Unfortunately, after a couple weeks of use, the SD adapter mine came with split apart at the seam. No obvious wear, no pressure on it while it was inserted. unsure why it split, but pressing it back together doesn’t appear to do anything.
2.9 of 5 stars on Amazon...

I believe he is taking about a camera, which is why these cards are needed.
I ended up joining the drop BTW...I wish I had a camera like that...
What's the expected read/write longevity of these microsd cards? I'm not expecting them to outlive my SSD drives, but how much data should I expect to be able to read/write before I need to think about replacing?
The internet says modern cards may have up to 100k write cycles, which sounds a bit exaggerated to me.
I know for fact however that in the old 8-32GB days, they had about 5k writes, so at a minimum you're looking at 625 TB written on a 128GB card before it starts dying (assuming the writes are spread equally).
Update after reviewing additional take-away:

Great price. I had a adata memory card in the past and no complaints.

Some reviews I found.. speeds as advertised when fresh/formatted, however degrades to about half equaling UHS-1 speeds found - which is what TheProfosist noticed with his below. Just reformat before requiring the fast speeds using the
Got mine today 3.31.18 in the mail. Lifetime warranty, 4K video writes at 155mbs with backwards compatibility. I'm satisfied.
Received my cards to day and the 128GB card will not run at UHS-II speeds. The 256GB will no longer run at UHS-II speeds but did initially. I have no idea if it is the cards or the adapters as nothing I have that is microSD UHS-Ii native can do a speed test and the only adapters I have are the ones I was sent. @Adata

Are you going to test with a 3.0 compact memory card reader in addition to theirs? I have one of those but none of my equipment USB slots are marked UHS-II , simply USB printed on camera side. At the very least i do know their stated output specs. of 100mbs at 4k H.264, other than that, "deeper" specifications are not available to me.
THIS FLAG by Crystal Disk Mark: CrystalDiskMark 4-6 uses Microsoft DiskSpd (The MIT License). So, the benchmark result is NOT compatible with 3.0.x.
  • The result depends on Test File Size, Test File Position, Fragmentation, IDE(PATA)/SATA/RAID/SCSI controller and CPU speed etc…

hope these live up to their numbers as they as like half the cost of the equivalent Lexar cards.

yes you can still buy cards that have stock. SanDisk are similar if they have a card of that speed. Many ex-lexar people and some SanDisk people made Pro-Grade Digital (worst name ever IMO)
My other 128gb card is a Lexar, got this one for the 4k +100mbs speed.
I'm giving this one a shot. If it writes over 100mbs I'll be a happy camper. Still wondering if the cameras will accept it but we'll see. Update: card is backwards compatible so at my sensor's output "worst case" it'll revert to uhs-1 speeds i guess.

No, Standard slot. The camera is a Sony sensor packaged for UAV such as the Inspire 1 Pro and Matrice 600 pro I fly. Company stated max is a 32gb card but i have a Lexapro 128gb running just fine for 4K video. Max camera output is 100mbs H.264.
I anticipate this card allowing for more detail, but we'll see.
Not many people ( Clients ) seem have 4K viewing capabilities, which is frustrating when you're trying to show them your 4K work.
Received it today 3.31.18 and says it is also backwards compatible with a lifetime warranty included so not looking for a mismatch problem. "States 160 minutes at 100mbs ultra HD 4K".
do you how i can check the total price with shipping to Canada ?
Join the drop and on the checkout page it will show you how much the shipping charge are.
thank you !
