I can't wait for datacenters to decommission these so I can actually afford an array of them on the second-hand market.

Home Petabyte Project here I come (in like 3-5 years π )
Exactly, my nas is currently made up of decommissioned 18tb exos. Great deal and I can usually still get them rmaβd the handful of times they fail
Where is a good place to search for decommissioned ones?
Serverpartdeals has done me well, drives often come new enough that they still have a decent amount of manufacturers warranty remaining (exos is 5yr) and depending on the drive you buy from them spd will rma a drive for 5 years from purchase (but not always, depends on the listing, read the fine print).
I have gotten 2 bad drives from them out of 18 over 5 years or so. Both bad drives were found almost immediately with basic maintenance steps prior to adding to the array (zeroing out the drives, badblocks) and both were rmaβd by seagate within 3-5 days because they were still within the mfr warranty.
If youβre running a gigantic raid array like me (288tb and counting!) it would be wise to recognize that rotational hard drives are doomed and you need a robust backup solution that can handle gigantic amounts of data long term. I have a tape drive for that because I got it cheap at an electronics recycler sold as not working (thankfully it was an easy fix) but this is typically a super expensive route. If you only have like 20tb then you can look into stuff like cloud services, bluray, redundant hard drive, etc. or do like I did in the beginning and just accept that your pirated anime collection might go poof one day lol
What kind of tape drive are you using? My array isn't as large as yours (120tb physical), but it's big enough that my only real options for backup are tape or a whole secondary array for just backup.
Based on what I've seen, my options are a prohibitively large number tapes with an older LTO standard or prohibitively expensive tapes with a newer LTO standard.
My current backup strategy consists of automated backups to Backblaze B2 for the really important stuff like personal documents or projects and hoping my ZFS array doesn't fail for everything else.

30/32 = 0.938
Thatβs less than a single terabyte. I have a microSD card bigger than that!
;)
Can't even put it into simplest form.

Lmao the HDD in the first machine I built in the mid 90s was 1.2GB
My dad had a 286 with a 40MB hard drive in it. When it spun up it sounded like a plane taking off. A few years later he had a 486 and got a 2gb Seagate hard drive. It was an unimaginable amount of space at the time.
The computer industry in the 90s (and presumably the 80s, I just don't remember it) we're wild. Hardware would be completely obsolete every other year.
It really was doubling in speed about every 18 months.
My 286er had 2MB RAM and no hard drive, just two 5.25" floppy drives. One to boot the OS from, the other for storage and software.
I upgrade it to 4 MB RAM and bought a 20 MB hard drive, moved EVERY piece of software I had onto it, and it was like 20% full. I sincerely thought that should last forever.
Today I casually send my wife a 10 sec video from the supermarket to choose which yoghurt she wants and that takes up about 25 MB.

Back then that was very impressive!
Yup. My grandpa had 10 MB in his DOS machine back then.

Avoid these like the plague. I made the mistake of buying 2 16 TB Exos drives a couple years ago and have had to RMA them 3 times already.
Their 3tb and 16 TB are super trash. I'm running 20tb and 24tb and they've been solid... So far
I stopped buying seagates when I had 4 of their 2TB barracuda drives die within 6 months... constantly was RMAing them. Finally got pissed and sold them and bought WD reds, still got 2 of the reds in my Nas Playing hot backups with nearly 8 years of power time.
They seem to be real hit or miss. I also have 2 6TB barracudas that have 70,000 power on hours (8 yrs) that are still going fine.
Nice, I agree, I'm sure there is an opposite of me, telling their story of a bunch of failed WD drives and having swore them off.

I mean, cool and all, but call me when sata or m2 ssds are 10TB for $250, then we'll talk.
Not sure whether we'll arrive there the tech is definitely entering the taper-out phase of the sigmoid. Capacity might very well still become cheaper, also 3x cheaper, but don't, in any way, expect them to simultaneously keep up with write performance that ship has long since sailed. The more bits they're trying to squeeze into a single cell the slower it's going to get and the price per cell isn't going to change much, any more, as silicon has hit a price wall, it's been a while since the newest, smallest node was also the cheapest.
OTOH how often do you write a terabyte in one go at full tilt.

My first HDD had a capacity of 42MB. Still a short way to go until factor 10βΆ.
My first HD was a 20mb mfm drive :). Be right back, need some βjust for menβ for my beard (kidding, Iβm proud of it).
So was mine, but the controller thought it was 10mb so had to load a device driver to access the full size.
Was fine until a friend defragged it and the driver moved out of the first 10mb. Thereafter had to keep a 360kb 5ΒΌ" drive to boot from.
That was in an XT.

This is for cold and archival storage right?
I couldn't imagine seek times on any disk that large. Or rebuild times....yikes.
up your block size bro πͺ get them plates stacking 128KB+ a write and watch your throughput gains max out ποΈ all the ladies will be likeπββοΈ. Especially if you get those reps sequentially it's like hitting the juice π for your transfer speeds.

Definitely not for either of those. Can get way better density from magnetic tape.
They say they got the increased capacity by increasing storage density, so the head shouldn't have to move much further to read data.
You'll get further putting a cache drive in front of your HDD regardless, so it's vaguely moot.

These things are unreliable, I had 3 seagate HDDs in a row fail on me. Never had an issue with SSDs and never looked back.
