Solid-state revolution: in-depth on how SSDs really work
SSDs use a huge grab bag of techniques to make a computer feel "snappy."
Way back in 1997, when dinosaurs roamed the earth and I was working part-time at the local Babbage's for $4.25 an hour, I scraped together enough spare change to purchase a 3Dfx Voodoo-based Diamond Monster 3D video card. The era of 3D acceleration was in its infancy and the Voodoo chipset was the chipset to beat. It all seems a bit silly now, but when I slapped that sucker into my aging Pentium 90 and fired up the new card's pack-in version of MechWarrior 2—which had texture-mapping and visual effects that the original 2D version lacked—my jaw hit the floor. I couldn't wait to speed-dial my buddy Matt and tell him that his much-faster Pentium 166 no longer brought all the polygons to the yard.
That video card was the most important PC upgrade I ever made, sparking a total change in my perception of what computers could do. I didn't think I would ever again experience something as significant as that one single upgrade—until the first time I booted up a laptop with a solid-state drive (SSD) in it. Much like that first glimpse of a texture-mapped MechWarrior 2, that first fast boot signaled a sea change in how I thought and felt about computers.
The introduction of 3D graphics changed our perceptions of computing not because it made colors brighter or virtual worlds prettier—though it did those things and they are awesome—but because it made a smoothly responsive 30 and 60 frames per second gaming experience a standard. Solid-state drives have a similar effect. They're faster than spinning disk, to be sure, but their most important contribution isn't just that they are faster, but rather that they make the whole computer feel faster. They remove barriers between you and your PC, in effect thinning the glass between you and the things that you're doing with and through your computer.
