Indexing Music Library

Well, I’m still of the opinion that scanning data for individual tags and storing them in a list is a larger task than just copying a file (dependent on the memory where the data is written). One is looking at multiple data points for each file, and storing it, the other is a low level command execution of the entire file. 

I have a 1.9tb library of uncompressed .flac files in a single share with 55/60k tracks. An S2 index request, usually on an associated Play 5, for an:

• Album addition - a few (+/-) miniutes
• Sub level folder rename (+/-) 20 miniutes
• Top level (ie. a share name change) maybe (+/-) 30-50 miniutes (ish 🤔)

I may be a little vague and suffering from a slightly optomistic memory, but I would expect a total share name change to be done in the time it takes to have a P, make and eat a sandwich, check social media, maybe make a call or two and pick my nose for a while 😋

(for comparison, a full backup to a USBc connected drive can take a LOT of hours...)

For comparison on a similarly sized library… On my previous NAS, S1 took 5 minutes for an update and S2 took 55 minutes. I just set up a new NAS and now S1 takes 1.5 minutes and S2 takes 15 minutes.

What kind of drive, and connected how? Gen 1 or 2 Play 5?

My library is on an SSD, Raspberry Pi host, and 100mbps Ethernet. A lot smaller, all FLAC, and seemed quick when last tried.

I may fool with it, try my Arc Ultra and then a Play 3 and compare speeds.

Can you change your Associated Product or are you unplugging to force the index to be done on the only powered Sonos Room.

Access to the music library is read only. There’s no need to worry about drive write times.

Synology NAS running HDD in a RAID configuration. Dual 1000mbps ethernet bond with Sonos on 2.4/5Ghz auto selected Wi-Fi (via 1000mbps ethernet) using a NAS user with read/write access (which now seems to be a requirement)...

Oh, not Play:5 but Sonos Five as associated speaker 🙄

Not sure what mbps the Wi-Fi network runs at but have never noticed any issues and it reports well…

(and full backup to a similar spec networked NAS via Wi-Fi takes some hours too...)

Wow!  I have 46,000 tracks.  Index takes around 10 minutes.  Of course that’s an index looking for new music I just added.

My new NAS is a Synology DS225+. The sonos NAS user has read only access here.

But read times, particularly on a low memory and slow RPM Green drive, can be an issue and a SSD is usually faster for that, even with a speedy hard disk or NAS.
