Research into the field of light powered computing has made some considerable strides as of late. Most notably, the science behind a laser powered hard drive has been more solid than ever before.
A laser powered hard drive would work on the principles of picosecond pulse lasers working where magnetic read/write heads would (something that was considered to be impossible until recently). Drives working on these fundamentals would provide a 1 TB/s transfer rate with their first generations, and others after that would reach speeds of 100TB/s and over.
Supposedly, this technology will be available within only five years, but like most laser technology, we’ll believe it when we see it.
