1 out of 5 eggsTerrible product and support

This review is from: BUFFALO LinkStation 420 6 TB 2-Drive (2 x 3 TB) High Performance RAID NAS Personal Cloud Storage and Media Server - LS420D0602

Pros: If you hard power it, mine at least, will last 4-8 hard powers. Unfortunately if you have the latest firmware Buffalo Tech support can't do anything for you.

Cons: If you want it to work for more than a month with the power on then you are looking at the wrong company. It will freeze and when you convince yourself to pull the power and plug it back in hopeful that it will still contain your information....good luck.

Other Thoughts: Tech support consist of updating your firmware because that's the cause of all problems. When that doesn't work have fun waiting until they contact you AT THEIR CONVENIENCE.

5 out of 5 eggslove my NAS

This review is from: BUFFALO LinkStation 420 6 TB 2-Drive (2 x 3 TB) High Performance RAID NAS Personal Cloud Storage and Media Server - LS420D0602

Pros: This Buffalo drive gives me a good feeling as a RAID mirror. I just bought one for my son as he needed a NAS. He's had it about 3 weeks and loves it. I've had mine over a year. It automatically comes on when I turn on the computer (after installing the driver) and goes to sleep when I shut down. Now my wife and I can keep all of our files in one place and both access them. I keep all of my important files and don't think I will lose them. My 1TB came with 1 HDD and I added another. My son's is the 6TB as a 3TB RAID and came with 2 installed HDD.

Cons: none!
