Learn about the AA and E8 attributes of SMART.

Here is how to use the Solidigm™ Storage Tool to view SMART.


  • The attributes AA and E8 report the "Available Reserve Space", which is the number of reserve blocks remaining.
  • The normalized value begins at 100, which corresponds to 100% availability of the reserved space, and decreases with use.
    • By itself, is not an indicator of a drive problem, as it's expected to decrease.
  • The threshold value for this attribute is 10% availability, at which point the SSD will go into a Read-Only mode, to protect your data and give you time to back up your data.
