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 120GB Kingston HyperX 3K is nearly two years old, several generations of SSD have passed since its original release. Better 120GB SSDs have more NAND modules than the old HyperX and are able to write faster than the peak 234 Mb/s achieved by the HyperX 3K. The HyperX 3K also has a Sandforce 2281 controller which is unable to write compressed data as well as its more recent competition. All that said the HyperX still has an effective speed of 367 MBps which is respectable and far faster than even the best mechanical drive. With peak 4K read/write speeds of 33/110 MB/s the HyperX 3K also has competent small file performance. To summarize as a current value proposition the HyperX 3K struggles, simply because the likes of Samsung and OCZ have innovated and moved forward in the two years since the HyperX 3K was released.
