    RAID Group  

    To ensure data security, system stability, and storage performance, the maximum number of drives for a single RAID group is now 16 (applicable to RAID 5, RAID 6, RAID TP, and subgroups of RAID 50 and RAID 60). Nevertheless, users can combine multiple RAID groups into a large storage pool that contains more than 16 drives, using RAID 50, RAID 60, or RAID 10 as the RAID configuration. This enhancement will only be applied to new RAID groups. All existing RAID groups and storage systems will not be affected.

5 thoughts on “Qnap TS-855X NAS spotted

  1. What’s the US price we can expect for this NAS? Any idea of when it may be released.

    I assume that this unit may replace TS-873A and it may be within that price range ($1,050)
