Recently SanDisc announced that, through a partnership with Toshiba, has presented a technical paper for a flash memory chip that stores 128 billion bits of data. This is on par with the current highest capacity Blu-ray format with the 128GB BDXL media.

At present, optical media has enjoyed a comfortable lead as the cheapest per byte method of data storage. Additionally, outside of hard drives, optical media has long held court as the largest capacity recordable media as well. With SanDisk’s announcement, this ups the ante in the battle between optical and flash for storage supremacy.
