Summary: Most cons are annoying, but I wouldn't buy another one of these because it can't backup to locally attached drive.
Pros: - SMB NAS and RAID work - I use mine with a couple 2GB drives in RAID-1 configuration. - Software configuration works.
Cons: - DLNA feature doesn't find many files - Device can't find directly attached USB disk for backup (same USB disk worked with Buffalo TeraStation) - Firmware can't find updates from BUFFALO - Bittorrent browser controls broken from mobile browser.
Summary: This product has never worked right. The advertised remote Internet access is not really there. You are required to use the poorly thought out Buffalo website that supports very few file types with no options to use other file types. Documentation is worse than terrible.
Summary: Beware! Accessing this from a Mac is slow slow slow. We bought the LinkStation for a four-person office. The two Windows machines can access the folders in the share almost instantly. The Macs take about a second per file to list a folder's contents. 200 files = 3 minute wait.
Summary: I got this for Christmas last year, 2013. It lasted about 12 months. It is slowly dying with all 1G of my data on it. I never even got close to the 6TB capacity on this thing. Really disappointing. I'm going to get another NAS, but not Buffalo!
Summary: I wanted to like the LS420. I ordered the 6TB version planning to run it in a RAID-1 configuration to replace my 1TB Linkstation Live, which was nearing capacity. I should have taken it as a sign when I couldn't even use the NAS right out of the box because I had to wait for it to format the RAID...
Summary: Jury is out. Works well when it is up. Trying to use it with my Macs and Time capsules. A lot of time Time Capsules has difficulty backing up and what I discover is that it is off line. Never was able to set it up for web access and I am a computer scientist and Data center manager.
Simpler setup than previous generation but prepare to spend weeks transferring your files on initial setup.

Summary: Looking at the new spec sheets you would think that Buffalo addressed the major concerns about their previous generation of budget friendly, consumer-grade NAS. And you--like me--would be wrong.
Summary: The Buffalo has not been as easy to manage as I had hoped. Also, one of the hard drives in the RAID array failed after less than 2 years and I've lost all of my data that I had back up onto the drive. Fortunately, it wasn't my only backup, but seriously - I have to back up my back up now?
Summary: I figured personal NAS would have gotten easier to setup and faster performing after having first bought a NAS years ago. I guess I was wrong. I was expecting to plug in a hard drive, turn on the unit, and have it work right out of the box just as the quick setup guide showed.
