i work for a company with a 'Mac' department (they are creative/graphics). At the moment they are using an old server mac with a shared Hard drive formatted in HFS+; i would like to buy a NAS with full compatibility with HFS+ partition. I know Synology and QNAP offers compatibility with Mac World (using AFP), but i'm sure they use EXT filesystem as main partition. Is this correct to use Ext partition either for 'existing' Mac datas ?

Thank you!
