While I agree, it's been hard filling up the 2TB drive in my laptop. My home server has a couple dozen terabytes (on spinning metal) and, with current fill rate, it's predicted it'll need an increase in space only after two of the drives reach retirement according to SMART. It hosts multiple development VMs and stores backups for all computers in the house. Another aspect is that the total write lifetime is a multipl…

Oh look at Mr. “I pay legitimate streaming services for all my tv shows and movies” over there. (= I have a 12 TB NAS that is 99% full at the moment. Should I delete movies I may want to watch later, knowing full well they aren’t easily available on the streaming services I pay for? Ha. It fills fast!

They have 16TB NAS drives for $300 now so if you have decent disposable income just upgrading the drives one by one is probably a decent strategy.

It's QLC NAND (~1000 program/erase cycles from https://www.purestorage.com/knowledge/what-is-qlc-flash.html ). eesh. [Update] from https://www.anandtech.com/show/20007/samsung-teases-256-tb-s... : "Samsung's 256 TB SSD is based on 3D QLC NAND memory and probably uses innovative packaging to cram multiple 3D QLC NAND devices into stacks." 3D QLC should have higher endurance than regular QLC. We'll have to wait and see…

It is very eesh. But tbf, I would precisely use this for single-drive monthly cold storage backups of a large raid nas for example.

I'm curious what form factor the drive is. I've wondered if you could squeeze a bunch of m.2 SSD's into a 3.5 HDD case, how much capacity you would have. I wouldn't be surprised if this SSD ends up fitting the 3.5in standard form

I'd worry about heat issues doing that.

NAND doesnt work for cold storage.

The bit that everyone likes to leave out about the 3 months at 40C retention standard is that it applies to drives at end of life, with all their rates write endurance used up. Drives that are not so worn-out have much longer retention—and a drive used only for cold storage of infrequent backups would hardly use any of its write endurance.

The recommendation to have the drive be powered up for two weeks after taking it out of cold storage is only so that the drive can do it's low-priority background checks of data integrity. If you do a full scrub of your data from the host system, you don't need to worry about that, because you'll be giving the drive all the same opportunities to discover bitrot.

None of the above changes the fact that SSDs are still quite expensive for cold storage purposes.

I think the current replacement for 3.5" style drives is done with the U.2 connector / form factor (?). https://en.wikipedia.org/wiki/U.2 Not sure if anyone has maximized the space like you're thinking however.

I think all the record-setting high capacity drives have moved over to EDSFF E1.L "Ruler" form factor, though I'd also expect 64+TB drives to be offered in EDSFF E3 sizes that are the more direct successors to U.2/U.3 2.5" form factors.

I was looking for some 8TB m2 drives recently and they are still surprisingly expensive, considering you can get 2TB ones on sale for less than $100. But there are barely any options too, still a niche market https://pcpartpicker.com/products/internal-hard-drive/#A=600...

Those $100 2TB drives are probably because of this: https://www.theverge.com/22291828/sandisk-extreme-pro-portab...

I also had a problem with Sandisk 2TB portable SSD. But it dies for a few days and comes back. It's wired. I will not keep anything important in that drive after this incident.

I can absolutely tell the difference and it’s frankly annoying to collect something which will become obsolete not just within your lifespan but when you’ll likely have a lot of lifespan left to go. 4K blurays to me hold up compared to 5k/6k/8k raw footage to the point I wouldn’t be too troubled if I had an old format on my NAS when an h.267 8k version came out. You can have a great experience by streaming videos dir…

you know, I’ve never actually bought a bluray video before, maybe I’ll pop one in my ps5 and see if I’m blown away, or more likely if the other sources start having things I cant unsee I did recently get back into piracy, and did a couple comparisons since I figured 4gb h265 is so last decade, and I really wasnt amused by the larger bluray rips. I have 20/10 vision acuity and can also see a broad vivid colorspace. I…

Honestly if we compare a 10gb compressed re-encode to a 4K bluray rip or remux I would have trouble telling the difference but 4gb is pretty small especially for certain kinds of movies.

There’s certain scenes where I can definitely see compression artifacts or whatever and others where quality differences cannot be noticed.

Btw, since the thread is about both Samsung and SanDisk now, I can tell a personal experience with both regarding the same kind of issue.

I had the exact same problem with SanDisk as explained in The Verge article. I had it in January, before it became a known major issue, so I guess they were not prepared for that. However, the process was smooth enough, and I just filled a ticket with details, received a couple of questions, send it to their service center and received a new one later. It works fine now.

But I had a similar situation with Samsung SSD too, it died after a couple of months. But they made it impossible to replace it. The process is so bad that I was never able to get into any support for that case, and never received any meaningful response. So I just gave up eventually, so I guess I just donated few hundred dollars to Samsung.
