they are far more reliable than normal drives, but you would still want to 
have a mirrored pair for true audit-grade purposes. they do wear out over 
time (although that time is expected to be several years worth of 
continuous write activity)

that being said, for my normal systems I am now buying a single SSD where 
before I purchased a mirrored pair of high-speed SCSI/SAS drives
