We’ve been using the Buffalo Linkstation WVL NAS for just over two years now and it’s been rock solid despite running 23 1/2 hours a day (I have it set up to effectively reboot around 3am every day). Recently however we’ve had a few disk errors (from disk 2), which seem to be repaired when the diagnostics are run, but then reappear later and which interupt the backups that I run monthly.
We’ve also got a looming capacity crisis with the system cresting 85% capacity. It seems clear it is time to either upgrade to a new system, or to upgrade the drives inside to increase our capacity.
I’m going to have to do some reading to make sure I can slot 4tb drives in the Linkstation, as I am not prepared to spend $1K on a new NAS arrangement right now.
