i just have a basic question:
i have a QNAP with 8 disk WD20EFRX-68AX9N0 - 80.0080A (2TB)
and i have 3 of them in abnormal (pre-fail maybe) and the virtual disk (RAID-5) change to “only READ”
i want to replce this 3 disk…what are my options?
- i must buy exactly the same model with same firmaware?
- same model and upgrade frmaware (how i do that…dont see that option in QNAP)
- another 2TB model?
