USB memory sticks. Too good to be true?

I see USB 3.0 rated memory sticks with claimed capacities of 1TB or 2TB advertised on Ebay for prices below £5. Are those capacities genuine? I believe rogue suppliers in the past have been known to sell other sticks which show up on Windows as having the claimed capacity but in reality have a much lower capacity.
Are the sticks likely to be fakes or rejects at that price? Anyone here had good/bad experiences with them?

If 1 TB is written, then at least 0,8 probably will get, that is first
Second - somehow wonder may it be so much cheap - then I want it as well.
Third - probably the main reason is hunger, because the most of Chinese plants are stopped to work before vaccine is ready.
Anyway, handle it with a care; was written that is demonstrated - money may carry (transport) a virus. It automatically means the postal packs may carry it as well, in contrast what was said previously. In today news was written, US Army got command to be ready use a force homeland, if the virus will spread there. So better dont joke being first Wuhan "clientele". As shows the this evening news, even face-masks are not effective against this plague.

I suspect they're counterfeit. I bought some 64GB microSD cards that had an actual capacity of 8GB. They may be employing a similar trick on USB drives.

If anyone buys one, do some tests and let us know...

Less than 5 Pounds is unrealistic even for 3.0. Yes they can be had in Terabyte size, but not cheap. The key is the throughput rate. I would suspect, at that price, they may be 2.0 design and 3.0 compatible and at a very slow rate. YMMV

RE:""I bought some 64GB microSD cards that had an actual capacity of 8GB""
Oho!! I knew that 2,2 Chinese kilowatts may be easily fed by two AAA finger-batteries for whole week if not month, but I didnt realized its true even for memory sticks....

I bought 3 sticks with 130GB last year from China. 2 died in 1 week, 3rd died the following week. Don't trust it as the sole backup for valuable files.

Not only are they fakes, they might even come with a free virus. In a best case, they write the firmware to report sizes larger than they actually are.

And once you use the actual capacity, they start overwriting data. I use the counterfeit cards to shuffle data around. I just need to make sure I don't fill the actual capacity and start losing data.

I have purchased tf cards on ebay with a claimed capacity of 128GB.
Under Windows operating system they show as 128GB, but have been spoofed to do this (they were actually 32GB cards).
I have software to test the memory, it does not show the claimed memory capacity to be spoofed, but shows only 32GB to be ‘good’ memory.
I complained to ebay and got a refund, with the seller’s listing removed.

I only purchase memory sticks from Micro-Center and I have not had problems with any of them yet.

'ebay' was your first clue....

The software I use to test is ‘H2testw’ – free downloads are available from a number of websites.

The scan time very much depends on the PC access time to the memory device; genuine 128GB takes a few hours (write then read).

Once the software encounters corrupt write/read errors, things slow dramatically as the software reports the errors; corrupt 128GB (actually 32GB) took over 10 hours and counting – showing only 32GB good.
