Does advertising a product as adhering to some standard, but secretly knowing that it doesn't 100%, count as e.g. fraud? I.e., is there any established case law on the matter? I'm thinking of this example, but also more generally USB devices, Bluetooth devices, etc.

I was under the impression that a lot of off-brand USB devices didn't use the USB logo specifically to get around certification requirements. Basically, they just aren't advertising adherence to a standard. No idea about NVMe or BT.

The USB trident logo doesn't need certification. The other, usually coloured, logos do need certification.

Where are you seeing counterfeits? AliExpress, Ebay, Amazon?

Probably chinese sellers on all those sites. I've noticed a common thread with people who complain about counterfeits is that they're literally buying alphabet soup brand fakes from chinese FBA sellers instead of buying products directly sold by amazon or from more traditional retail channels.

There’s definitely a problem with my grandma or some less-technically educated person buying “alphabet soup” fakes, BUT Amazon does commingle inventory. This means that lots of people can end up with fakes sold by 3rd parties when buying from a reputable brand.

There were even stories of those crazy coupon people reselling on Amazon, and some cases of returned retail products ending up as “new” on Amazon. Which gets problematic with certain things like consumables (the WSJ did an article on toothpastes iirc).

Yes, and the OP did abide by HN guidelines. But GGP implied that the title was misleading; but it was the original title! So, what to do if the original title is misleading? Admittedly this is a twitter thread, so no "actual title" exists.

>So, what to do if the original title is misleading? I'd suggest posting an alternative, non-misleading source instead, or if none exists, don't post at all.

Personally, I _do_ editorialize by posting a “summary” of what a post discusses, if there’s no real title. I try not to make it pass as my own opinion; sometimes it happened that mods reverted it to the original, less relevant title.

SK Hynix is the #3 flash manufacturer (acquired Intel's NAND biz), and their RAM is quite decent. i wouldn't think twice about buying if it wasn't for this report.

Hynix's flash is just fine. It's the controller at fault for this.

In one of the tweets he says another drive with the same controller passed so it's not just the controller

Twitter yuk, can somebody just post the names of the four tested drives and which passed/failed please?

We should just say X. Not "X (formerly Twitter), not X-itter, or anything. It's called X, if that name is stupid and unclear that's on them.

> there any established case law on the matter Always makes me laugh. Anyways, not in the US where you're probably asking for, but yes, the vast majority of the developed word has that. It's called "false advertising", and exists at least in the EU, Australia, UK. You can't put a label on your product or advert that is false or misleading. So if the box says this is a WiFi6E router, but it's actually only 5 because i…

That’s not really what the commenter was asking. That’d be false advertising in the US too.

I think the question is less “if they skip on parts and lie” and more along the lines of incompleteness. Like “it’s an HTTP server, but they saved on effort and implement put as post, which works fine for most of use cases”.

That said, I’d guess this would be a pretty hard case to win. The law typically requires intent when false advertising, so if they didn’t know they didn’t follow the spec they might be fine. And it depends on the claims and what the consumer can expect. Like, if you deliberately don’t say explain the exact spec your SSD complies with, and you make no explicit promises of compatibility, it’s a harder win. Like I bet few SSD manufacturers will say “Serial ATA v3.5 (may 2023) tested and compatible with OpenXFS commit XYZ on Debian Linux running kernel version 4.3.2”. But if they say “super fast SSD with a physical SATA cable socket”, then what really was false if it doesn’t support the full spec?

Misleading headline since after testing eight more drives, none more failed. 2/12 is not nearly as dramatic as “half”, and the ones that lost data are the cheap brands as one would expect.

SK Hynix is a major brand and the P31 is a great midrange SSD... except for the fact that it seemingly doesn't care about your data.

I have a Sabrent M2 in my own PC, bought it because it was the cheapest option. Incidentally I suspect it's the cause of system-wide slowdown in the past few months, even opening the file explorer takes over ten seconds sometimes.

I’ve similarly seen a lot of “TF card reader slots” instead of “micro SD card” slots.

imo hackernews should just automatically replace twitter.com with nitter.net even if just for readability without logging in's sake: https://nitter.net/xenadu02/status/1495693475584557056

Is nitter.net still functional for you? The service was accessible earlier this year from my location but now it is all 403 Forbidden.

nitter.net is, the mirrors are not.

iirc, twitter turned off all anonymous access, unless you come from a search engine, then you get a limit number of requests. So zedeus came up with an idea to make a massive pool of search engine'd api tokens and use those to keep nitter up. The mirrors would have to copy that idea, and few (0?) have atm.
