I bought a 'LifeBox' some time ago in Maplin. It's a rather noisy device typical of the generic stuff coming out of China.
It did what is was supposed to do but with these limitations:
1: Could only use FAT32 file system...no videos greater than 2gb in size.
2: If you formatted it as NTFS, while you could use it as a backup device, the media player would not see any files.
3: Specific directory names were needed, e.g. MUSIC, VIDEO, PICTURES or the media would not be recognised.
4: It takes ages to boot up.
5: Only the first 12 characters of a track or album name displayed.
6: Navigating a music library is a complete PITA.
7: Did I say it was NOISY?
Try before you buy.
