A look at SSD performance in Windows Vista
 

We've narrowed our focus to three drives today because the results of our last SSD round-up nicely illustrated the fact that storage controllers (and firmware revisions) largely define SSD performance. Only a handful of different storage controllers are available, with numerous drives based on each. Intel's X25-M, for example, is available not only directly from the chip giant, but also through partner Kingston. Samsung makes its own drives, too, and its latest controller can be found in new models from Corsair and OCZ. Indilinx's SSD silicon may be the most promiscuous of the bunch. The company doesn't sell its own drives, but it has numerous partners, including OCZ, Super Talent, and Patriot, just to name a few.
