Great, can’t wait to afford one in 2050.
That’s good, really good news, to see that HDDs are still being manufactured and being thought of. Because I’m having a serious problem trying to find a new 2.5" HDD for my old laptop here in Brazil. I can quickly find SSDs across the Brazilian online marketplaces, and they’re not much expensive, but I’m intending on purchasing a mechanical one because SSDs won’t hold data for much longer compared to HDDs, but there are so few HDD for sale, and those I could find aren’t brand-new.
SSDs won’t hold data for much longer compared to HDDs
Realistically this is not a good reason to select SSD over HDD. If your data is important it’s being backed up (and if it’s not backed up it’s not important. Yada yada 3.2.1 backups and all. I’ll happily give real backup advise if you need it)
In my anecdotal experience across both my family’s various computers and computers I’ve seen bite the dust at work, I’ve not observed any longevity difference between HDDs and SSDs (in fact I’ve only seen 2 fail and those were front desk PCs that were effectively always on 24/7 with heavy use during all lobby hours, and that was after multiple years of that usecase) and I’ve never observed bit rot in the real world on anything other than crappy flashdrives and SD cards (literally the lowest quality flash you can get)
Honestly best way to look at it is to select based on your usecase. Always have your boot device be an SSD, and if you don’t need more storage on that computer than you feel like buying an SSD to match, don’t even worry about a HDD for that device. HDDs have one usecase only these days: bulk storage for comparatively low cost per GB
I replaced my laptop’s DVD drive with a HDD caddy adapter, so it supports two drives instead of just one. Then, I installed a 120G SSD alongside with a 500G HDD, with the HDD being connected through the caddy adapter. The entire Linux installation on this laptop was done in 2019 and, since then, I never reinstalled nor replaced the drives.
But sometimes I hear what seems to be a “coil whine” (a short high pitched sound) coming from where the SSD is, so I guess that its end is near. I have another SSD (240G) I bought a few years ago, waiting to be installed but I’m waiting to get another HDD (1TB or 2TB) in order to make another installation, because the HDD was reused from another laptop I had (therefore, it’s really old by now, although I had no I/O errors nor “coil whinings” yet).
Back when I installed the current Linux, I mistakenly placed
/varand/home(and consequently,/home/me/.cacheand/home/me/.config, both folders of which have high write rates because I use KDE Plasma) on the SSD. As the years passed by, I realized it was a mistake but I never had the courage to relocate things, so I did some “creative solutions” (“gambiarra”) such as creating a symlinked folder for.cacheand.config, pointing them to another folder within the HDD.As for backup, while I have three old spare HDDs holding the same old data (so it’s a redundant backup), there are so many (hundreds of GBs) new things I both produced and downloaded that I’d need lots of room to better organize all the files, finding out what is not needed anymore and renewing my backups. That’s why I was looking for either 1TB or 2TB HDDs, as brand-new as possible (also, I’m intending to tinker more with things such as data science after a fresh new installation of Linux). It’s not a thing that I’m really in a hurry to do, though.
Edit: and those old spare HDDs are 3.5" so they wouldn’t fit the laptop.
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.
Lmao the HDD in the first machine I built in the mid 90s was 1.2GB
Back then that was very impressive!
Yup. My grandpa had 10 MB in his DOS machine back then.
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.
I had 128KB of RAM and I loaded my games from tape. And most of those only used 48KB of it.
Yeah we still had an old 8086 with tape drive and all from my dad’s university times around, but I never acutely used that one.
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.
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.
I recently had to send back a Barracuda drive as well. I’m seeing if the Ironwolf drive fares any better.
I have heard good things about their ironwolf drives, but that’s a enterprise solution drive, so hopefully it’s worth it
I have several WDs with almost 15 years of power on time, not a single failure. Whereas my work bought a bunch of Seagates and our cluster was basically halved after less than 2 years. I have no idea how Seagate can suck so much.
About 10 years ago now, at a past employer, had a NAS setup that housed a bunch of medical data…all seagate drives. During my xmas PTO…I was lead on DR…yea fuckers all started failing one after another. Took out 14 drives before the storage team said fuck this pulled it offline and had a new NAS brought in from EMC, was a fun xmas restoring all that shit. Seagate used to be my go to, but it seems like every single interaction I have with them ends in disaster.
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.
Seagate in general are unreliable in my own anecdotal experience. Every Seagate I’ve owned has died in less than five years. I couldn’t give you an estimate on the average failure age of my WD drives because it never happened before they were retired due to obsolescence. It was over a decade regularly though.
well until you need capacity why not use an SSD. It’s basically mandatory for the operating system drive too
It never ceases to amaze me how far we can still take a piece of technology that was invented in the 50s.
That’s like developing punch cards to the point where the holes are microscopic and can also store terabytes of data. It’s almost Steampunk-y.
