"On the first page we referred to the Agility 3 240 GB SSD as the 'almost' Vertex because in many ways performance is very similar although not across the board and from a hardware perspective, they are very close in design. Like the Vertex 3, its performance on highly compressible data is the among the best we've seen for a single drive configuration. Even with incompressible data, it keeps pace on the writes but it's simply not as strong in the reads which is likely attributable to the difference in architecture with the Agility 3 using the ONFI 1.0 NAND offering less bandwidth..."
