Would it be a good idea to take my 4-bay NAS with me on the plane?

>work sending me to the US for 3 years from the UK
>have a diplomatic visa
>want to take my NAS which has about 30TB of media on it

No point encrypting as they'll make you unencrypt it or kick you out. Don't want to use cloud storage to re-download when I get there. Don't think I have enough buffer to re-download everything from PTs. Figured it's better to keep it with me on my carry-on rather than ship it.
