April 15, 20206 yr Statement from WD: All our WD Red drives are designed meet or exceed the performance requirements and specifications for common small business/home NAS workloads. We work closely with major NAS providers to ensure WD Red HDDs (and SSDs) at all capacities have broad compatibility with host systems. Currently, Western Digital’s WD Red 2TB-6TB drives are device-managed SMR (DMSMR). WD Red 8TB-14TB are CMR-based. https://www.computerbase.de/2020-04/wd-red-festplatten-smr-ohne-kennzeichnung/ What the hell... 😡 Edited April 15, 20206 yr by Zonediver

April 15, 20206 yr If it's an EFRX yes, if/when they release a WD40EFAX with 256MB cache it will likely be SMR.

It is an EFRX with 64MB cache but the disk behaves really strange. When it goes to sleep, it makes a scratchy sound. Then suddenly I got artifacts in movies and TV series and yesterday I had stutter and sound interruptions. But the SMART values look good... maybe a "mechanical defect"...
