Seagate IronWolf 12TB HDD Review

IOMeter 4K Random and 128K Sequential



Moving into IOMeter, I added in RAID 0 results for the 12TB IronWolf. RAID was controlled by the Onboard Intel Z370 chipset and RST.




Starting off with random read, we see incremental performance improvements with the new 12TB capacity. This is seen more at higher QD with the 12TB peaking at 700 IOPs, 100 IOPs more than the 10TB. The 12TB RAID array reached a peak of 975 IOPs at QD32.




Write results were much more interesting with the 12TB starting and ending at 700 IOPs again 100 IOPs over the 10TB model. The RAID array on the other hand topped 1400 IOPs start to finish.





Sequential read testing peaked out at 250 MB/s for the 12TB model, 50 MB/s quicker than the 10TB. The RAID array reached 500 MB/s QD4 through QD32.




Write performance again was similar with the 12TB maintaining 250 MB/s QD1 through 32 while the RAID array seemed to hover between 475 and 500 MB/s.
