Following on from our previous SSD coverage, today we're going to look at four popular popular SSD offerings including the A-Data S592 128GB, Corsair P-Series 128GB, OCZ Agility 120GB, and OCZ Vertex Turbo 120GB.
Although all of these products are based on MLC flash and are aimed at the consumer market, they vary in price, integrated controllers, memory chips and cache sizes, which should lead to some very interesting results.
With dozens of manufacturers now offering some kind of solid state drive, you should know that there are only a handful of them to look into. MLC drives based on either the Samsung S3C29RBB01-YK40, Indilinx Barefoot, or Intel's own controller are all you should be looking at today. While the Intel controller provides superior performance for small data writes, the Samsung and Indilinx controllers are worth alternatives.
Choosing between an SSD based on the Samsung and Indilinx controllers is no easy task. Overall, we've found drives using the Indilinx controller to be a bit faster, but since performance is almost too close to be called, price usually matters. Since the OCZ Summit (Samsung) is more expensive than the Vertex (Indilinx), we would probably go for the latter.
However, if you add more drives to the mix, it will be interesting to see how the Corsair P-Series (Samsung) stands out from the new OCZ Vertex Turbo SSD. We've also included a reduced entry-level OCZ drive called Agility, which is available for just $ 300 with a capacity of 120GB. A-Data has also sent its new 128GB S592 series SSD based on the Indilinx controller.
