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).

Not to start a flame war

says the guy lighting a cigar at the oil refinery..... :)

in all seriousness, look at used HGST (western digital) drives many times you can find good deals on drives that where hotspares most of their life at almost 1/2 msrp. if you need new drives stay with the enterprise variants.

I have not heard good things about recent seagate consumer drives.

WD/HGST gold drives have been rock solid at work. (wd purchased HGST and the 'helium' line up is almost all just rebranded HGST.)

also, don't count out toshiba drives. they are a 'smaller' company in the us/europe but they make decent drives in my experience.
