Wanted to make sure I described the situation correctly.

I have Windows installed on a single Hard Drive computer with RAID selected (don't ask me why that's how I received it)

I have a Kingston SSD. 

ePSA passes.

Dell Diagnostics Long Test gives a "S.M.A.R.T. Wear Level use warning" on the SSD

Kingston's diagnostics software reports no errors on both short and extended S.M.A.R.T tests.

I don't see anything wrong with the laptop, except I have now started imagining sometimes Windows is slow to boot up. Otherwise laptop runs great.

So how can I reliably discover if my SSD is dying or not given two conflicting reports? Should I trust Dell's Diagnostics over the manufacturer (Kingston)?
