Network Area Storage (NAS) is going to be an increasingly important thing for home users in the years ahead. The explosion of home media is requiring people to rethink how they store things. A linux NAS gives power users a great way to do this, while retaining the ability to tinker.
A good example is DLink’s DNS-323 linux NAS box. It is a very well priced ($150) linux NAS box that can be hacked and extended. It won’t void the warranty either. You can find lots of users out there that have blazed the trail and done some really cool thing with this box. You can mirror your data in the 2 bay drive for data protection. No, it’s not perfect, but it’s a fun little linux NAS that you can hack on the cheap.
There had been issues with D-Link removing ext3 support. The latest firmware update corrects this issue. Yes, that’s a significant issue for some folks. Speed issues have also been corrected. Yes, it has some cons, but the pros seem to outweigh it for most folks.
