It's the default for new Synology devices, and has been for a while. I suspect others are using it in a similar situation for home-grade NAS and up into the prosumer end of the market.

I feel like Btrfs is probably going to be well tested here, but I wonder how many of these users are diagnosing Btrfs problems when they occur? It's going to be more evident to some people, and you have to assume that some of the vendors are competent, but this is against a backdrop of people throwing this kit away or starting from scratch versus performing a root cause analysis.

I've personally been running this since it was stable on my DS1515+. I haven't had filesystem issues yet, but I make sure my important stuff is backed up elsewhere. A local backup like this is convenient for faster recovery in a lot of situations though which is why I keep it. I've SSH'd to the device and played around a little, but I fear I'd hit something proprietary, if the worst recovery situation occurred and I had to get everything from the DS1515+. If it was just an Ubuntu box I wouldn't have those fears, but the Syno NAS package is compelling.
