1 out of 5 eggsNot impressed

Pros: Shipping was good / quick (newegg).
Setup was simple (easy to follow steps)
Packaging was good and the unit arrived w/o any issues.
Device is a good size and is reasonably attractive.
Device has a management page with a reasonable number of management and configuration options as advertised.

Cons: The purpose of using a Mirror Raid NAS unit is to backup personal files and folders. Pictures, music, etc.

I found after very little use (specifically time) the device performance tanks after backing up my files. I have a large number of images, songs, and applications. However the device takes upwards of 2-3 minutes to respond in the Windows Shell (appears to hang, but the LED lights indicate it's really busy). The CPU is pegged at 99% even after days of NOT having accessed it. Logging in / shutting down / rebooting the device can take minutes to complete.

I'm unclear if the unit is defective, is a firmware issue, etc. I've tried disabling streaming and all capabilities I'm not using but it makes no difference. Copying a 20kb file to the device took over 3 mins to complete! I paid too much to have this experience.

2 out of 5 eggsSo far- performance is disturbing

Pros: ease of setup

Cons: so far slow.

Other Thoughts: Main concern for me is some processes that are running on the device which are hogging CPU usage. Despite all my cloud and sharing services turned off (this nas is for data and to work directly off of), there is a wdphotodbmerger process that is consuming 50% of the cpu or more whenever I seem to need to work on things. I have owned a 3tb and 2tb my book live prior and performance allowed me to rename files and save small documents lickety split. At first I thought this was due to the raid mirror setup. But after seeing the processes running and their cpu usage and doing some online research, this is a known issue and a very debilitating one considering performance is tantamount for me.

Let me turn off this service, or make it not run when I have sharing disabled. Supposedly its generating thumbnails for teh wd2go/cloud apps. Which I don't intend to use.

Maybe I am wrong though, maybe its the NAS mirroring causing this slowdown? But its much slower than the my book live I was working off of before and performance was acceptable. I upgraded to this reading that performance was the same but this offered the data protection of raid. WD if you are reading this, please help.
