Reading the daily news article about SSD reliability.
Quote: While this is an important and useful study, for many of us hard drives will remain primary storage for decades to come. While they are a little less reliable, and use more power, their cost per bit can't be beat.
I didn't know HDD were [measured?] less reliable than SSD. Hmmm.
My own machines have pairs of SSD's - one as a mirror (not raid, I do it manual) coz I thought it was t'other way around (HDD more reliable).
Anyway glad I future proofed and went all SSD - now see it's an even better decision than first thought.
Also noticed on Amazon the 256 G m2 SSD was $40 more then the 512 G.
- curious if caused by entry level laptop demand or losing interest in manufacturing smaller?
...lowest $/G still seems to be around 2TB - still with that quite a large $/G jump from 2T to 4T
6T spinners are cheaper than rocks (incase you're looking at paving your driveway etc),
... how cheap per GB can spinners get?
after many otherwise intelligent sounding suggestions that achieved nothing the nice folks at Technet said the only solution was to low level format my hard disk then reinstall my signature. Sadly, this still didn't fix the issue!

Current generation HDDs have exceptionally high density of data, that clashes with the inherent imprecision of high speed electromechanical systems.
Yet 6TB in a 3.5" format for 200€ or less are quite unbeatable. They are the modern equivalent of DAT tapes in most scenarios.

In my experience a good quality spinner (like the Western Digital Black series) is not only more reliable than most SSDs, but when they fail, the data can in most cases be recovered by running chkdsk. When SSDs fail, they tend to fail utterly. In other words nothing can be recovered.
I use SSDs for the speed, but I keep my system drive well backed up by regularly taking an image of the drive (using Macrium Reflect) and I keep my data drive well backed up manually. I keep the backups on an external WD Black spinner.

In my experience, HDDs are very, very reliable.

...unless "Seagate" is written anywhere on that drive.

Nahhh, I suppose there is one (or even a couple of) Seagate in the bunch of my very very (very) reliable hard disks. 
Hard disks simply didn't fail, in my experience. I have many of them, and some are pretty dated.

I can realistically only speak for myself. I've only ever owned maybe 8 Seagate drives. Right now I'd say at least 5 are dead, and I can't bring myself to place much faith in the remaining ones.
Every other drive I've ever had (50+, at least), with few exceptions, is mostly Western Digital, and I don't think there's a single one of them I've stopped using because it died. Plenty have been retired because they're now so small they're no longer worth using in any machine - but they were still working the last time they were hooked up to a system.

Been using Seagate since back in the 90's when they were Maxtor, been rock solid. Only issues I've had have been Desktop Barracuda drives running 24/7 for 3.5 - 5 years in a FreeNAS box and they started reporting dodgy sectors. Replace and they keep running.BR>

At one point in time they were okay. "The 90s" started 30 years ago.

And I've using them almost exclusively since then, I think it was 1993. I didn't use them once or twice in the 90's.
SSD's I pretty much use Samsung, but not enough time has passed to know if I've chosen good yet.

I heard that too. Despite that, when I buy drives for myself here at home, I buy them in sets of 3 for my NAS (one live, one offline backup, one off-site backup). I can't say I've ever had any such issue (multiple drives failing at roughly the same time). I've been doing this starting with 2TB drives, 3, 4, 6, 8 and now 10TB drives.
That being said, this does mean there's only one of them running 24/7, and the other two are only being used for the duration of a backup update (one once a week, the other once a month, then they get rotated). So they get used very differently.

Yes, I'm definitely referring to drives with same or similar runtimes

When SSDs die, they die completely and without any warning. While they are great, back them up often my friends.

Whilethey are a little less reliable, and use more power
I suppose that depends on what they mean by "use more power". I was recently looking to add external storage to a PI4, and wondered about the difference in power usage between an HDD and an SSD. That led me to several sites like this one:
Does an SSD or HDD Consume More Power for Your Computer? - The Revisionist
The upshot is that an SSD uses more power per unit time, but since you can restart an SSD far quicker than a HDD, you can get good power savings by powering down an SSD after only a short idle time.

I don't think it will be long before SSDs of some kind will dominate the market. Prices are dropping steadily. I got a 1Tb SSD just before black Friday for around $90, odd that I got it cheaper than listed on black Friday.

I just heard in the news that Italy is starting lockdowns too... I hope it is not that bad as in china, though.

It's quite mild and the dead were all people who would have died with the common flu (which made 217 dead per day this year).
Panicking people, idiotic regional governments and bad practices are what's causing damage. Consider that from my own experience Italian people are the most egotistical I ever known (there is a name for our condition which is "amoral familism") so raided supermarket and pharmacies are the norm even in region that are completely out of the hot zones.
Sadly our headless chicken reactions (and the press, which on the bests day averages at Daily Mail quality) are causing a lot of political and social damage. We are at the fouth case of asiatic people beaten in the streets for no reason and the embers of our ancient divisions between north and south are now flaming once again with open racism from italian to italian.

Sad to read that... I hope it doesn't escalate too much.

Call me nihilistic but I almost hope it escalates and explodes. Maybe restarting from the ground up something changes for good.

After the Black Death, the survivors (and their grandchildren) could still look up a lot of previous knowledge in pre-Black-Death writings. Later, when the printing press had become a household item, almost all knowledge could survive, in the form of books, a thirty year long closedown of society caused by an epidemic.
Today, you can't just pick that .pdf down from your bookshelf and thumb through it to find what you need. Your PC must be operational, your screen still working, "someone" must be able to start up the power plant. Someone must provide the oil, coal or whatever fires the power plant. The great majority of the information is not on your local harddisk, so someone must keep up the network - every single node between your PC and the database you want to access ...
An epidemic comparable to the Black Death would certainly affect both power plant workers, PC service men, DevOps personell at the data centers, fuel oil vendors and lots of other people that must be around to ensure your access to Wikipedia. Or to the schematics and construction drawings for that motor. Or to the service manual for the failing power generator.
That is what worries me: The number of people and professions required to ensure access to almost any piece of information. Or rather, how few deaths - a far lower percentage than the Black Death - it would take to paralyze all information access. How little of modern technology and knowledge is accessible in non-electronic form.
If we expericence anything like the Black Death, we must cross our fingers for society to be able to recover before optical fibers are all glass crumbles, before power generators have corroded away, before the hard disk bearings have deformed due to not being activated, ... A generation after the Black Death, society was essentially still in limbo. I very much doubt that we would be able to recover much info from the internet databases thirty years after they were last accessed. (Alan Weisman: "The World Without Us" is rather scary, when considering the effects of a pandemic.)
The best we can hope for, is to find scraps of old books in what remains of classical libraries. Most likely, we will find very little that is more recent than 1960s-70s technology, and even though we can read e.g. about transistors and vacuum tubes, we probably cannot make more of them; the library books do not tell much about how to build a semiconductor factory.
So for all practical purposes, in a restart from the ground, the ground is not much above stone age technology. Even though we will be sitting on piles of technological scraps, our chances of utilizing those scraps is very close to zero.

But that never really went away; it was just pushed to a back burner.
It's (some people find this surprising) the same in the UK.

Considering the relative size of UK vs Italy and the number of regions Italy is made of I don't find it surprising at all. 2 Italians form 3 political parties.
