A breakthrough in NAND flash technology will increase standard 2.5-inch SSDs to 10TB and drastically reduce their cost in the process Standard consumer SSDs will increase up to an astounding 10TB of storage, thanks to a new type of 3D NAND flash memory that Intel and Micron introduced Thursday morning. The two companies, longtime joint partners in NAND flash development, said the breakthrough isn't to make larger flash chips, but thicker ones.
