The 120GB OCZ Vertex 3 is almost 3 years old which makes it twice as old as most of the drives in the group test. With sequential peak and average read/write speeds of 510/157 and 390/130 MB/s the 120GB Vertex 3 has good read speeds but lags the group leaders by 50% at writing. This is explained by its Sandforce 2281 controller which is infamous for stability issues and relatively slow incompressible data write speeds. Small file 4K peak and average read/write speeds clocked in at 31/103 and 23/61 MB/s which matches the group leaders, a superb result considering the Vertex 3's age. Overall the 120GB Vertex 3 has an effective speed of 383 MB/s which is only 16% lower than the group leaders which averaged 444 MB/s. The Vertex is a capable drive let down only by its relatively slow peak sequential write speed of 157 MB/s. [Feb '14 SSDrivePro]
