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 '14 SSDrivePro]

The Evo is remarkable in that, like the Sandisk Extreme II, it features a second level cache. For the 250 GB Evo this consists of a 3 GB Turbowrite cache (TWC) which is a block of high speed Flash Memory. When the TWC is exhausted write speeds drop by approximately 50% but that won't often happen under typical consumer workloads. In terms of raw performance, even with its cache, the Evo still isn't the fastest drive. With a real world speed index reading of 439 MB/s the EVO is however, within reach of the two speed leaders (Vector and 850 Pro). At a price point of $130 the Evo is around 30% cheaper making it the best value for money SSDs I have seen in 2014. Comparing the Evo and the Sandisk Ultra Plus shows that the Evo is the winner but the Sandisk may be a viable alternative thanks to its cache-free, and therefore more consistent performance during extended writes. [Aug '14 SSDrivePro]
