I have some very long hex strings that I need to store. Actually, I store them in a varchar(max) field. I tried redefining the field to varbin(max) and it works as well. My question is: which method is optimal in terms of space? My thought would be that, given that the strings are not Unicode, 1 byte per character is used in varchar. Therefore, I would think that both methods use the same amount of storage. Can anyone chime in and confirm whether I might be neglecting something in my reasoning? Thanks!
