THis is in NO WAY a defense of WD, just an awnser to the question "Does NAS drive arrays exist outside of a RAID?"
RAID has several levels.. Any RAID that uses Parity will have a problem with SMR, but Mirror and Striped array probally will not
A common use case is a 2 Disk Mirror NAS for SMB.
Further NAS manufactures like QNap, and even WD do make single disk NAS Appliances
However the WD Red line is branded for NAS upto 8 drives, Most likly that will be a RAID5 or 6 array making SMR not usable in that configuration
- prirun 7y agoMy understanding is that SMR drives fail because the write load is continuous for a long period of time and overwhelms the background process organizing the data for efficient SMR writes. In a 2-disk mirror (RAID1) rebuild, all data from one drive has to be copied to the other drive, which seems likely to overwhelm an SMR drive. So it would seem to only work in a RAID0 array (concatenated drives - bad idea) or JBOD NAS setup.
