I'm not surprised to see only capacity and speed being mentioned, but nothing about reliability. I wonder what the endurance and retention is like. Possibly PLC flash? I remember reading that PLC wears out in less than 100 cycles per block, with retention measured in months or days(!) depending on temperature. These aren't SSDs so there's no expectation that they'll be powered on most of the time and can self-refresh. At 104MB/s it would take over 10h to transfer 4TB, and likewise 20h to transfer 8TB. I'd rather they offer 2TB SLC SD and 1TB SLC microSD cards at the same price, which they could if these were QLC.
