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 :-)

(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. John

(research studies supports that). > Of course I respect your desire to "test the marketplace" and > challenge these things :-)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.

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. Amazon makes it hard to get the free shipping without signing up for their master plan that's over $100 a year now.
