i also have an external hard drive (500 GB) and a squeezebox 3. i store my cd's via wav on the drive. i have over 400 albums and am using only a little over half of the 500 GB.
many people feel flac is instinguishable from wav. flac is also considered a lossless format. it's works in the same way as a zip file. i have not done any listening test of flac vs. wav. i chose wav for peace of mind more than anything. with wav, i'll never have to worry that i'm losing any music, resolution, etc.
the advantages of flac are that it allows for metadata (artist, album, track title info, etc...) to be written to it. wav does not allow for metadata, but i bought a program (tag&rename) which allows me to write or obtain from the internet the same type of metadata onto my wavs.
