Even of WD's official page for WD Reds, they are still advertised for RAID: https://www.westerndigital.com/products/internal-drives/wd-red-sata-hdd#WD20EFAX |

For instance : |
| 4 |
● Reliability: The always-on environment of a NAS or RAID is a hot one, and desktop drives aren’t typically designed and tested under those conditions like WD Red™ is. |
| 5 |
● Error recovery controls: WD Red™ NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. |

Designed with SMR technology for workloads associated with personal and home office, such as storing, archiving and sharing, in RAID-optimized NAS systems with up to 8 bays. |

This isn't just NewEgg or Amazon puting outdated information on the product page, it is WD still advertising today that the SMR WD Reds are appropriate for RAIDs, while they are, in fact, not. |

Regarding the blogpost: I don't think a blogpost is appropriate for a company to correct information about deffective product, when the advertising for the said product remains uncorrected. |
| 14 |
Nevertheless, even in their blogpost, they aren't being entirely honest, since they still claim that WD Reds are appropriate for RAIDs: |
| 15 |
|
| 16 |
"In a RAID rebuild scenario using a typical Synology or QNAP (non-ZFS) platform, WD Red DMSMR drives perform as well as CMR drives or show slightly longer RAID rebuild times, depending on the condition of the drive and extent of rebuild required." |
| 17 |
They double down on this further in the blogpost. |

|
| 19 |
From some quick research, this is only true in a RAD1 array. In any other type of array, it is sometimes impossible to expand or rebuild the array with SMR drives. |
