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 128GB Vertex 4 has an average score of 90.5% which is the highest we have seen to date for a 120-128GB SSD. We have in excess of 100 UBM samples for the Vertex 4 and they show that the 128GB Vertex 4 performs superbly outside the lab. With peak sequential read/write speeds of 508/391 and averages of 398/325 MB/s the Vertex 4 manages to average around 75% of its peak sequential speeds, a very impressive result. The Vertex 4 was superseded by the OCZ Vertex 450 several months ago. OCZ release new versions with minor tweaks approximately every six months. Comparing the Vertex 450 to the Vertex 4 shows that the move to 20nm flash and a new Indilinx controller has reduced overall performance by around 15%, so the older Vertex 4 is actually faster than its successor.
