Test Setup
Testing was accomplished on a blank formatted card. I also used the Lexar Multi-Card 2-in-1 USB 3.1 REV. B 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 DDR4 3600MHz 64GB (32×2) |
| HDD | XPG 256GB PCIE M.2 SSD |
| PSU | Antec Signature Series 1000W |
| OS | Windows 10 |
“Speeds based on internal testing. Actual performance may vary. Read/write speed full performance achieved only when paired with Lexar Multi-Card 2-in-1 USB 3.1 Reader or Lexar Professional Multi-Card 3-in-1 USB 3.1 Reader marked with Rev B, or visit the Lexar website or contact Lexar Technical Support to update reader firmware.”
I will be testing out of the box performance. 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 Lexar. Sequential read 160MB/s and sequential write 120 MB/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. You can test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives.
ATTO Disk Benchmark Features:
- Transfer sizes from 512KB to 8MB
- Transfer lengths from 64KB to 2GB
- Support for overlapped I/O Supports a variety of queue depths
- I/O comparisons with various test patterns
- Timed mode allows continuous testing
- Non-destructive performance measurement on formatted drives.
Results: Max Sequential read 152.60MB/s and sequential write 124.27MB/s
Crystal Disk Mark 7.0
CrystalDiskMark is designed to quickly test the performance of your hard drives. Currently, the program allows to measure sequential and random read/write speeds.
CrystalDiskMark Features:
- Measure sequential reads/writes speed
- Measure random 512KB, 4KB, 4KB (Queue Depth=32) reads/writes speed
- Select test data (Random, 0Fill, 1Fill)
- Theme support
- Multi-Language support
Results: Max Sequential read 159.38MB/s and sequential write 128.03MB/s
AIDA64 Disk Benchmark
Results: Max Linear read 159.8MB/s and sequential write 123.4MB/s
There we have it! The 1066x SDXC brought to us by Lexar! Let us cover a few final thoughts and conclusion of our review.
