Life time is always a statistical statement and therefore I consider it
very unlikely that two or more of them fail at the same time - perhaps 
with one (big) exception. A given brand/model might be very sensitive 
to power failures or excess voltages, and in that case many of them 
could fail after a power failure - or excess voltage.

Since my data is not rapidly changing, I backup my data several times a 
day onto a spare disk which I spin down in between (using hdparm).
At least I hope to increase the life time of that backup disk this way.
