Here is the last two paragraph jac mentions:
Makes sense to me and I would say that SSDs are very reliable. I especially like Intel SSDs. I've sold quite a few of them and none has been returned for RMA
SSDs are known for their reliability and performance. The LSI SSD Guard technology, that is unique to MegaRAID controllers, increases the reliability of SSDs by automatically copying data from a drive with potential to fail to a designated hot spare or newly inserted drive. A predictive failure event notification, or S.M.A.R.T command, automatically initiates this rebuild to preserve the data on an SSD whose health or performance
falls below par. If a hot spare is not present or not assigned, MegaRAID Storage Manager (MSM) will recommend that the user insert a hot spare
drive into an available slot.
Because SSDs are very reliable, non-redundant RAID 0 configurations are much more common than in the past. SSD Guard technology offers
added data protection for RAID 0 configurations by actively monitoring the status of the SSDs. SSD Guard, together with MegaRAID FastPath
software, allows users to take full advantage of the reliability and performance attributes of SSDs.
