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. There?셲 a leading edge WD Red drive for every compatible NAS system to help fulfill your data storage needs. Western Digital partners with a wide range of NAS system vendors for extensive testing to ensure compatibility with most NAS enclosures. I am in the looking to replace my WD Red 3TB drives with WD Red Plus 6TB drives (making sure CMR tech is used). Now i noticed that a new WD Red Plus line has entered the market in 2021, namely the EFZX series with 128mb cache instead of 64mb cache currently used by the EFRX series. Compatibility: Unlike desktop drives, WD Red hard drives are specifically designed and tested for NAS and include NASware™ technology which fine tunes drive parameters to match NAS system workloads for optimum performance.

The specification can be found here Western Digital WD Red Pro NAS Internal Hard Drive HDD 3.5" | Western Digital Error recovery controls: WD Red™ NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system.Perpendicular magnetic recording (PMR) and shingled magnetic recording (SMR) are technologies used to physically store bits of data onto a hard disk drive (HDD). For HDD manufacturers, one of the most important concerns is areal density, which is the number of bits of data that can be recorded onto a magnetic disk. Areal density is measured by the number of bits or gigabits per square inch, with the higher values allowing for greater storage using the same amount of disk space. SMR offers larger drive capacity than the traditional PMR because SMR technology achieves greater areal density. False. Various sized drives come with various size caches. You can’t instantly detect SMR/CMR by cache size. The primary difference between the two 2TB CRM drives is the rotation speed (7200 vs 5400). Not sure if that will be an issue. Tend to doubt it; although performance will likely (Don’t really know) be limited to 5400 rpm performance if you have a Raid 1 configuration
