  1. Tests done on a Banana Pi using an "APPLE HDD HTS727550A9E362" (Hitachi
  2. 2.5" 500 GB) with kernel 4.1.2 and btrfs' defaults and disabled ASM1051
  3. blacklisting (please keep that in mind since normally UAS will be
  4. automatically disabled for ASM1051/ASM1053 devices and a fallback to BOT
  5. will happen). The following iozone settings were used (4 GB test size to
  6. ensure that disks and not buffers/caches were tested. Only for the IOPS
  7. tests I used 2 GB since otherwise it would've took ages and the results
  8. didn't vary between 2 and 4 GB):
  9.  
  10. iozone -a -g 4000m -s 4000m -i 0 -i 1 -r 4K
  11. iozone -a -g 4000m -s 4000m -i 0 -i 1 -r 1024K
  12. iozone -O -i 0 -i 1 -i 2 -e -+n -r 4K -s 2000m
  13.  
  14. Cpufreq setting as follows:
  15.  
  16. echo performance >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
  17. echo 960000 >/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
  18.  
  19. (Sidenote: All three controllers support SAT so you can query S.M.A.R.T.
  20. values and trigger selftests: "smartctl -d sat")
