Depends...
our internal statistics on older boxes:
- 73 drives 6717 (!) on old boxes - no failure in the last 12 months
- 168 drives 6718 on old boxes - 1 failure in the last 12 months
- 40 drives 6719 on old boxes - 8 failures in the last 12 months
- 180 drives 4326 on aged boxes - 1 failure in the last 12 months
- 168 drives 4327 on i5 boxes - 9 failures in the last 12 months
- 84 drives 4328 on i5 boxes - 3 failures in the last 12 months
drives in Power6 boxes and newer: <1% of failing drives in 12 months.
Nothing to worry about.
The old 6717 are rock-solid unless you power them down. And yes - we run a lot of old customer boxes for archive purposes. Old software forces them to :-)

Age. Your mean time between failure date on those drives has long since passed.
