Generally the enclosures are just that, enclosures that offer the connection. There are exceptions though where enclosure does something more. Some enclosures do encryption and some just use the same controller for single drive and multidrive and your one drive is actually set up as a 1 drive raid array in which case you may have data slightly shifted to accomodate the headers for that. You can then still recreate everything, but it's a pain.
But as I said, generally they're just providing the drive as is in which case there won't be any issue.
