A part of me will see stuff like "3TB Flash Drive" on AliExpress for $3 and briefly consider buying it. Like, I know it's obviously not true, it's obviously a lie, but I also am curious about what I would actually get.

I never do it because I don't really see the point of paying money for something that will immediately go into a landfill, but it's always tempting.

A few sellers on eBay are honest

  Description:
  This item is upgraded by 32 GB Pen Flash Drive to 2TB
  32GB-2TB, the actual capacity is 32G, the computer displays 2TB, the detection is also 2TB, more than 32G things can be stored, but not displayed.

  https://www.ebay.com/itm/234810575961

That's not bad. Most counterfeits I get are just 2GB so hardly useful. Still, the counterfeit firmware makes compatibility issues more likely, so better to buy one without the counterfeiting.

> more than 32G things can be stored, but not displayed.

That's certainly an interesting way to phrase it. I use /dev/null for a similar purpose with the added benefit that it can store petabytes of data, but sadly we don't have the technology to display it yet.

Lol. That's up there with the [1-bit Bloom filter](https://www.xkcd.com/2934/)

>A few sellers on eBay are honest

no, that's not honest, farthest thing from it, that's what makes it an actual scam. by having that in the fine print, you can't return it, and they won't be flagged.

I don't think buyers of these SSDs want to return it. The only reason to buy such an SSD is to resell it. Effectively they are enabling other scammers.

You can certainly return an item if the title of the listing was inaccurate.

In my experience, eBay won't "flag" dishonest sellers of counterfeit storage products, anyhow. I tried to get a listing selling counterfeit Samsung micro SD drives taken down, but eBay did nothing. I was refunded, but the unsuspecting will continue to be duped.

In what world is a title that says 2TB for a 32GB drive "honest"? Is your view that a lie becomes honest as long as you add some truths after it?

It's a fact of life that titles can't always be a fully accurate description of the whole subject. Otherwise we wouldn't need the part that comes after the title...

> It's a fact of life that titles can't always be a fully accurate description of the whole subject.

It's also a fact of life that there is a gigantic amount of room between "not fully accurate" and "blatant lie"

But why would anyone want a fake 2TB though?

Surely they write this to cover their ass when people don't read the entire listing.

Makes backups cheap and easy. Also if you _know_ it won't restore, you stop worrying about whether it might or not.

what you are buying is a piece of paper with a picture of an XBox360 on it

The issue is that if you exceed the (invisible) limit, you start overwriting the existing data. That's Bad (TM), since there's no indication that it's happening, until you attempt to retrieve the data and discover it's corrupted.

The subject of this topic, f3, will quickly probe the drive, determine the true size, and create a partition on it of the actual usable size. Using that partition, you will never lose any data. If you try to create a partition in the rest of the drive, it will be immediately corrupted, no tools will show it as good, you won't ever be able to get around to putting data on it to lose it.

> will quickly probe the drive

Some scam SSDs are smaller drives with hacked controller firmware that is bright enough to avoid detection with quick scans - you have to write beyond the real capacity then re-read to confirm corruption.

Have you found cases where "f3probe --destructive" didn't work for you?

Not first hand, though I've used tools of similar intent and found the quick heuristics, while usually very good, not 100% reliable, and for storage I want to be sure not almost certain.

Note that I was warning about quick tests, I'll have to try “f3probe --destructive” on something next time I have some playtime to see whether I'd consider that quick! Of course, it could be much quicker than the full capacity write some tools use to find a defective or deceptive drive¹² but quicker and quick aren't the same.

If a quick test says the drive is fake then it is, and many fakes can be detected these ways, but it takes more to convincingly state a drive isn't fake.

[1] Only a little over true capacity should be needed for that, in the case where writes to anywhere up to capacity will work (which is common as creating a filesystem more complex than FAT/exFat often requires activity similar to what quick write/read heuristics do).

> Using that partition, you will never lose any data.

... unless/until the underlying flash fails. Which it probably will; there's every reason to expect these drives are made with the cheapest, worst flash available.

