I'm computer literate but not an expert, and I was able to configure this for Raid1 (14 TB total storage) and get the discs initialized and formatted. I had to download the updates from the LaCie website (which is not that easy to navigate, but if you take your time, you can find the necessary info), install the Toolkit and Raid Manager software, and follow the online instructions, and then I had to do some basic internet searches and follow some tutorials to initialize before I was able to format. I used the included software to configure for Raid 1. The whole setup took maybe 90 minutes and I had to be patient and keep looking and reading until I found what I needed. I had a friend who was an IT expert 'on call' in case I needed help, but I figured it out myself. ... MoreI'm computer literate but not an expert, and I was able to configure this for Raid1 (14 TB total storage) and get the discs initialized and formatted.

I had a friend who was an IT expert 'on call' in case I needed help, but I figured it out myself. If you are a complete novice, this might not be the product for you. If you have even average computer skills and some experience installing/removing software, and know how to navigate the Start menu, Control Panel, dropdowns, going into properties, and can read some basic online tutorials to answer your questions, etc, it shouldn't be a problem. It also took me a couple minutes to put together the electric plug, which was not immediately obvious, but don't force the pieces together.I'm using this with Windows 7 and a USB 3 connection, and have had no problems. I like the fact that it has an on/off switch, though it seems to be smart enough to go to sleep when I turn off my PC. I've had it for a month now, and there have been a couple of instances in which it had trouble waking up, and I had to pull the plug and re-start, but it worked just fine after that. You can hear the discs humming from a few feet away when data is being transferred, so it's not totally silent, but the noise is not a problem.The big blue eye seems to have gotten a scrap of plastic trapped inside it during assembly, which looks a little annoying, but does not affect functionality. I'm just using this for data storage and am not editing Blu-Ray, so I don't have much to say about data transfer speed. I wanted a single device with a lot of storage space and redundancy in case of a disc failure, and in that respect this device is just fine.

Thanks for a very easy order process, fast delivery and good customer service

The drive randomly ejects from my Macbook Pro without any warning and gives the error message that says “Disk Not Ejected Properly”There is no rhyme or reason to when the drive will mount. Sometimes it works and other times it doesn't show up in the finder at all. It will be visible in Disk Utility but doesn't allow you to do any function like repair disk etc.When the drive works is quite slow and very noisy!
