while I have done my fair share of research in the last couple of years, I still haven't decided if it's wise to use one of these giant hard drives as a backup for my secondary backups of my old family photos, videos and other junk. (currently around 15TB of stuff... they are currently on the original media, two 10TB hard drives, on the cloud(both Google Drive and iCloud), as well as data Blu-ray discs.

My thinking is that I can NEVER have enough back-ups.(of back-ups of back-ups) because any one of them can and probably will fail several years down the road?

When big SSDs4TB or 8GB+ are cheap enough, I may also look into getting some of those as another form of back up?

Sound paranoid... well... yes... becuase while I was backing up stuff, two of my back-up drives died within a day of each other, (one WD and one Seagate) and I lost all of my converted film and photos between 1980 and 1985.

That's why everythying that I have currently has at least 3 different forms of back-ups on different medias or the cloud, at a minimum, and stored at different locations(my house or with my other family members)

By way of comparison of recent sales on external 20 TB drives, the WD Easystore was $250 on Black Friday and the WD Elements was $266 on Prime Day in the Fall.

I just bought four of these today and so far I've shucked one. It's branded as a Baracuda and uses HAMR.

Update: All four drives are the same.

People need to get over the Seagate 1.5tb fiasco. Jesus christ it's been how long now.

And wasn't there a patch to fix that model or was it the 2tb?

That's a risk with the latest revelation, but it's not an official Barracuda and may be a HAMR drive. Hope I got an older drive from BB then, but not the end of the world if it's newer and Barracuda. It's not a drive I will keep running.

How do we feel about HAMR?

Thanks much! How are they performance wise? Are you getting top SATA transfer speeds for large files at least?

I'm using a Nuc12Pro and a USB 3.1 Gen 2 8 bay DAS enclosure which limits me to 10gbps. I have 4 recertified 12TB Exos x24 and 4 shucked 20TB drives. I both sets of drives in storage spaces with simple resilency and 4 columns. Crystal Disk Mark had them both in the 900 MB/sec range for sustained read and writes. CDM did report the 4k random write performance on the 20TB drives was substantially slower then the Exos drives. But I'm not paying any attention to it since it doesn't matter for my use case. If I cared about IOPs I'd move the data to NVME.

How often do you refresh the backup of your offsite HDDs? I'm thinking of doing this myself.

Not the person you posted to, but I have a trunas box with a raidz2 (essentially a raid 6, so two drives can fail but more space and head read speed). I have an attached external I use sync to just copy files over nightly. Every 3-6 months I will pull the attached external drive and put on a different one. I want to either do a fireproof safe or just mail it to someone for external but I've been lazy. But I have 4 drives of redundancy overall before I'll lose everything.
I blame these deals every few years for a couple more TBs. I add a couple TB of data and these jerks release another drive and a sale of 30% off and now I have a shitton of under 5tb drives. I also don't need more space. I also hate selling them because I hate dealing with people. Hoard like a dragon.

Has anyone purchased one of these very recently and shucked it? Any idea what drive is inside?

I saw one Amazon review on the 20TB from December 2, who shucked it and it was an Ironwolf Pro ST20000NE000

When Best Buy sells it for $230, everyone else likely has the same price. In particular Amazon, where you can get 5% cash back.

Amazon is only offering this one from a less-than-ideal seller. You'll still get 5% and are safest on returns as long as you choose "Other Sellers" and make sure Amazon is the shipper.

Thanks for Sharing
Interesting, The search with model # ST20000DM001 isn't fetching much information.Couldnt even find anything on Seagate.com Were you able to check the other drives. may be not by shucking them all, but checking them through Crystaldisk info should get you the model numbers for the remaining drives. BTW, Where did you get them?

With the caching implemented in many modern drives, the fact that CrystalDiskMark reports peak values renders it of questionable value. Case in point, the Exos drives can rapidly cache about 3-5 seconds worth of 4K random writes, before dropping down to the same speed as an IronWolf Pro.

I could be wrong but I thought it was the 3TB that was a disaster. Also, I read it was related to a faulty parking ramp.

Boomer meme from 2001 when seagate made horrible deskstar (deathstar) drives that failed at an abnormally high rate.

Today they make the most reliable drives.

Seagate didn't make Desktar drives, that was IBM / Hitachi

Gen X and Millennials actually grew up with Seagate shit-era drives, not boomers. If you are a Gen X or Millennial, chances are, if you had any experience with Seagate drives up until the turnaround, it was bad, really bad. Hence the reputation.

For those who plan to shuck the drive to use in the NAS, please be aware that it has a Barracuda inside (ST20000DM001) not Exos or Ironwolf Pro. It uses HAMR instead of CMR.

In for 2; this is a great price and when combined with the $10 Coupon a steal that meets Black Friday Price per TB that Walmart had on Black Friday for the 14TB version.

Would there be any difference using HAMR Vs CMR in NAS devices. Or any other significant Pros/Cons over the other (even for non-NAS usage)?

Since HAMR uses laser to heat up the area that need write, so it has slower random write speed. Plus the concern is that with constant random writes the disc would degrade over the time.
However most external storage are used to "write once, read many" so this is unlikely to affect most people.
