these values:

5 Reallocated_Sector_Ct
196 Reallocated_Event_Count
197 Current_Pending_Sector
198 Offline_Uncorrectable

are all zero for both disks, so if these remain zero after a successful 
long test with *no LBA errors* then that would seem to me at least to 
indicate there's no problems with the disks themselves. If, in the face 
of those results, this persisted:

then yeah I'd say bad cable/bad interface
