Kingston DataTraveler HyperX Predator 512GB USB 3.0 Flash Drive Review


Synthetic & Real World Benchmarks

CrystalDiskMark 3.0.2d x64:

CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.

Crystal Disk Mark

Benchmark Results: CrystalDiskMark showed that we hitting 296MB/s read and 183MB/s write on the sequential test! Not bad considering that the drive is rated at 240MB/s read and 160MB/s write! The 512K and 4K write speeds aren’t that impressive, but this is a USB Flash Drive and not a storage drive!

ATTO v2.47:

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant.. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.


Benchmark Results: The Kingston HyperX Predator 512GB USB 3.0 Flash drive was able to hit 235MB/s read and 73MB/ write speeds in ATTO with the default benchmark settings. The write speeds weren’t that impressive in this benchmark and were far lower than the advertised speed rating.

Check Flash v1.16.2:

Check Flash is a multi-purpose flash drive testing and maintenance tool. This utility allows for error checking, speed tests, and much more.

Check Flash Benchmark Utility

Benchmark Results: Check Flash showed that we averaged 224.95MB/s read and 98.96MB/s write on the speed test. It also didn’t find any errors on the 512GB drive, which is good news.

Real World File Transfer Tests

TeraCopy is a compact program designed to copy and move files at the maximum possible speed and features a timer that works great for review purposes as we can easily show you time differences between different file transfer scenarios. TeraCopy also uses dynamically adjusted buffers to reduce seek times and has asynchronous copy speeds up file transfer between two physical hard drives. Let’s see what the Kingston HyperX Predator 512GB Flash drive can do when moving around a 551MB folder containing 178 images taken at CES 2013 on our Canon PowerShot Elph 320HS digital camera!


The very first test that we ran was to see how long it took to move the 551MB file directory from the SSD on our system to the Flash Drive. The file transfer took 10.8 seconds to complete and averaged 55MB/s transfer speeds writing from the system to the DataTraveler HyperX Predator. ATTO showed 55MB/s write speeds at a number of file sizes, so this real world test confirms those synthetic benchmark results!


The next test we ran was to copy the 551MB directory from the Flash Drive to the desktop of our test machine. This is a test of the read speeds and we noticed that the performance increased a103MB/s and that it took just 5.4 seconds to move the files over.

Not bad performance numbers as you’ll be wanting fast transfer speeds when you have 512GB of data on a Flash drive!
