| ATTODisk Write | 432 MB/s |
| PCMark 10 Bandwidth | 183 MB/s |
In CrystalDiskMark, the Silicon Power Ace 55 comes out with 556 MB/s and 457 MB/s in sequential reading and writing In ATTO Disk we see rates above 552 MB/s in reading and 432 MB/s in writing.
During daily use, file transfers with the Ace 55 remains stable at around 400 MB/s, which is good. The overall performance is almost the same as specified by Silicon Power but there were some inconsistencies in the write speeds.
In our Final Fantasy XIV StormBlood test, a benchmark that simulates game load time, the Ace 55 came out with a load time of 18.70 seconds.
With regards to temperature, the Ace 55 never exceeded 45C even at maximum performance during our tests.
Software
Silicon Power’s SSD storage software is known as SP Toolbox. The software is fairly basic and offers very few settings except the essentials.
Verdict
The Silicon Power Ace A55 1TB is an entry-level SATA SSD for those looking for a fast and cost-effective secondary storage solution.
This is a good choice if it’s your first upgrade from traditional HDD’s as it is relatively cheap at AED 330 (USD 90) and offers decent performance in addition to the 3-year warranty.
