I have a library of over 26,000 songs but realisticly listen to only 5,000 or so. I decided to load these songs on a NAS drive to remove Airplay from the streaming path. NAS drives are quite pricey ranging from $300-$600 or more DISKLESS. So add another couple of hundred to install a decent sized SSD.
I tried connecting an excellent SK Hynix 1Tb USB drive to my router USB port but there is an outstanding problem with Sonos S2 processing music libraries from a USB connected drive. Ethernet drives work fine and don’t have this problem.
I calculated I would need approx 250 Gb to store 5000 FLAC files but the investment was over $500. for a good, reliable NAS. After a lot of research I decided to invest in an Amber X drive. I have no interest in using this to manage photos and videos or use any of the other available applications. Just music streaming.
It has a very small footprint with both Ethernet and USB ports. The drive size is approx 480gB and I loaded all 5,080 FLAC files with room for another 2500 songs if needed. Setup was ridiculously simple and I now stream music flawlessly without the Airplay bugs, delays and other baggage. I now control my music stream without using my phone, iPad or computer. Just Sonos voice commands (sweet).
The Amber X was $169.00 for the 512Gb version (really only 480gB) and more than worth it for my NAS solution.
Cheers!
