Corsair's Force Series 3 Solid State Drives have been getting quite a bit of attention. These drives sport the Sandforce SF 2281 Controller and promise speeds up to 550MB/S Read and Write Speeds of 520MB/S. These drives will be out later this month, and look to potentially de-throne the infamous Vertex 3 drives.
These are very well priced. Not mentioned in this piece though.. but the 60GB is $140. Perfect for a boot drive.
I am using the Vertex 3 right now. I boot up in about 10 seconds. I wonder what this drive could do!
