Seriously, if you have a need to get to your data reliably and instantly, i think floppy disks with the protective cover cut off is most areas would be more reliable than this drive.
Please note, this is my experience with customer service and this drive since November 2017, until June 2018. This drive ran me just over $300 and while the size and speed when it works is good, it's so unreliable, i think i would have better odds wrapped in Chum swimming safely off of seal island than relying on this drive for my data to be available.
issue 1 - the drive will not show ONLINE if you're not logged into the MYCLOUD system. No idea why, but if you don't log in (manually) from the Systray icon, you're drive will not be accessible.
Issue 2- If you reboot the PC, login is required, again. it may randomly show back up as available at some point (10 minutes, an hour, who knows). It's a HORRIBLE design
Issue 3 - if you want to create a Share, you can't just have the drive name\share. (if the drive was named "John_ext_drive" the share would be \\John_ext_drive\ShareFolder). the share it creates is about 64 alpha-numeric characters long. It's INSANE. So if you want to give someone access to that new Share, you have to copy that long path, and send it to them via EMAIL (because you will never remember it) in order for them to access it. But don't lose connection from the Agent in the Systray to the drive...or it fails.
Issue 4 - There is no granular security on any of the folders. If you setup the drive, you are the OWNER of the drive. You can grant people access, but only by using EMAIL to grant it. Meaning when you create a shared folder for little Suzie to save her homework to, you have to create the folder and assign it to an email address to send the very long share link to.
I'm not sure of the person who designed this horrible software/interface for this drive, but they have no idea how people really use drives. the ONLY scenario this could possibly make sense is if i was giving total strangers access to this drive (made for personal use by the way) for a fee where they can access just the folder i designate, while only being on my network, but not anyone i want to include in anything else....all the while hoping the WD Systray agent doesn't fail.
Avoid this drive. The MyBookLive was a better rendition of a home drive that may have shares created easily, and with granularity as well as identifying possible types of data for organization and (possibly) QoS to help streaming movies not be impacted by someone looking at word documents from another folder.
I can't click the "I DO NOT RECOMMEND" button strong enough for this drive, without breaking my mouse.
