Acording to this, all drives are bad, but only sda behaves badly. Three more
values are reported as Pre-fail: Spin_Up_Time, Seek_Error_Rate and
Spin_Retry_Count. Full output for sda:

According to the above, I would say only sda and sdb are bad, sda
being the worst of the two. I stand to be corrected as always.
Yeah - that's what it looks like to me as well (having gotten back to a screen other than my smartphone). 

It also looks like those drives are pretty old:
