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).

Off topic but, 20TB is amazing to see. When I got my first PC in 1995, 2GB was the biggest you could get. Then I got another in 1998 and I had a 16.8GB hard drive and it wasn't standard in PC's for over a year. 25 years later and we're up to 20TB drives. It also costs about the same as the 16.8 not adjusting for inflation.
