Assuming a conventional desktop environment with no extremes or events, 
agreed.  But, I would still test the power supply, test the memory, run 
a long SMART test, and post the complete SMART report.  If the SMART 
overall-health self-assessment test result says "FAIL", then recycle the 
drive.  But if the result is "PASSED", then I would consider keeping it. 
 In any case, I would get more drives and set up RAID.
