An anonymous reader writes: Reuters reports that Western Digital will buy SanDisk in a deal worth roughly $19 billion. In a press release, WD said, "The combination is the next step in the transformation of Western Digital into a storage solutions company with global scale, extensive product and technology assets, and deep expertise in non-volatile memory (NVM)." SanDisk has been in business since 1988, and primarily "manufactures flash memory chips and other digital storage for personal computers, data centers and consumer electronics, including smartphones and tablets." They have over 8,000 employees, compared to WD's ~76,000. This follows another major transaction in the storage market, when Dell bought EMC last week.
