NAS drive for cold storage/backup?

Honorable
Are there any disadvantages in terms of reliability of using an NAS drive (not an NAS build, just a HDD labeled for NAS use) for cold backup storage or as an HDD?

The HDD in question is HGST Deskstar 6TB drive (H3IKNAS600012872SA), which is currently discounted to within about $10 of a WD Blue 6TB drive.
 
Solution
nas drives are just better at linear reading/writing then a normal drive (better at random access) they are designed for large files storage (video, music etc)
aside that none.

Thanks, I went ahead and bought the 6TB NAS Drive, now waiting for the enclosure to come in.

I think this will be the last 6TB drive I buy though, gonna go with 3TB blues after this (better price per TB), these are for backup and storage purposes.
