Charlie wants to rip his CDs to a memory stick. Should he partition it since it's 128GB? Leo says why not just get a smaller one? Or, better yet, rip the CDs into higher quality. If he's going to do it, do it once. Charlie should rip the CDs into FLAC, which is a lossless format, and preserves 100% of the CD quality. MP3 doesn't do that, neither does AAC. FLAC is identical to CD quality. Use that for archival storage and then he can convert down from there to a USB drive.
Scott has gotten some interesting results from the high resolution audio test he was conducting on AVS forum: 80% said they could tell the difference. Leo says that's unlikely and some may have cheated. Scott agrees and says it's more likely that people can hear the difference between MP3 and uncompressed.
