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’ve personally just bought what is cheaper $/Gb if they’re broadly equal then features & power, if still locked I have tended towards WD. But I’m not storing anything critical and if a drive failed, I’d be annoyed but that’s about it.

    I always run WD. None of my drives have failed in regular use. Been using WD in my NAS for two years now without issues.

    According to the detailed information that back blaze releases on drive reliability and pricing. Western digitals cost more and are more reliable if you’re keeping the drives for a very long time. If you’re replacing the drives in two to three years with something else go Seagate as Seagate drives fail more often at the 3 to 4 years I think. It’s been a long time since I read the review but if you do a custom Nas with disc shelves. It’s even cheaper if you get a bunch of used Enterprise drives yes they’re going to have a ridiculous amount of hours on them but you put them into a raid 2 or a raid 3 and you pay a little bit more monitoring attention to them but you’ll save a couple extra dollars on those much larger arrays my two cents from what I I’ve read.

    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.

    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.

    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

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

    Seagate has permanently lost my business since their 50% failure rates from many years ago. It’s well documented if you search for it. Never again. Lost multiple arrays because of this.

    Looking purely at your specs posted, I’d probably lean towards WD, mainly because it has a higher cache.

    In terms of experience, I have an Ironwolf Pro 18TB, and some WD 20TB Red Pros.

    The Ironwolf is noticeably louder than the other drives and often/frequently does a sound as if there’s heavy activity on the disk.

    This is something to consider if you will have these drives in the same room as you.

    I usually just buy the cheapest TB/EUR that i can get new and verify that they are not drastically worse in terms of power use compared to the next cheapest option.

    So in your case i would go with the Exos.
