Well, 3.5" SSDs are certainly possible, but 2.5" (or in fact m.2) might just be a better form factor for SSDs. The thing is, an SSD is just a bunch of chips on a PCB, so they really don't need the extra height afforded to them by a 3.5" bay.

You could probably fit 2 pcbs one on top of the other within a 3.5" drive, but that would probably need a third PCB to connect the two which would be more complicated to manufacture and be worse for cooling than using two individual 3.5" or m.2 cards.

Also, for a bunch of reasons smaller is usually better. Generally, it tends to be cheaper to use a few large capacity chips on a small board than it is to use a lot of lower capacity chips on a larger board. Of course fewer parts also means fewer potential points of failure, so better for quality control. And again, smaller cards are better for case airflow and cooling.

I just addressed that in a post above yours.

This new 40TB hard drive from Seagate is just the beginning—50TB is coming fast! - Lemmy.World

Basically, smaller form factors are probably just better in this case. 3.5" drive bays were designed with more complicated mechanical drives in mind, and given how nand flash memory works, they don't make as much sense for SSDs.

Great, can't wait for it to be affordable in 2050.

Is this true? I remember them being very reliable in the past.

"you only"

My recommendation is none of them last forever. Get what is available, decent price and warranty, replace when needed. Drives are consumable.

I mean comparatively to HDDs.

Of course there are also challenges to making a high capacity SSD, but i don't think they are using fundamentally new methods to achieve higher capacities. Yes they need to design better controllers and heat management becomes a larger factor, but the nand chips to my knowledge are still the same you'd see in smaller capacities. And the form factor has the space to accomodate them.

If HDDs could just continue to stack more of the same platters into a drive to increase capacity they'd have a much easier time to scale.

Oh yeah, I run spinning rust in my nas. All data storage for me is on HDDs, only OS date is on the SSD. That's for the nas and my computer.

I can't wait to upgrade my NAS to a 200Tb Setup

Yeah Exos are enterprise drives, so there's no point in making them quiet like they do with lower speed desktop stuff.

I think people say this because there was one specific 6TB model that does really poorly in BackBlaze reports, combined with a generally poor understanding of statistics ("I bought a Seagate and it failed but I've never had a WD fail").

I will also point out that BackBlaze themselves consistently say that Seagate and WD are pretty much the same (apart from the one model), in those exact same reports

When setting up RAID1 instead of RAID5 means an extra few thousand dollars of cost, RAID5 is fine thank you very much. Also SSDs in the size many people need are not cheap, and not even a thing at a consumer level.

5x10TB WD Reds here. SSD isn’t an option, neither is RAID1. My ISP is going to hate me for the next few months after I set up backblaze haha

But have you had to deal with the rebuild of one of those when a drive fails? It sucks waiting for a really long time wondering if another drive is going to fail causing complete data loss.

Not a 10TB one yet, thankfully, but did a 4TB in my old NAS recently after it started giving warnings. It was a few days iirc. Not ideal but better than the thousands of dollars it would cost to go to RAID1. I’d love RAID1, but until we get 50TB consumer drives for < $1k it’s not happening.

I can't wait to lose even more data when this thing bricks

Your own lil cloud

They're called Seagate, not Landgate.

I'm still waiting for prices to fall below 10 € per TB. Lost a 4 TB drive prematurely in the 2010s. I thought I could just wait a bit until 8 TB drives cost the same. You know, the same kind of price drops HDDs have always had about every 2 years or so. Then a flood or an earthquake or both happened and destroyed some factories and prices shot up and never recovered.

I know people love to dunk on Seagate drives, but it was really just the one gen that was the cause of that bad rep. Before that the most hated drives were the "deathstars" (Deskstars). I have a 1TB Seagate drive that is 10 years old and still in use daily. Just do some research on which drive to buy, no OEM is sacrosanct. I'd personally wait 6 months to a year before buying one of these drives though, so enough people have time to find out if this generation is trouble or not.

Heh. In my case, one WD SSD failed miserably on me.

Thanks for the explanation.
