Most of the brands are just rebadges, there are not that many NAND manufacturers.
The following were the largest NAND flash memory manufacturers, as of the second quarter of 2023.[26]
Samsung Electronics – 31.4%
Kioxia – 20.6%
Western Digital Corporation – 12.6%
SK Hynix – 18.5%
Micron Technology – 12.3%
Others – 8.7%Note: SK Hynix acquired Intel’s NAND business at the end of 2021[27]
Kioxia spun out and got renamed of Toshiba in 2018/2019.[28]
Do Lexmark make SDs? There is Lexar, but they came out of Micron and are usually liked for a budget brand. I think they make their own NAND now.
