Input:
Question: When 2 SATA drives are installed, is the RIAD setup automatic or is there an option to operate the LinkStation with 2 separate disk drives?
Document: I think I'm going to give up on this one for now. I started out with the one-disk option. It booted it up to Emergency Mode, which I discovered in the firmware notes would happen on initial one-disk setup, but the firmware is supposed to have fixed that. Updating the firmware was a chore, and I'm not exactly sure how I managed to finally get it done, but it made it to 1.11.After rebooting I get the flashing red light.
We're pretty frustrated at this point, because I bet this is a great product if you can get it up and working. We installed drives into the enclosure with no problem and connected the Linkstation cable to our network switch and applied power. The lights went through the sequence that is cryptically depicted in the Quick Setup Guide (why not just use words?). We then inserted the CD and ran the Install.
I guess they have better things to do, like training customers not to use email support.I am also kind of annoyed at Buffalo because of my earlier NAS. When I installed that LinkStation, I set it up as a RAID 0 to maximize capacity and have been living under the assumption for 5 years that the disks were &#34;independent&#34;. In other words, if one disk died, what was on the second would still be readable.
I must say that the BYO disk approach is great in the larger setups, as the flexibility it offers combined with the cost savings (that multiply as you add drives) makes it hard to match by OEMs. With a two drive setup, honestly I prefer the OEM approach. They beat what we have here in terms of simplicity, polish, and often cost.
The setupguide was easy enough to follow, but I wish there were textinstructions as well. During the initial setup process, I had a white led blinking and somered led blinking for a while, and then the lights turned solid white. Then, I installed theNasNavigator 2 from the CD, and I was able to setup thefeatures I wanted.
The only metal is the screws and one metal flap to ground the drive. So for Quality of Construction: 1 Star.I went ahead and installed 2 new 3TB Drives and their software. It took nearly 2 Days to complete the RAID configuration for such large drives, but, that is probably fairly normal. Their Software gets 1-Star. TERRIBLE!! It wouldn't upgrade the firmware and it doesn't configure the permissions correctly.
There, I try to format the disk in the web interface's advanced settings with the XFS option, the only one it gives me, and after a few moments I receive a message that due to an error the process can not be done.I have no idea what the button on the front of the unit is, I assume reset. Nothing is clearly documented. Even the firmware notes say to connect directly to the unit.
From the "File Sharing" tab, shares, users, groups, protocols and permissions can be set up.The "Drives" tab shows the installed discs, the RAID setup, connected USB drives  and the ability to turn RAID scanning on and off. A word of caution, the factory default is RAID 0, which does not provide any redundancy, but instead offers higher performance.
The Synology and ReadyNAS also have apps to make remote access easy and apps to play media files and access shared directories remotely - and for the Synology without even going through a cloud. The Buffalo app is not as intuitive or feature rich as Plex (used on the ReadyNAS) or the Synology apps (separate apps for music, video and files).After setting up two other NAS, I found the LinkStation setup the most unclear. Things like web access are not straight forward to figure out.
The Buffalo LinkStation 420 is a simple-looking two-drive NAS with two 1TB Toshiba (in my copy) drives installed, configured as a RAID0 array. RAID0 gives you the benefit of combining the capacity of the drives and improving performance by splitting access across the drives, but it has the big disadvantage of no redundancy. With a RAID0 array, if one drive fails, you lose everything on both drives.The 420 allows you to reconfigure as RAID1, otherwise known as drive mirroring.
Answer: You can set the disks to be seperate drives if you wish,  details on doing this are under the section titled 'using JBOD'  in the managing storage section in the manual.
