tl;dr I see one brand name being mentioned in this thread. Is Sandisk still a good name to go with ?

How is this not a FTC violation to begin with? If I order a Samsung 860 Pro then I should be getting MLC cells, so why would it be okay to swap them out for TLC instead?
AFAIK Samsung has its own fab so they are not doing this.
The problem is those vendors that only buy flash memory from other fabs and have to swap them for others when they can’t get the same cheap offer again.
Ah I see, thanks for explaining that to me. :)
AFAIK, MLC is used sometimes as a global name for MLC, TLC, QLC, etc.
This is what I have seen from Samsung but you can always check which kind of MLC uses.
Edited: this was taught to me in the first year of SysAdmin vocational training course in a class while explaining the insides of a SSD.
Indeed typically it will be MLC 2, 3, 4 and soon 5 bits (or PLC). At least they will tell you how many bits is in the MLC.
Yes, that is the thing i was referencing when I told that you can check which kind of MLC uses, by the number of bits.
Thank you very much for reassuring me of that. :)
This is old news. If you buy cheap rebranded SSDs this is a risk you have to deal with.
Except it’s the biggest SSD vendors doing this.
Samsung is not doing that AFAIK.
Yeah, if they fab all their own components then it’s a lot less likely for this to happen, but a large portion of the biggest players don’t fab.
Well as I said, cheap rebranded SSD… anyone not fabbing themselves is clearly in that category. They might sell a lot, but that is because they are cheaper.
Both the title of this post and Linus’ title seem like mild clickbait. The “real world” performance benchmarks of the modified SSDs were actually slightly higher than that of the early review copies, and I think it’s reasonable to believe that the changes were made for supply chain reasons rather than to save a few bucks (at least in the Adata case; the PNY case he mentions briefly at the end seems much worse).

I don’t get the hate towards him tbh. He’s obviously not perfect, but they’re one of the least shill mainstream tech channels. They also went to a lot of effort and did their own independent investigation for this video.
I already deleted the two comments.
To be exact, even disagreeing with seeing this person’s content, I think that my comments were not respectful.

As someone who just had an SSD fail, makes me wonder if this phenomenon might have had anything to do with it… WD drive it was. Tech manufacturers are not your friends!

Depends on the IO requirements. For lots of reads and rare writes SSDs are usually better because they don’t have moving parts. HDDs are better for cold storage, as SSDs lose their charge over time.
HDDs are not ideal for long-term cold storage either due to data rot, the magnetic charges on the hard drive platter that encode for 1 or 0 lose their magnetism over time. I’ve read that data rot can start to occur in as little as 1year if the data hasn’t been “refreshed” by powering the hard drive on and re-writing all the data.
There are some archival-grade hard drives, but if you have data that you don’t want to store in the cloud and don’t access often an LTO drive is your best bet. You can get LTO tapes certified for 30+ years of cold storage, but the catch is that reading the data is super slow… and the tapes themselves are super flammable.

Exactly, and with SSDs that can happen after a few weeks (!) of not turning the thing on. The only really reliable way is probably compressing and encoding it into literal granite.

Yeah, We had one of those we couldn’t read because some dumdum stored it sideways. The bits literally fall down, so you have to store LTO drives like this:
|and not like this:_;)Cold storage is a science in and of itself, there’s college courses for archivists about storage formats. tl;da: use several media and copy it around with checksums every few years. Keep the data luke-warm, not ice-cold.

HDDs have SMART, and that makes them.better than SSDs
Yeah, because SSDs also have SMART. The metrics are different.
Removed by mod
SMART is an interface standard implemented by the HDD or SSD controller. The implementation is proprietary for almost all HDDs, too.
