I have all my CD's ripped to FLAC file per album. Each FLAC file varies from 200MB to over 500MB. They are all stored on my NAS which has a Gigabit connection. I think because the NAS is rather full, it writes at a speed of around 3MB/s whilst it can read at 20MB/s.
I'm attempting to Album Art to each FLAC and over the network, MP3Tag can take up to 20 minute to write the image file into the tag for just one album. If the file is stored locally, it's just a second or two.
Is this expected? Is there an alternative that would be faster.
If not, I may transfer all files to my PC one night, write the images to them, then transfer them back to the NAS the next night.