> more than 32G things can be stored, but not displayed

"Honest"?

> 2GB so hardly useful

I used to buy 2GB drivers all the time. The only reason I stopped is because it's hard to find anybody selling them.

It's plenty of space for a portable drive, it's enough for a Linux installation, it has lots and lots of uses.

But I wouldn't buy a 2GB driver that pretends to be larger. At least not willingly.

> It's plenty of space for a portable drive, it's enough for a Linux installation

RHEL9 installer is 10GB.

Is there any reason I would deliberately purchase one of these over a standard 32GB drive? Trying to think of if there’s a case where I would want to trick some hardware into thinking it has a 2TB drive when it really doesn’t?

They’re suppliers to other scammers

And there's honest stuff on there too, loads of it actually. I bought a 128GB SSD from there many years ago for $10. I expected nothing but like you say, I was curious about what I'd get and something faster than a shitty USB stick with decent storage capacity was all I was after. I verified it, and it works perfectly and it's 128GB as described, it just lacks cache so it bogs down on super large files. But for $10 I couldn't buy a better USB stick.

They may have true capacity but long-term retention is yet to be established: https://htwingnut.com/2022/09/11/ssd-as-long-term-storage-te...

There's even SLC USB drives being advertised, an otherwise extremely overpriced item these days, with sellers posting the exact part numbers and pictures of the insides as evidence. Those may be using recycled flash.

A few years ago Micro Center had a coupon for a free 120gb SSD, which I guess worked because I ended up going there and buying stuff in order to redeem it.

The SSD wasn't great, it was pretty slow, but it did work, and I have used it in conjunction with a USB SATA adapter as something where I can write lots and lots of tiny files for projects I work on [1], and where I don't particularly care if I break it. Surprisingly, it's still holding up...pretty good for free!

[1] One project I've done involves breaking up video files into a picture of every frame, then do some kind of image processing, write the new files, and then glue them back together, which means there can be a ton of writes on there that I don't want to be done on the expensive and irreplaceable internal SSD on my Mac.

For consumer stuff like this, you'll obviously get something else. But sometimes you can get recycled components if the price obviously is not sane, where recycling is an option.

It's only fraud if the description mentions new and original. :)

My trick to get decently priced computer equipment is to buy used stuff from data centers; generally that stuff will sell for pennies because their goal is to "get rid of it", not "get rid of it for a profit". Desktop network cards and switches are almost always available for very little (sometimes literally just $1 + shipping).

Look at govdeals.com for stuff from universities, they seem to sell a lot of their surplus hardware there.

Govdeals is sort of addictive. I've only bought stuff on there a few times, but it's fun to look around and see stuff like "pallet of 400 laptops" selling for $600.

When you say data centers, what do you mean? If I was looking on Craigslist or whatever for this, how would I be able to tell which seller is a data center?

How do you find such things? In person or online somewhere?

Sibling comment mentioned Govdeals, which is a place I'll look sometimes if I can find something near me or they're willing to ship.

You can look on Craigslist as well, especially if you live in a large metro area (I live in NYC so it's easy to find lots of corporate surplus). Companies will often need to upgrade all their infra and liquidate their equipment. My printer is a giant nearly 20 year old HP office thing that I got for $30 + $100 for the Uber back home from an office that did a full IT renewal.

Back when it was being done with external hard drives there were YouTube channels dedicated to breaking them open and experimenting with how they did it.

Fun stuff to watch on a boring afternoon.

The potpourri of a youtube channel, Atomic Shrimp, has done a couple interesting videos doing just that.

His channel is where I first heard of this scam.

I did this on Amazon knowing it was a scam and immediately returned it just to drive up their numbers and hopefully get them shut down faster. I have no idea if that did any good, but what disappointed me was Amazon only gave me credit, not a full refund.

Yeah, aliexpress returns real money.

TLC flash is currently less than $0.10/GB. $3 will probably get you a 32GB drive with flash of dubious quality.
