These are not shitty shingle SMR drives. SMR write speed is less than 80 MB/s. People are reporting 200 MB/s for these seagate drives.

I bought two last time this was on sale and shucked them into my nas. I ran a stress test and secure wiped them followed by a extended smart test, both ran it fine without issues. Temps were good for me, lower than my wd reds

That's literally EVERY thread on SD. Most of the content is just two factions trying to prove the other is wrong. If you don't believe me, head on over to the recent lululemon jogger thread, same thing, different product.

Anyway, that's why using a strong sense of filtration and due diligence helps with these comments. Once in a while you get a good nugget of info/wisdom which makes it worth the effort if you actually need said item.

You can expect those transfer rates on a brand new / clean SMR drive. The issue is that SMR drives slow down dramatically when you are re-writing data (e.g. random writes on the drive as opposed to sequential writes to unused space on the drive).

SMR drives have their place, and that's for write-once, read-many type applications (such as persistent backups).

For me its backup of files for cold storage in a safe when full.

Since mine is full, I'll try to remember to pull it out of the safe and try overwriting some of the files and see what happens.

Don't mix temp units. It is very hard for us to read

I'm used to reading computer component temps in C but my home thermostat is in F. I don't make the rules! I had to google it, but 72F is around 22C.

Can you please provide evidence of your statement that it is an SMR drive inside?

No, he can't. He is in another recent thread (24TB Seagate drive) spouting all sorts of contradictory claims and nonsense. In that one he claimed data centers had been using HAMR drives for a long time and proven that HAMR is a tried and tested technology. Now he's in this thread stating that data centers are now starting to adopt them. Some sort of weird agenda he has. In that other thread he mentioned he runs 1PiB so he knows what he is talking about, and repeated this about 4 times...cringe. Take his comments with a grain of salt.

Quote from CTRFK8

HAMR was protyped shown 20 years ago at CES and was invented theorized in 1953. seagate owns the patent and WD will be moving to this tech as well . also a form of HAMR tech has been used in exo drives from the x14 to current x24. there are plenty of articles out there showing the pipeline and production , again this is a SMR drives not CMR and is not made for RAID . It is not enterprise grade and not recommended. SMR is for cold storage backups, you stick it in a closet after writing to it. very sneaky for seagate to do this to consumers .

Still no proof on the Barracuda being SMR huh?
Plenty of articles? Nope. You mean expected timeframes and roadmaps which had many delays and is only now beginning to roll out the promised HAMR technology.

https://d18rn0p25nwr6d.cloudfront...a91d09.pdf

This is Seagate's official report on rolling out HAMR to other drives at volume scale. The whole claim that they've been in use since 14TB is on a timeline not anything official. Now as far as this poster's claim of it being old and highly tested technology, this is what the report states:
"Seagate has successfully completed qualification testing for its HAMR based Mozaic drives with several customers within the Mass Capacity markets, including a leading cloud service provider. The Company expects to begin shipping initial HAMR product volume to this cloud customer in the coming weeks"
So they did a pilot run, yet we have this random person touting it as a technology that is fully vetted. Date of report? December 3, 2024.

Again, take this person's comments with a grain of salt. Especially given they feel they need to reply in 5 different comments at a time. HAMR is not fully tested, and again this person has yet to provide any substantial proof that the drive they supposedly had was SMR. Bit of a joker really.

P.S. Here is Seagate's datasheet on what technologies are in which drives. Note how neither the EXOS E nor EXOS X drives are listed as containing HAMR under 24TB. So much for that claim that they've been in use since the x14.

You can't even. Quote correctly who would listen to you

Not even sure what you were trying to say here. Read my edit, x14s never contained HAMR as your supposed claim states. What agenda do you have in trying to bs so much here?

I can also take a photo and upload it if needed. it's a crap smr barracuda best buy bought huge lots of these at a cheap price through seagate. hence why the huge price decrease. The 22 and 24 TB thankfully are CMR still or maybe you get old stock 20TB and get the exo x20 which is CMR.

So… do it. Share that photo. Write your username on a slip of paper, take the picture and share it. Otherwise, gtfo.

^This. I currently manage hundreds of TB of data in a data center that runs exclusively on Seagate EXOS SAS drives. In five years of continuous writes, we've had ZERO drive failures. Clearly EXOS drives aren't terrible based on real-world experience. I've managed literally thousands of spindles over my IT career - SATA, SAS, FC, you name it. Everything from NetApp Filers, 3PAR, EMC VNX to HP Nimble and Dell Compellent. Guess which brands I've seen fail? All of them. Compare this experience with your average consumer fanboy that may have used two dozen drives in his whole life telling you Seagate EXOS is garbage. Bring some real data before you trash something with a dataset of n=5. For the record, I also manage a fleet of Synology NASes at client locations with over 200 drives spinning in production for years at a time, while heavily write biased (hourly backups, 24x7x365). ALL are WD Reds, which are also just fine.

Thanks for your real world experience. I worked in IT before the days of data centers and NAS units. Our biggest concern was whether to go with clones for the two big platforms of our time. Drives back then were under 80 MB and when the drives parked its head you heard it if you were anywhere within the room. The days of MFM and IDE drives warmed the room too.
Bought some used seagate drives off ebay that were taken out of data centers at year 4 for my ugreen NAS. Running for 5 months with no problems.
