the same NAS, or will the presence of an HDD volume drag the SSD volume down to spinning rust speed? Eg: Storage Pool 1 / Volume 1 = SSD-only array Storage Pool 2 / Volume 2 = HDD-only array

    DS215j HDD Replacement Recommendation

    Hi All, This has probably been answered many times before so I apologise for asking again. Background : I have a DS215j with a single 4TB Seagate Drive which I thought would be future proof when I purchased it 4-5 years ago. It's storage capabilities are far greater than I will ever (ever)...

    Hyper Backup to USB HDD takes up most resources of NAS :(

    Since I started anew with a Full NAS backup task to a USB3 HDD I noticed this behaviour again.
