Not to start a flame war, but WD or Seagate for 20TB drives? (no shucking) (alien.top)

I have a Synology that needs more storage. Thoughts on WD vs Seagate?

I've always bought WD Red, but with the recent WD controversies (including the SMR/CMR scandal and the recent WDDA warning), I'm considering Seagate. Also, I can't find any difference between the IronWolf Pro and Exos drives. What am I missing?

Metric	Seagate IronWolf Pro 20TB	Seagate Exos X20 20TB	WD Red Pro 20TB
Spindle speed (RPM)	7200	7200	7200
Internal transfer rate	285 MB/s	272 MB/s	268 MB/s
Gas	Helium	Helium	???
Cache	256MB	256MB	512MB
CMR?	Yes	Yes	Yes
MTBF (hours)	2.5m	2.5m	2.5m
Non-recoverable errors per bits read	1 in 10^15	1 in 10^15	1 in 10^15
Load unload cycles	600k	600k	600k
Workload rate (TB/yr)	550	550	550
Annualized Failure Rate (AFR)	0.35%	0.35%	???
Warranty	5yr	5yr	5yr
Price	$349.99	$329.99	$379.99

Also, please don't recommend shucking (those drives are in external enclosures because they didn't pass QC to become internal HDDs).

Seagate for internal drives, WD for external.

You seem to be in the minority in regards to seagate, any particular reason you prefer them for internal drives?
