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).

    Can’t help with these 3 specifically. I ordered som wd gokd drives. Which are the ones intended for datacenters. Price was lower. And I think it was 10^16 not 10^15. That may not sound like alot. But doing the math, number of bits on a raid6 of 8 14tb drives, basically going to hit 10^15. And they supposedly have firmware to handle vibration. Maybe worth looking into.

    As for these 3, I would think they would all be fine choices.

    Had a lot of wd fail over the years. Since upgrading to Seagate exos only. Haven’t had any failures. Maybe due to the fact they are enterprise drives. Not sure. But very happy with Seagate exos

    Wd gold. They’re Hitachi, and those drives were epic. If I go hdd again, those are what I’ll use. I have an array of 4 Hitachi nas drives now, but they’re 3tb.

    Anecdotally out of the maybe 100 drives I have dotted around here the failed ones are mainly Seagate.

    In the field though, makes no odds. Most of the kit I am supplied with comes with Seagate, not had any issues with them.

    Exos are noisy, but they work great…

    And the helium fill? Makes them sound funny
