Disk Copy Benchmarks
We are using AS SSD’s Copy Benchmark tool to test the duration of file copy for ISO, Program, and Game data. The benchmark outputs the duration in minutes and seconds, and lower is better.
In As SSD’s ISO Copy Benchmark, the Patriot Viper VPR400 RGB 1TB SSD is at the top of the pack, with 0.37 second copy time it matches the CORSAIR Force MP600. The Sabrent Rocket and both MSI SPATIUM SSDs are a bit slower in copy performance according to copying an ISO file in AS SSD.
On the other hand, for copying random program data, which has less of a fixed size and more multiple-sized files, the Patriot Viper VPR400 RGB 1TB SSD is the slowest at 2.87 minutes and seconds. All the other SSDs seem to be faster, and this could be due to the usage of having local DRAM on board all the other SSDs on this graph.
The same is also true for the Game Copy files, the Patriot Viper VPR400 RGB 1TB SSD is on the lower side of performance, but oddly so is the MSI SPATIUM M480 in this AS SSD test. All SSDs are rather close in performance, overall speaking, so this isn’t a large issue for this particular test.
DiskBench
With DiskBench we place a 50GB single file onto the test drive. We copy this file from the test drive to a new folder on the test drive, volume to volume. This tests the performance the drive is able to copy a file from itself to itself as if you were copying files on the same drive. Results are in duration Seconds, lower is better.
Unfortunately, the copy performance seems to be a weak point for the Patriot Viper VPR400 RGB 1TB SSD. Using DiskBench, we copied a 50GB file on the SSD and it took nearly 26 seconds. All the other SSDs were faster here, even the Sabrent Rocket, which is overall slower in many other areas, it was faster by 12%. The fastest drive was the MSI SPATIUM M480 by 34%. This is another example where it may be running out of SLC cache, and having to write out to system DRAM, causing a slight delay, all the other SSDs on this graph have local DRAM.
