The drives passes all SMART checks and has nothing flagging as a warning or fault, yet when I do a read test, I get all the errors.

It has seemingly gone away now I have swapped the SATA cable (connector P3) on my LSI card. Is this typical for a faulty connection?
Personally over the last 10 years I've had more sata cables fail on me than drives in my array. (Not counting mobile hard drives or laptop hard drives). If the error goes away you're probably fine.
HOWEVER - I notice you don't have a parity drive. This should be a warning and a giant red indicator that you need to add parity. That'll save you if you have a drive fail out.
Usually a bad cable or connection will give you CRC errors, check your disks attributes and make sure there are no uncorrectable errors.
