Yup, I'm aware of the recent problems Western Digital has with the actual "cloud" implementation of their "My Cloud" Network-Attached Storage devices. I'm not concerned about that - my DSL is too slow for online cloud storage to be a factor anyway. What I'm curious about is whether the WD My Cloud NAS system is a viable alternative to their My Book external portable hard drives for local backups and file storage. WD's My Cloud devices are really affordable now so I'd like to try 'em if they're suitable for my needs. They seem to be much faster than the My Book external USB HDs. Ideally I'd like to accomplish a few things as cost effectively as possible: Archiving my photos (I use Lightroom as my primary editing/organizing software). Making the same catalog and edits accessible to both PCs and any future device. Doing at least some of this wirelessly. My desktop has Acer's Clear.fi for media sharing, which I've never used. I'm wondering whether the laptop can handle this via local WiFi. Or, perhaps, I'm thinking about this the wrong way and I should use both?
