For a long time now, the humble computer hard disk has been left behind in the development stakes. Processors, RAM, graphics cards, screens, Front-side bus, etc have all been getting faster and better. However, the hard disk hasn't really kept pace. Yes, OK it has increased in size and decreased in cost, but it has not really gotten any faster.
How often have you nowadays been waiting for your application to start up, only to watch the HD light just constantly flash, and you can hear the drive churning.
Well, it looks like there is a bright light on the way. Solid State Disk (SDD). From Wikipedia, SSD is defined as:
"A solid state drive is primarily a data storage device, for use in computing applications that traditionally use a hard disk drive. A solid state drive is based on either non-volatile memory or volatile memory instead of the spinning platter and mechanical-magnetic head found in a conventional hard disk drive. With no moving parts, a solid state drive eliminates seek time, latency and other electro-mechanical delays and failures associated with a conventional hard disk drive."
To me, I describe it as a solid state drive is basically a lot of RAM put together that doesn't loose the data when not powered.
I have then found an article on http://www.coolest-gadgets.com/ that gives some details on the size and pricing of some of the early manufactured drives. The article goes on to say "No word on pricing yet for the 32GB, but the 16GB weighs in at a hefty $250.00. With a range of SSD cards from 8GB – 32GB". I can't wait until we get as common place these drives in every day electronics, such as laptops, iPODs, Mobile Phones, etc.
