OS3 v4. X single bay My Cloud cannot be updated to OS5 v5. X firmware. After WD terminates OS3 support in April one can still access their My Cloud on their local network.
Q: Will my device stop working if I can’t upgrade to My Cloud OS 5? Will I lose access to my data?
A: Once the services have been shut down, you will still be able to access the device on a local network. However, access through the My Cloud OS 3 mobile app or web app will not be possible. Email notifications also won’t be delivered. Devices that have auto-update enabled will receive a final firmware update to disable remote access and outbound traffic to cloud services. Then, support will end and you’ll have to use the local network to access the device.
No the My Cloud Home is not better. If anything its a step down from the My Cloud line.
There are some things one can do if their My Cloud is sluggish. First step is to disable Remote Access/Cloud Access in the My Cloud Settings section if one does not use Remote Access. Disabling Twonky may also help if one isn’t using the My Cloud DLNA/Twonky media server.
There are further steps one can take using SSH to disable several services (wdmcserverd and wdphotodbmergerd) that tend to help with a sluggish My Cloud or a My Cloud that fails to enter sleep mode. One can search for past discussions on how to stop those services.
