SanDisk, in a joint venture with Toshiba, sells almost half of the world's flash technology but enterprise storage users can be forgiven if they don't associate SanDisk with flash storage systems. Most of what SanDisk sells goes into mobile devices. You probably have flash memory in your smartphone and don't even realize it, or at least don't think about it. Going forward, SanDisk is determined to enter the systems business too, noted Allen Samuels, chief software architect of SanDisk's emerging storage solutions, in his keynote at the Linux Foundation's Vault storage conference this week in Boston.
