Size: 4 TB Vine Customer Review of Free Product ( What's this? )
Western Digital My Book Live Duo 4 TB Personal Cloud Storage Drive by Western Digital reviewed here for Amazon is an Excellent Network attached data storage product. It is very simple to use and consumes very little power ideally suited for home media streaming environments and also doubles as a "Personal Cloud" Storage drive to access your photos and files over the internet.

For your background information, I am an "Enterprise Systems Engineer" by profession and work for a global IT company and I have worked with many NAS and SAN products over the years and fully understand the limitations and expectations from customers who use these product lines. It is a nice offering from WD to combine "Personal Cloud" with a NAS product and honestly I am truly impressed by this My Book Live Duo.

Here are some PROs and CONs first for some quick overview before we get to the nitty gritty details.

[+] Personal Cloud Storage + NAS all-in-one device - Love it!
[+] Plenty fast enough to play Hi-Def Video files over Gigabit Wired or Wireless-N networks
[+] Super Efficient Power usage - Perfect for home environments!
[+] Extremely Silent operation - No FAN design
[+] Capability to have Data Redundancy mode (RAID 1) - Peace of mind!
[+] High Quality Hardware - Pleasing nice looking "My Book Live" series design.
[+] View photos and file with free apps for your iOS and or Android tablets
[+] Connect up-to 7 USB HDD devices using a powered USB Hub for additional shares!.

For those not familiar with exactly what this product is:

This is NOT an external hard drive. It is much more than that. If you need an external hard drive, this will not work for you. This is basically a 4 TB file server, or NAS (Network Attached Storage). You attach it to your network via an Ethernet (CAT5e/6) cable. Plug it into your wireless router or a hub/switch on your network. The box says "Access your files wirelessly!". That's a little misleading. There is no wifi on this. That just means that computers on your network that are connected wirelessly can access it. Lame, but whatever.

Let me just address the complaints from other reviews:

About "Slowness":
First you should probably read the manual. It defaults to "Power Saver Mode" which puts the hard drives to "sleep" after a specified idle time. So if your hard drives are "sleeping" there will be some lag in you initial access time. Some clients view this as "disconnected". So if you need instant, constant access to this, turn that feature off. Second, this is for home/home office use. Don't attach this to a business network and expect good performance with several people accessing it all at once. There is a reason business class NAS's cost $10,000+. This costs under $400. Its a "Personal Cloud Storage Drive". I can copy a Blu-Ray rip to this in about 10-20 minutes. I have a Gigabit network.

About "No fault tolerance":
That is just incorrect. This ships with the drives set up with RAID 0. RAID 0 increases read and write performance, but has no fault tolerance at all. In fact, you are twice as likely to lose all the data on the drives because if one fails, the data on the other drive is useless. However, you can set this up to use RAID 1 (mirroring).

Size: 6 TB Verified Purchase
I have had the 6GB Duo for about three weeks now. Though I love the concept, the instability of the system is cause for alarm. Below is a detailed review:

(+) Great Concept
(+) Online Access
(+) Mobile Apps
(+) Large Space
(+) RAID redundancy (or so I thought - see THE UGLY below)

The concept is great - a personal cloud with fast speed, online secure access, mobile viewing through some nice iOS and Android apps, lots of space, the actual drives are WD Green drives (I have had many and none have failed to date) and the security of Raid 1 redundancy over two 3TB drives. Should one of the drives fail, in less than 5 minutes either drive can be easily removed and replaced (using a matching drive - an easily found and inexpensive WD Green 3TB drive).

I own a photography studio where we run a four-machine PC network. I'm always searching for the best way to efficiently and safely store our material. We are especially keen on ensuring our data is as safe as possible from corruption or loss. We've used a variety of systems and processes over the years, and were excited to see the release of this product as it seemed the perfect balance of security, accessibility, redundancy and speed. Unfortunately, the product did not meet my expectations, as you can read below.

(-) Laggy Speed
(-) Buggy Apps
(-) Limited Control
(-) Drive Runs Very Hot

We received the drive and quickly began migrating our data to the new system. Overall, my initial impression was good. It was pretty simple to setup and the conversion to RAID1 was simply a click of a button. In total, we transferred about 1.2 TB of data in chunks over the course of several days.
