With an SSD, though, once one drive goes there's a decent (perhaps small, but far from negligible) chance that a second drive will go out before you've had a chance to replace the first one. Which makes things complicated, but is much better than the similarly likely scenario that a second SSD fails shortly after you replace the first one. Because then it's possibly happening during the rebuild, and if that happens then it really will bring down the whole RAID array.
Not disputed that there's a slightly increased chance of concurrent disk failures with SSD, but on what basis is a second failure before rebuild any better than aduring it?
Also, I'm guessing you're referring to RAID5, as RAID6 / RAID DP is immune to double-disk failure, and RAID 10 and 0+1 are more tolerant of it.
