Big enterprises are often the last adopters of most technology, with some of them relying on 5, 10 or even 15 year old hardware simply because it works. That's not the case with Google, who is planning to roll some of their servers over to the relatively new to market SSD technology. The decision was made to take some of their servers and switch their mass storage systems over to solid state disks in order to reduce power consumption, something that could have a huge impact in a datacenter environment.
The drives themselves will be supplied by Intel, though no specific mention of storage capacity is made. The surging demand for SSDs could certainly see more manufacturers getting interested in this market, and having a huge tech company like Google willing to put their data onto SSDs can only encourage others, who might be willing to spend the money but are fearful of reliability problems, to follow suit.
