    • Excellent, legitimate cards
Capacity: 128 GB Style: Adapter Included
These are legitimate. Well, as far as technical concerns go... I picked up two 128gB units Bought two units, both test to expectation with throughput (saturated my USB 3.0 adapter, didn't test with 3.1) and show proper logical topography. Transfer size total I used was around 120gB, verified without issue. The overall performance is about the same as my legitimate SanDisk 128gB card with nearly the same ratings, but a little bit faster. This stuff (proper testing per unit) is critical, as there are a quite numerous volume of bogus cards out there, enough so where you can use "If it seems too good to be true, it is" as a rule, NOT the exception. These are almost always easy to identify; the volume will have a total space that isn't a factor of 2 (eg, you buy a 512gb card, and the track count times sector size comes up to a round 500gB exactly, when it really should be about 524,288mB, but this varies based on alignment and how the factory formats the shipped partition... Anyways, a real, non-hackes firmware card will NEVER have that kind of structure, literally never, and if you see that, you're looking at a dirt cheap sub 2gB card that's had bogus firmware flashed to it to either cycle back to the first sector on write to make you think it's working, or it'll just flat out fail when you hit the real cap). These are the real deal. They have good performance, and should meet the majority of needs.$10 a piece is a fair price. ... show more

    • Not 100% confident
Capacity: 128 GB Style: Adapter Included
It’s strange. It works sometimes with certain things. I can’t figure that out. It’s a good value but I still back up whatever I store on them. They are not something I would consider reliable for the long term.
