False. Various sized drives come with various size caches. You can’t instantly detect SMR/CMR by cache size. Error recovery controls: WD Red™ NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. 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. Reliability: Desktop drives aren’t typically designed for the demands of an always-on NAS environment. WD Red hard drives are designed to perform under tough conditions encountered in high-intensity 24x7 multi-user NAS environments.Few of them are SMR and other are CMR drives. You can identify them here https://nascompares.com/answer/list-of-wd-cmr-and-smr-hard-drives-hdd/ Compatibility: Unlike desktop drives, these drives are tested for compatibility and optimum performance. The easiest way to detect whether it is a SMR drive is the cache size. Old drives (WDx0EFRX) had 64MB cache whereas new

RAID Ready: WD Red hard drives are engineered with RAID error recovery control to help reduce failures within multi-bay NAS systems, unlike most desktop drives that are configured for generic use. It is important to choose a drive purpose-built for RAID-optimized NAS systems to ensure optimum performance and preserve your valuable data. Take the following into consideration when choosing a hard drive for your NAS: For those googling for the answer whether combining WD EFRX and WDEFZX (WD40EFRX and WD40EFZX in my case) would be safe.Western Digital’s exclusive NASware™ technology fine tunes drive parameters to match NAS system workloads which helps increase performance and reliability.

Sharing is caring! Share SMR HDD with NAS community! Get a notification when something new is added to the list! I will replace the broken drive with the WD2002FFSX and leave the currently working WD20ERFX (until it will eventually fail). Western Digital has heralded a positive shift in its approach to users of shingled WD Red NAS drives, via a short statement on the company blog. As described in our recent article Western Digital admits 2TB-6TB WD Red NAS drives use shingled magnetic... The first indicator to detect whether it is a SMR drive is the cache size. But do look for letters EFAX in the serial number this would mean SMR. Old drives (WDx0EFRX) had 64MB cache whereas new replaced drives (WDx0EFAX) feature 256MB. You can also read the serial number on the disk itself and compare it to a table bellow.

Thank you!

Do right by your NAS and choose the drive purpose-built for NAS with an array of features to help preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS: 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. 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.
