As a follow-up to our previous SSD coverage, today we will be looking at four popular mainstream SSD offerings which include the A-Data S592 128GB, Corsair P Series 128GB, OCZ Agility 120GB and the OCZ Vertex Turbo 120GB.

Although all these products are MLC flash-based and target the consumer enthusiast market, they do vary in price, on-board controllers, memory chips, and cache sizes, which should make for some very interesting results.

With dozens of manufacturers now offering some kind of solid state drive, you should know there are only a handful of them you should concern yourself with. 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 remains the superior performer when it comes to small data writes, the Samsung and Indilinx controllers are worthy alternatives.
