Test Setup
Testing was accomplished on a blank formatted card. I also used a Lexar Multi-Card 2-in-1 USB 3.1 Reader for maximum potential. Our test setup consists of the following hardware:
| CPU | AMD Ryzen 7 3700X (Matisse) |
| Cooling | Gigabyte Aorus Liquid Cooler 240 |
| Motherboard | Gigabyte B550 Aorus Pro |
| Ram | Patriot Viper Steel RGB Series DDR4 32GB (2 x 16GB) 3600MHz |
| HDD | Samsung 960 EVO 250GB PCIE M.2 SSD |
| PSU | Antec Signature Series 1000W |
| VGA card | Zotac Twin Edge 3070 |
| OS | Windows 10 |
I also used the the USB 3.2 port on the motherboard just to be sure I wasn’t creating any bottlenecks in the controllers. On a side not I did test a few passes using the front I/O 3.0 ports and had readings that were basically the same.
Performance
Just as a quick reminder of the advertised specifications from Patriot. Sequential read 95MB/s
ATTO Disk Benchmark v4.01
The ATTO Disk Benchmark application was designed to measure your storage systems performance with transfer sizes and test lengths for reads and write speeds. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously.
