The Risky Solid-State Drive - Columns by PC Magazine  

The Risky Solid-State Drive - Columns by PC Magazine:

Then there is the technology I've harped on over the past five or six years: the HHD, or the hybrid hard disk. When the idea for the HHD was hatched, it was intended to solve all sorts of problems. Half spinning platter and half flash memory, an HHD would increase throughput and make the hard disk more powerful than ever…somehow. I actually sat through a day of presentations outlining how this device would revolutionize the mass-storage industry. It was all ready to go and, as one guy put it, make Vista so hot that people would flock to it. You see, Vista was optimized for this new drive. How soon they forget.

My thought of how a true hybrid hard drive was a little different.

You have a large RAM drive to act as a buffer. Next would be the standard hard drive, which would at least in the beginning, save everything to it. Stuff that was read often, but not changed much would then be gradually moved to the flash memory, because of the finite number of writes that it has. The RAM would be used for speed purposes. Defragmentation and stuff like that would actually be done on the drive itself, and not relegated to the operating system.

That's why I look on SSD drives myself with a lot of disdain.
