Seagate Ironwolf 8 TB questions

[Krzaku]

I just bought a couple of those to add to my array. They seem to be working fine however I just noticed that the Load Cycle Count is pretty high, over 400 in 1 week of usage. This is almost 8x higher than my Ironwolf 3 TB drives did in almost a year of usage. They supposedly are rated for LCC values of 600000 but it still is disconcerting. I have disabled drive spin-down however I also noticed that the 8 TB drive does not support APM (nothing comes up in hdparm) while the 3 TB does so I'm not entirely sure if it respects this setting (the indicator light on the WebUI is always green though). I also have very high G-Sense Error Rates (2000-3000) however this seem to be a very common issue and does not SEEM to affect anything. All this makes me wonder if this isn't just another flop like the old ST3000DM001 were. Does anyone use these drive and can share what their smart values are?

LCC is the head locking mechanism. Some drives are more aggressive than others. WD is historically the worst. 400 a week honestly would not bother me too much. I am used to seeing them in the tens of thousands. At this rate you'd hit 50,000.on about 2.5 years, and 600,000 in 30 years. I've seen.WD drives over a million in only a few years. And I've never seen a drive die of excessive LCCs.
