WD My Cloud 4TB Personal Cloud NAS

Update 2: Wellll. The Buffalo Linkstation Pro Duo with the two 3 TB disks in a RAID 1 mirror is awesome. Did everything it said it would, and behaved as you would expect it to right out of the box, first time. Is clearly more Mac friendly than WD products I tried. The iPhone app worked first time. Its for sure not as GUI as the WD stuff, but it works. WD stuff did not, GUI or not. If you're even a little bit of a geek and READ the directions, you will for sure figure it out. Solid, solid. solid. Having it back itself up to an attached USB disk, running a 250 GIG time machine backup, accessing it remotely and also copying folders to it ALL AT THE SAME TIME and it does not hiccup. Sent back all others that I had tested and am happily finally stopping jacking with this stuff after about 4 solid days of failures with WD products.UPDATE 1: I ordered the WD EX2 and after reading reviews more carefully chickened out and cancelled. Look deeper, and customers had same sort of problems. Decided to bite the bullet and ordered the WD EX4 and again, after reading more and more reviews both on and off Amazon, cancelled that one too.Did more research and wanted to get the Theacus NAS and ordered and cancelled it too after noticing that the iPhone app was last updated in '10 or '11. Scared me. Then looked hard at the Synology product line and looked like to me their iOS apps were not strong, IMO. Actually, wasn't even sure they existed.Finally read more after 4 hours or so of this punishment (Amazon is going to fire me as a customer) and settled on the Buffalo LinkStation Pro Duo with 2x Seagate 3 TB drives that I plan to set up in a Raid 1 Mirror. Plan to keep my WD 4TB External MyBook drive mentioned earlier and use it for backups of the RAID.I read carefully and Buffalo has good iOS apps for both remote access and remote management. Current with iOS7. Also support the Apple AFS protocol (and others) AND says it supports direct Time Machine backups. Specs on drive are great... we'll see. I will report back if it all works in the Apple environment as it is advertised to. Price was right, that is for sure.Original Review: I have a good Cable Business Class Internet connection, Apple AirPort network system comprising of a 2 TB Time Capsule Router and several Extreme's in repeater mode around my house. My MacBook Pro computer with SSD is never more than 50' away from an access point.My project was:1. Moving 15 GB of data from a local Google Drive folder.2. Moving 15 or so gigs of local data on my SSD drive3. Pointing Time Machine backups to MyCloudand if that all worked...Getting my wife's computer and kids pointed at the MyCloud too.Moving data using the iOS or Win (I have a VirtualBox Win Install on my Mac) WD client application was pretty good. It however has its limitations (for instance, cant handle Mac Numbers file format and has limited cut-n-paste and drag-n-drop compatibility). Using Finder to move data when mounting the device, is so painful it is useless. Even when directly connected by CAT5 as support suggests. Its just too slow. If you're using a Mac, you've got to be able to use Finder.Time machine backups of 250GB takes 2 days and fails often. Time Machine will not use backup as it will not pass verify tests.AND, to add insult to injury, the WD 4TB MyBook that I have connected to it by USB 3.0 (Direct Connect from MyCloud to MyBook) takes 20+ hours to move 280 GB of data. That is crazy. AND, it corrupts often. USB 3.0 is a lightning fast protocol. It should take way, way less time.I am returning it and buying the WD 4TB ex2 BECAUSE the software interface and iPhone app for the MyCloud series of drives is so cool and so nice, I'm desperate for it to work. If it were to do what it was supposed to do it would be awesome. So instead of saving the half or so on the consumer model, I'm getting the entry level "expert" model and seeing if that will work. If that does not work, paying 4x the price for the ex4 8TB will probably be too much of a jump for me and I will switch brands.There are things that I could do to tweak the consumer model in this review according to support via UPnP settings and other tweaks...but the USB 3.0 direct connect is a deal breaker even IF I were to get the network part to perform acceptably. It will be making backups pretty much all the time and that interferes with its performance too much.ALSO it should be noted that the relay service at WD that gives you access to your drive remotely is in the middle of issues (been going on for a week or so according to WD) and that COULD be affecting the traffic going to the drive. I'm sure they will get it fixed...thats not my beef. AND when you call them, they say it has nothing to do with local performance. Oddly, the performance from my iPhone app over 3G network was acceptable.If you're moving bigger data around on a Mac environment and your planning on doing Time Machine backups to this drive, you'll have to have a different experience than I have had to be happy.Certainly open for suggestions.
