We can see from our tests that the Intel 330 Series 120 GB and the Kingston HyperX 3K 120 GB are fairly evenly matched in terms of performance, as there were no tests in which one significantly outperformed the other.
From the comparison table in the Introduction to this review, we can see that the only difference in hardware between the two drives is the memory employed in each. Even though both use Intel 25 nm NAND, Intel has used eight 16 GB chips in the 330 Series and Kingston has used sixteen 8 GB chips in the HyperX 3K.
Both drives feature the very popular SandForce SF-2281 controller, which supports up to eight channels of memory. As there are only eight memory channels available, the performance of the Intel 330 Series isn’t disadvantaged by the lower number of memory chips.
In fact, in most of our tests, the Intel 330 Series showed slightly better performance than the Kingston HyperX 3K. This could be a result of superior firmware or the slightly different memory chips used.
Considering that the two drives cost exactly the same amount, we would recommend the Intel 330 Series over the Kingston HyperX 3K, as it offers slightly better performance.
However, for those users who are planning to upgrade an existing system with a solid state drive, we would be inclined to recommend the Kingston HyperX 3K Upgrade Bundle Version, because it makes the upgrade process very simple. This version of the HyperX 3K would be especially well-suited to those users who lack technical know-how.
