I forgot to mention that with an SSD it's important to watch the
remaining lifetime. These values can be read with smartctl. When putting
the disk behind a hardware raid controller, you might not be able to
read them from the OS, and the hardware RAID firmware might be to old to
not know about the SSD lifetime indicator or not even show it.
