The Sandisk Ultra Plus has an above average consumer performance profile and is available at a fantastic price. It's one of the cheapest SSD's we have reviewed and we like it a lot. With a real world speed of 488.1 MB/s and an AS-SSD Total score of 910 points, the Ultra Plus is able to handle consumer workloads reasonably well and enterprise workloads just below average. The slightly below average server performance is primarily due to the Ultra's deep queue 4k write speed which clocked in at just 165 MB/s, considerably below the group average of 241 MB/s. Given that this drive is only a few months old, there is a good chance that its prices will drop even further which would make it an even better value consumer proposition than it already is. [Apr '13 SSDrivePro]

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. [Feb '14 SSDrivePro]
