  10. ## If unset systemwide smartctl is used if found.
  11. SMARTCTL="./smartctl"
  13. ## Path to logfile. Leave empty or comment out to disable logging.
  14. LOGFILE="./ssdlog.csv"
  16. ## Unit used for logging of read/written data.
  17. ## Possible values: B, KB, MB, GB, KiB, MiB, GiB, b, Kb, Mb, Gb, Kib, Mib, Gib
  18. ## Small "b" refers to bit, capital "B" to Byte.
  19. ## Units with an "i" are binary based (1 KiB = 1024 Byte)
  20. ## whereas units without are decimal based (1 KB = 1000 Byte)
  21. LOG_SIZE_UNIT="MiB"
  23. ## Number of decimals used for logging of read/written data.
