Is surface scan analysis necessary on SSDs?

[WFHC-WI]

Hi all,

I'm having some difficulty finding info about whether surface scans are useful, harmful, or neither on a logical array (RAID 1) composed of solid state drives.

On one hand, SSDs are incredibly less likely than traditional disks to suffer from physical corruption. Also, doesn't a scan create unnecessary activity on the disk and cut into the limited number of writes it can tolerate?

On the other hand, from within version 8.70.9.0 of the Array Configuration Utility HP says (without specific reference to SSDs):

"Disabling Surface Scan Analysis is not recommended as it will prevent the controller from proactively finding and correcting disk surface errors, which may lead to data loss."

So what does conventional wisdom have to say about scans on SSDs? Thanks in advance for your answers and opinions...
