1) Software encryption: this is enabled by the user by adding password protection via the included WD software. It can be enabled or disabled by the user (assuming you have the correct password).
2) Hardware encryption: there is none. However, the RAID is implemented via hardware in the MyBook Duo enclosure. The implications of this design are as follows:
a. The proprietary nature of the hardware RAID implementation means that the individual disk drives CANNOT be read outside of the MyBook Duo enclosure. I believe this is not unique to the MyBook Duo as many other RAID enclosures have the same characteristics.
b. The RAID implementation is the same from enclosure to enclosure. Therefore, a drive created in one MyBook Duo enclosure CAN be installed into another MyBook Duo enclosure and READ SUCCESSFULLY. (As I have two MyBook Duo’s, I have physically tested this.)
c. If the MyBook Duo enclosure fails for any reason, a replacement enclosure will read the disks successfully. The data IS NOT LOST.
3) With respect to temperature, when running continuously for an hour or more (such as when performing a backup), the drives reach temperatures in excess of 55C. While I believe the drives can endure such temperatures, I believe that is hotter than desired. Therefore, I recommend that Western Digital updates its design of the MyBook Duo enclosure to include a small exhaust fan.
4) I have added small, 80 mm (3”) USB-powered variable-speed fans that sit directly on top of the MyBook Duo enclosures to help expel the excess heat from the drives. Even though the fans are small and virtually silent, they are probably overkill as it only takes a minimal amount of extra air movement (the fans are at the lowest setting) to keep the drives comfortably below 40C, even when running continuously.
5) Overall, I am happy with the MyBook Duo (8TB drives). While I do believe the lack of a fan is a non-optimal design decision, it is easy to add an exterior fan that works very effectively at maintaining more desirable drive temperatures.
**** Below is my initial review 1 star.
There is a security chip on circuit board inside the enclosure. If you take out two hard drives, you will see the circuit board in the middle of the enclosure. The circuit board is the controller of two hard disks. When your data goes through USB 3.0 cable, passes the circuit board and stores into hard drives, your data is HARDWARE ENCRYPTED BY THE SECURITY CHIP ON THE CIRCUIT BOARD, which means only the enclosure can decrypt your data. The key used by the security chip to encrypt/decrypt data is stored on the hard drive. If you set up access password, then the key will be encrypted by the access password. Next time when need to read data, have to use access password to decrypt the key and then use the decrypted key to decrypt data in hard drive. The whole process relies on this circuit board, if it dies then you could loss your data. There is NO WAY TO DISABLE HARDWARE ENCRYPTION. It does not matter you set up the access password or not. Hardware Encryption is ALWAYS ON by default and could not be disabled. The only thing you have control is to set up a ACCESS PASSWORD to protect the encryption key.
To prove this, I pulled out two hard drives and connected them to my computer directly. The system could not read my files on the drives, because data is encrypted. My computer does not have this security chip (and it should not), so it could not use the key.
There is a way to read data from hard disk is to insert them into the enclosure of same model, which means you need to spend money to buy another My book duo, but who knows if 5 years later you could still find them on market. WD has several versions of hardware encryption, you could also use control board from My Book (a different product but cheaper than My book duo), but it is basically try and error to figure out the right version.
Let's do some math:
1. Assume WD Red 2TB hard disk Failure Rate is 4%. Then under RAID1, risk of losing data is 4% * 4% = 0.16% (Lose data need both hard disk to fail). Probability of not losing data is 100%-0.16%=99.84%
2. Assume circuit board Failure Rate is 4%. I made this assumption by thinking the quality of circuit board is no better than hard disk. Then 96% of the time, circuit board will work just fine.
3. The probability that system as a whole will work is 99.84%*96% = 95.8464%, since failure of RAID1 and circuit board is independent event. So the system failure rate is 100% - 95.8464% = 4.1536%
4. The "ENFORCED HARDWARE ENCRYPTION" makes data losing probability 26 TIMES HIGHER (4.1536% / 0.16% =25.96) than a RAID1 system without "ENFORCED HARDWARE ENCRYPTION".
5. 26 TIMES HIGHER!!!!!
The conclusion is WHEN THE ENCLOSURE DIES, YOU COULD LOSE ALL YOUR DATA ON BOTH HARD DISKS, Even if the two hard disks are perfect fine!!!!! If you do not plan to spend the same amount of money to buy a second one. The risk of losing data is much higher than the risk of failure of two hard drives, because of the (hidden) risk of enclosure failure.
I will contact WD to figure out if there is a easy way to recover data, hold on.
WD technical support got back to me quickly. They point out to use data recovery software to recover data in case the enclosure fails. Still need to purchase $79 data recovery software. This is technically harder than simply connect to computer and read data directly. But at least, there is some way to work around.
Conclusion: Data recovery is not that easy on these drives, but it is possible. Get ready to spend some money on data recovery software/service.
Revise to 3 stars.
*****Below is the response from WD:
Thank you for contacting Western Digital Customer Service and Support. My name is xxxx.
In regards to your case, the data can be recovered with a data recovery software. Since you were running RAID 1, the data should be available on both drives. Your next step is to connect one of them to your computer through sata and use a data recovery software to recover your files.
After removing the drive from the enclosure, do not put it back inside, ever again. That will reconfigure the drive and therefore you'll loose your data.
Although we do not have any specific software that we can recommend, many of our customers have had great success with Ontrack's data recovery software.
