While it's not quite as fast as its OCZ Vector sibling, OCZ's Vertex 4 is a very speedy SSD. It uses the company's older IndiLinx Everest 2 controller, but contains the same synchronous MLC NAND used in the Vector. The combination proved fast enough for this drive to take fourth place in overall performance.
Samsung 840 Pro (256GB): A screaming-fast SSD
It's always easy to write about the best--in this case, the Samsung 840 Pro with its proprietary MDX controller. Samsung also manufactures the toggle-mode MLC memory found in the 840 Pro, and judging from the results of our tests, the company knows what to do with it. The 840 Pro finished first in overall combined reading and writing. It also placed first in three of our four individual read and write tests.
SanDisk Extreme (240GB): Bang for the buck
SanDisk's Extreme SSD is a study in extremes, at least pricewise. With the 240GB version carrying a $399 suggested retail price, you might dismiss it out of hand. That would be a mistake: We found the drive selling online for a mere $165 (as of December 18, 2012), which lowers the drive's price per gigabyte to just 69 cents--the lowest price in the entire roundup.
