> WD mixed both CMR and SMR for the WD Purple, an a few other models too. Could you point me at an example of a SMR-based WD Purple drive? Is this just a historical thing? As mentioned in my other comment, the spec sheets [1] say all (current) drives are CMR. > Actually the Purple only has one distinguishing characteristic. An ATA command to skip bad sectors instead of trying to read/write repeatedly. This is great for an NVR but it's not mandatory to use. I'd also be interested to see a reference / details for this.
