it's was also the case with SAS drive ! :)

We buy 3 years ago at the same time some sas drive to put them in raid
(seagate SAS 15k) and 2 of them crash at the same time (24h between the
2 crash)
... this because the sas was coming from the same "lot" ... raid 5 can
survive to one disk crash and we was thinging that the probability of 2
simultaneous hard drive crash was near impossible ... it's was not !
