Looks like Seagate is taking another crack at hybrid hard drives. The benchmarks show that it performs much better than a regular 7200rpm drive.
Now, I know that it works by moving commonly used files to the 4GB flash memory, but what controls the file movement? Is it done by the hard drive itself, or does it require drivers in the operating system? What I'm basically asking is, how easy will it be to get one of these working on a Linux system?
