The 120GB Seagate 600 is yet another drive that massively underperforms its larger, in this case 240GB, sibling. Looking at the 120GB and 240GB 600's shows that the larger 240GB version has peak speeds that are nearly 50% higher than the smaller 120GB. This increase in speed is down to additional NAND modules on the larger version which allow more parallelization during writes. The 120GB 600 has peak sequential read/write speeds of 508/246 MB/s which is great for reading but terrible for writing. The 600 does have reasonable deep queue performance but that doesn't make up for its relative inability to write. Overall the 120GB Seagate 600 is both slower and more expensive than the group leaders. [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]
