The Intel 330 is just under two years old and sports a Sandforce 2281 controller coupled with Intel's own 25nm MLC NAND. This combination typically produces a performance profile that struggles with incompressible data and favours reading over writing. With peak and average sequential read/write speeds of 514/138 and 414/122 the Intel 330 is unable to compete in today's market and falls over 50% short of the group leaders which manage peak sequential read/write speeds in the 500/300 MB/s region. Small file 4K peak and average speeds are better and clocked in at 32/89 and 24/63 MB/s which is 10% below the group leaders. Overall the 330 has an effective speed of 370 MB/s which makes it one of the slowest 128GB SSDs I have seen to date. [Feb '14SSDrivePro]
The Intel 520 Series was Intel's first SSD to feature a Sandforce 2281 controller. This controller has powered countless SSDs over the last three years but is now dated and is known to be limited in the area of incompressible write speed. The 120GB Intel 520 scored peak and average sequential read/write speeds of 514/157 and 421/133. These read speeds are good but the peak write of 157 MB/s lags the group leaders average of 313 MB/s by nearly 100%. This relative inability to write lowers the 520's overall effective speed to 403 MB/s or 15% lower than the 459 MB/s achieved by the group leaders. At two years of age the Intel 520 can no longer compete with newer drives, there is far better value available amongst the group leaders. [Feb '14SSDrivePro]
