Performance
Performance has been tested on the latest AMD Ryzen platform, which contains the R7 3700X processor and ASRock X570 Extreme4 motherboard.
All tests were performed in Windows 10 Pro x64 with the latest updates. There is nothing unusual in our setup so that readers can compare results to their computers.
Let’s begin with the ATTO Disk Benchmark, which is one of the most popular applications designed to measure storage bandwidth.
The latest version of ATTO is showing lower than expected results, but it’s typical. The older version of ATTO would show declared 560/530 MB/s, but since the market is moving forward, then we are too.
CrystalDiskMark is more interesting as we can see how the A55 performs random operations.
The maximum read bandwidth already looks as high as it should. 552.6MB/s can also be a limit of the bus in this case as every test reaches about the same bandwidth. More interesting are random operations. The 4K Q1T1 test is pretty high for a SATA drive. We were able to reach 38MB/s what we usually see on PCIe drives.
Let’s see how the A55 performs in PCMark series benchmarks, which are simulating real-world workload.
PCMark 8 is one of the most important benchmarks as it shows performance in popular applications and less demanding games. Our result is quite high for a SATA drive. We can’t compare it to PCIe series drives, but it’s respectable.
The same, PCMark 10 result looks well. We are still gathering results to be able to compare drives better in this new benchmark, but our readers can see what results we are achieving.
In the end, Anvil’s Storage Utilities. It’s a benchmark that usually shows lower bandwidth than expected. Results in this benchmark are not the best, but let’s say above average for a SATA drive.
I’m sure that all who decide on the A55 drive will be satisfied with its performance. It’s not the fastest drive around but offers high performance and causes no problems with stability or overheating like some competitive products. Users who demand higher performance have to pick one of the M.2 PCIe drives as on the SATA bus, there is nothing much better.
