Hello,
I recently bought a brand new Western Digital WD40EFZZ (WD Red Plus 4TB, CMR, 128MB cache) for use in a NAS with omv installed. The thing is that i use my 3.5 hdds with a quality hdd enclosure/rack via usb 3.0 because the pc is small and it only has space for two 2.5 SATA device.
Before putting it into production, I performed some tests and would like an expert opinion.
I did a CrystalDiskInfo, where Reallocated Sector Count, Current Pending Sector Count, Uncorrectable Sector Count were all 0, Power-On Hours same.
After that i did a HDDScan – Full Surface Verify. The results were : Bads: 0, No UNC errors, Distribution mostly <5ms, but :
~200 orange blocks <500ms
1 red block >500
