Review on 🔒 Reliable Performance: Western Digital 4TB WD Red SMR NAS Internal Hard Drive - 5400 RPM, SATA 6 Gb/s, 256MB Cache, 3.5" - WD40EFAX by Mark Hanson

Be aware of the ongoing Western Digital scandal that is secretly replacing the underlying technology of PMR with SMR. SMR drives write slower and cannot re-cluster non-SMR drives. Western Digital tried to cover it up and cover up the truth. Some other hard drive vendors do the same, but WD has applied this to its NAS drives. Not only is this a scam, it actually causes crashes in your NAS. You can search the internet, there are many websites that report this with all the technical information.
