Performance
The performance has been tested on the AMD Ryzen platform, which contains the Ryzen 9 3900X CPU, ASUS Crosshair VIII Impact motherboard, Ballistix Elite 16GB DDR4-4000 memory kit, and Samsung 970 EVO M.2 SSD with installed Win10 Pro x64.
There will be an internal test with connection via SATA port and an external through USB 3.0/3.1 so all can see what the KC600 has to offer.
Let’s start with the ATTO Disk Benchmark.
Sequential bandwidth tests are pretty good. If we used an earlier ATTO version, then we could see a bit higher results. The latest ATTO version shows over 522MB/s sequential read and 445MB/s write. The bandwidth is pretty consistent what tells us a lot about drives stability and performance.
Better results are in CrystalDiskMark, which usually is a more demanding benchmark. We can see up to declared 550MB/s and write up to 470MB/s, a couple of MB/s more or less depends on the run. However, also here, results are not much different regardless of test file size.
Recently released storage tests in PCMark 10 are a mixed load environment that is closer to a typical daily load. Both results are not bad but could be better. On the other hand, there were not many drives in our redaction since new tests were released, so it’s hard to compare these results directly to the competition.
Results that are below were made using a USB enclosure delivered with the KC600. USB 3.0/3.1 controllers are usually limited to about 400-450MB/s maximum bandwidth, so there is our expected maximum speed of the drive.
The drive via the USB 3.0/3.1 port can make close to maximum expected bandwidth, so about 445MB/s. Random operations are also quick, with up to 27MB/s read in low queue 4KiB tests in CrystalDiskMark.
Results in PCMark 10 are significantly lower via the USB connector, but it was expected. Overall performance, even using a USB controller, is quite good and should satisfy most users.
The KC600 is a significant upgrade from an HDD or older generation SSD. I’m sure that all who decide on this product won’t be disappointed.
