Hybrid Information Read-Write Test (LOGO)

  • Article

This test validates the behavior of reads and writes to the drive with priority. There are several test cases that the drive must pass:

  • Being able to read and write to each priority for most of the priority

  • Ensuring that the optimal write granularity is being properly reported in the hybrid log

  • Ensuring that priority updates are updated

  • Ensuring that the replacement policy in the cache is sensible
