Just found this thread in Gizmodo about Toshiba has released 128 GM Solid State Hard disks.

First hard disk I had in my first computer had about 400 MB and the second one had about 8 GB and today it's over a Tera byte. Roughly it has taken over 10 years for us to reach the 1 TB limit in the mechanical old fashioned hard disk (I think it's ok to say its old fashioned now). But Solid State technology within about an year has reached 128 GB. If you to the calculations by the end of the year 2008 we should be able see 1 TB Solid State disks. Awesome, but unfortunately the technology is bit too expensive. Anyways no doubt that the price will come down in the near future.
