Kingston HyperX 3K 240GB SATA III SSD Review – Better Value With Incredible Performance


Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. Many new SandForce Driven SSD owners who cant wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with incompressible data rather than compressible data used in testing by manufacturers.

The 3K hits almost exactly the mark the original set, despite the 3K PE rated flash and newer firmware. 328MB/s writes with random data is about the best result any SF-powered drive could hope for. 4K QD1 randoms are spectacular as well, especially the 35MB/s 4K random read score.


Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it tests through use of incompressible data which shows us the worse case performance scenario in SSD transfer speeds.  Many enthusiasts prefer benchmarking with AS SSD for their needs.

blankAS SSD results are an average, and 4K scores are generally lower than CrystalDiskMark and AnvilStorage utilities. The composite score of 779 is eclipsed by some newer drives, but the individual scores are competitive.

blankAS-SSD’s file copy test is absolutely stellar. The HyperX 3K handles the test with great scores, and compares extremely well to other both other SandForce drives and other high-end SSDs in general.


You may not see this for long (and its definitely not common) but you get a freebee simply for reading!  Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility.  Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.


Anvil Storage Utilities has a vast array of options, including multiple compression levels, and multi-threaded read and write tests. The 3K’s zero-fill scores in Anvil are excellent as well, showing extremely high random performance, much higher than CrystalDiskMark and AS-SSD. Those two benches use random data by default, but the cause for such higher scores is generally found in the way the bench tests a given parameter.

blankblankAnvil’s read/write IOPS testing was performed. The HyperX pulled down much higher max IOPS than rated by Kingston, though they test with IOmeter. ASU is very similar, and the data here is very easily compressible, but the results are still impressive at 79,460 read IOPS and 91,772 write IOPS as compared to the rated 86,000 read and 60,000 write max IOPS. The difference is likely the compressibility of the data and the testing method but it is still nice to see.

    my kingston sh103s3120g temperature is always at 45C. it’s that ok?i use it in a laptop.
