How to upgrade WD MyCloud OS3 with OS5

How to upgrade WD MyCloud OS3 with OS5


Yes, this is a popular question. If you can not install OS5 on your WD NAS then they will disable internet access from January. You need to upgrade to WD PR/ EX Ultra series or change a brand.

The most popular upgrade choice is Synology and Qnap models with Realtek and Celeron processors inside. You also get new DDR4 memory and transcoding chip for remote video streaming. Qnap and Synology also have their own computer and mobile apps unlike WD (They rely on third part y such as Acronis etc).

Here are the upgrade options

DS218play / TS-230 with Realtek CPU. Good for backing up and remote access. Not as good for third party app use.

DS220+/ DS420+ / TS253D/ TS-453D. Good for first party as well as third party app use. Has no limitations on apps and functionality you can use. Fast enough to use for multi user environments and wide range of file formats.
