You should be able to run the long tests via SMART using the 
smartmontools (smartctl) as well, in FreeBSD. There are a number of 
different tests (see man page) each doing different things -- 
unfortunately, they rarely do the same things on different make/model 
disks as well.

But it is better to test the second disk to check if it has the same 
type of problem.

It is not only possible, it is typical. This is why the recommendation 
to build dependable array is to use disks from different vendors/lots.

It may be the manufacturing lot having undetected defects. It may be 
that during shipping, that group of disks experienced bad handling etc 
-- you may have purchased the disks at different times, yet they may 
come from the same manufacturing lot and shipment.