That’s how most technology is:
- combustion engines - early 1900s, earlier if you count steam engines
- missiles - 13th century China, gunpowder was much earlier
- wind energy - windmills appeared in the 9th century, potentially as early as the 4th
Almost everything we have today is due to incremental improvements from something much older.
Solid state is kinda like a microscopic punch card.
More like microscopic fidget bubble poppers.
When the computer wants a bit to be a 1, it pops it down. When it wants it to be a 0, it pops it up.
If it were like a punch card, it couldn’t be rewritten as writing to it would permanently damage the disc. A CD-RW is basically a microscopic punch card though, because the laser actually burns away material to write the data to the CD.
They work through electron tunneling through a semiconductor, so something does go through them like an old punch card reader
So are optical discs
Much more so than solid state.
30/32 = 0.938
That’s less than a single terabyte. I have a microSD card bigger than that!
;)
Can’t even put it into simplest form.
Now now, no self-shaming about the size of your card. It’s how you use it!
Some IOT perverts are into microSD
cool never will buy another seagate ever though.
Same but western digital, 13gb that failed and lost all my data 3 time and 3rd time was outside the warranty! I had paid 500$, the most expensive thing I had ever bought until tgat day.
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 😅)
better start preparing with a 10G network!
Exactly, my nas is currently made up of decommissioned 18tb exos. Great deal and I can usually still get them rma’d 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 rma’d by seagate within 3-5 days because they were still within the mfr warranty.
If you’re 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.
eBay sellers that have tons of sales and specialize. You can learn to read between the lines and see that decom goods are what they do.
SaveMyServer is a perfect example. Don’t know if they sell drives though.
Nice, where do you get yours?
also curious, buying new is getting too pricey for me
I personally use goharddrive and serverpartdeals on eBay and have had good luck, but I’m always looking for others
Never used goharddrive but can def endorse spd
radarr goes brrrrrr
sonarr goes brrrrrr…
barrrr?
…dum tss!
My first HDD had a capacity of 42MB. Still a short way to go until factor 10⁶.
My first HD was a 20mb mfm drive :). Be right back, need some “just for men” for my beard (kidding, I’m 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 5¼" drive to boot from.
That was in an XT.
it honestly could have been a 10mb, I don’t even remember. only thing I really do remember is thinking it was interesting how it used the floppy and second cable, and how the sound it made was used in every 90’s and early 2000’s tv and movie show as generic computer noise :)
You have me beat on the XT, mine was a 286, although it did replace an Apple 2e (granted both were aquired several years after they were already considered junk in the 386 era).
I remember the sound. Also, it was on a three wheel table, and the whole thing would shake when defragging.

Oh noooo 😭
The two models, […] each offer a minimum of 3TB per disk
Huh? The hell is this supposed to mean? Are they talking about the internal platters?
More than likely
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 💪 get them plates stacking 128KB+ a write and watch your throughput gains max out 🏋️ all the ladies will be like🙋♀️. Especially if you get those reps sequentially it’s like hitting the juice 💉 for your transfer speeds.
Random access times are probably similar to smaller drives but writing the whole drive is going to be slow
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.
For a full 32GB at the max sustained speed(275MB/s), 32ish hours to transfer a full amount, 36 if you assume 250MB/s the whole run. Probably optimistic. CPU overhead could slow that down in a rebuild. That said in a RAID5 of 5 disks, that is a transfer speed of about 1GB/s if you assume not getting close to the max transfer rate. For a small business or home NAS that would be plenty unless you are running greater than 10GiBit ethernet.
I thought I read somewhere that larger drives had a higher chance of failure. Quick look around and that seems to be untrue relative to newer drives.
One problem is that larger drives take longer to rebuild the RAID array when one drive needs replacing. You’re sitting there for days hoping that no other drive fails while the process goes. Current SATA and SAS standards are as fast as spinning platters could possibly go; making them go even faster won’t help anything.
There was some debate among storage engineers if they even want drives bigger than 20TB. The potential risk of data loss during a rebuild is worth trading off density. That will probably be true until SSDs are closer to the price per TB of spinning platters (not necessarily the same; possibly more like double the price).
If you’re writing 100 MB/s, it’ll still take 300,000 seconds to write 30TB. 300,000 seconds is 5,000 minutes, or 83.3 hours, or about 3.5 days. In some contexts, that can be considered a long time to be exposed to risk of some other hardware failure.
Yep. It’s a little nerve wracking when I replace a RAID drie in our NAS, but I do it before there’s a problem with a drive. I can mount the old one back in, or try another new drive. I’ve only ever had one new DOA, here’s hoping those stay few and far between.
What happened to using different kinds of drives in every mirrored pair? Not best practice any more? I’ve had Seagates fail one after another and the RAID was intact because I paired them with WD.
You can, but you might still be sweating bullets while waiting for the rebuild to finish.
