Tech you'll be interested in - "hybrid" SSD drives [Purp]

SSD'ish performance at rotating media prices. $120 for a 1T laptop drive.

Q: What's SSD? (for those who don't already know)
A: (S)olid (S)tate (D)rive. i.e. no rotating platters. Fast/expensive.

Q: What's a "hybrid" SSD drive?
A: Its traditional rotating media (i.e. cheap), BUT it adds a big glob of solid state memory between the drive and the computer, and has onboard firmware that "learns" over time what the most common data being accessed is and stashes that most frequently used stuff in the glob of solid state memory memory for faster access.

Q: How is this different than traditional cache memory found on rotating hard disks?
A: Its persistent. It doesn't go away when powered off. This is why the firmware can "learn" over time and adapt to whatever your usage profile is.

If you're looking for cheap performance, this hybrid SSD stuff looks pretty good.
