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).

    I was collecting dead hard drives for the magnets and shit, very few WD drives. Most drives were Seagate. I will never personally buy one again.
