Seagate Technology will increase investments in its manufacturing facilities in Shenzhen to US$122 million from $20 million during the next three to five years. The investments will be spent on new production equipment and additional investments in the Shenzhen facilities. 'It is critical that Seagate disk-drive factories are capable of ramping up and producing quality disk drives in high volumes quickly and efficiently and our China facilities have demonstrated their ability to achieve this time and again,' Seagate vice-president Eddie Lui said.
