Western Digital is releasing the CMR-based Red Plus series NAS HDDs. This series assures ZFS compatibility for NAS, one of the features that were supposed to be a part of Red sub-branding. This is the action WD took well after being called out for switch-and-bait of WD Red models from the EFRX which used SMR to EFAX models between 2TB-to-6TB that used the lower performing and lesser reliable (for NAS) CMR technology. It all started with a lack of clarity from WD which kept defending its stance after the crowd-sourced evidence of NAS-specific issues.
US-based class-action lawsuit experts ‘Hattis & Lukacs’ are inviting those who are affected by reliability issues consistent with SMR-based HDDs. This started with the problem affecting SMR-based Red series. Many NAS users with this HDD found unfixable problems with one of the two models of the WD Red series HDD. The earlier one used CMR, while the latter used SMR drives. WD did not disclose the recording method until the fallout of this problem.
