An affordable way to add lots of RAID-protected storage for backup, media serving, or both.

This two-bay box offers a lot of capacity for the buck and streams large files very well, but features are otherwise limited.

Western Digital's MyBook Live Duo is a good entry point into the world of NAS. The lack of active cooling is a concern, though — make sure that it's in a position where it can vent its heat easily.

Our WD Duo has worked brilliantly, the set-up is easy - if a little laboured for the RAID initialisation - and we feel our data is safer than before. Low power standbye also means this drive makes a better home media server than your power-hungry home PC.

If you like the features and price of the single-drive My Book Live, you'll like the Duo even more.
