Below is the list of the biggest memory cards; there are eight memory cards that have a 1TB capacity, four SD and four microSD. At the time of writing, the highest capacity microSD or SD cards are:
Lexar Professional 633x 1TB SD card
SanDisk 1TB Extreme microSD card)
SanDisk 1TB Ultra microSD card
SanDisk 1TB Extreme PRO SD card
PNY 1TB PRO Elite microSD card
Samsung, HP, Teamgroup, Micro Center, Netac and Patriot are the other trustworthy memory card vendors that sell 512GB microSD and/or SD cards but have yet to announce any plans to sell 1TB models.
It is worth noting that there are sadly, dozens of fake 1TB and 2TB memory cards available on open marketplaces such as eBay and Amazon for rock bottom prices. It goes without saying that we strongly discourage anyone from purchasing them; they are essentially just a big, fat scam.
