I think you mean add nothing for the USB interface and $1 for the \"case\". This was a USB memory stick, not a hard drive replacement. But thanks for the $50 figure. In the meantime I\'ve wiped an old drive that was storing stuff I don\'t need anymore.
I tried a microSD card with 1 TB for $10-ish, and a USB dock for it for about $1. The SD card, with the same
h2testw, actually got to day two of testing (about 300GB) before it faulted. It\'s not a mislabeled item, or complete fraud,
just a low-reliability card (this was Xiaomi brand, and less return-able than an Amazon purchase).

It\'s pretty inconceivable that a 1TB drive could be sold for $10 unless it used defective chips (rejects). One way or the other, this is a fake part.
I got two of these supposedly 2 TB sticks. They were definitely
fake. I was stupid for even thinking you could get a 2TB stick for
under $75. I\'m not sure you can even get one for $750 ??
That\'s the problem. The quality is not related to the price. That\'s why I test all the flash devices I buy, regardless of price.

Ah OK so youre looking for intersection of
- 100% reliability,
- accurately-stated capacity,
- and low purchase price.
Those requirements tend to correlate with established brands
of product, and reputable vendors.
User reviews on a platform like Amazon, are poor indicators
of those factors. (research studies supports that).
Of course I respect your desire to \"test the marketplace\" and
challenge these things

I recently bought a couple of 1Tbyte SSDs (Samsung 850 PRO) on eBay. One of the
suppliers was impatient for feedback. I told him to wait until I had written a few Tbytes
of random data and verified it (after updating the firmware and using the Samsung
diagnostics to check for fakes). Both suppliers had two drives for sale, but I bought
one from each to reduce the risk of correlated problems in a RAID array.
Both had been heavily used, but still had more than 90% of their rated life left. I see
this as getting somebody else to do the burn-in testing for me!
One interesting issue that I came across was that one of the drives initially had a much
lower write speed than normal. It recovered after I had written data to all locations. I
think it must have been in a system without TRIM activated, so every write needed an
erase first.

It\'s weird that you draw the conclusions you do from the post I made.

BTW, the \"stated capacity\" being faked, doesn\'t mean you get a smaller device. It means you get a worthless device. If the drive thinks it\'s 256 GB, but it\'s only 32 GB, what do you think happens when it tries to write anywhere above 32 GB? That\'s why all flash drives need to be tested. If they\'ve faked the capacity, it may work for weeks or months before you find it is crapping out in normal use.

Ok, thanks for the comments.

Well, it seems not. I picked a drive in a metal case to stand up to a bit of abuse and order two in order to get the free shipping.

I would have had to use a SD card to move it or I guess I could email it to myself. So I tried calling Amazon to see if they could just email it to
me.
The person on the phone was a bit hard to understand, but eventually we communicated. In the end, after I asked for this vendor to be reported, she said she would do that and also gave me the refund without a return. >> >> So in the end it worked out, but Amazon doesn\'t make it easy. I guess if I were a high volume Amazon customer, I would know how to make it all easy, and would also be able to give this outfit a bad review. But I\'m not allowed to write reviews until I\'ve spent $50! >> >> So much for buying at Amazon. >>You didn\'t say how much you paid for them. But from guessing, it\'s 2x 512G for less than $50. You got what you paid for.Rick\'s life seems to be centered on cheap. He said his dad was likethat too. Could be hereditary.

I stay away from \'cheep\', you waste too much time trying to make
it work.
