Most SSDs reviews focus their attention on speed and endurance (terabytes written) benchmarks.  

However, searching a little bit more on the subject, I've found the following issues:

Therefore, in **summary**:

* SSDs experience significantly higher catastrophic failure ratios due to power loss than do HDDs (ex: bricked device, metadata corruption, uncorrectable errors, ...).
* SSDs, including enterprise SSDs, should not be trusted to be as robust as HDDs.

### Questions

1. Is my summary correct?
2. Are desktop users really experiencing higher failure rates with SSDs than with HDDs?
3. Should desktop users indeed be worried about bricked SSDs due to power loss?
