Final thoughts

The Silicon Power Ace A55 1TB is available for a price of approximately 86 USD or EUR, and it offers a good build quality and an adequate performance. The single memory chip used is made by Intel while the memory controller is made by Silicon Motion. Unfortunately, as is the case with many budget SSDs, the controller has no DRAM cache. Instead, the Silicon Power Ace A55 1TB relies on a SLC cache.

The design of the SSD is simple, the only graphics present on the casing are part of a reflective label at the front of the SSD. In addition, the casing of the Ace A55 is made from solid metal and has two parts.

The performance of the Silicon Power Ace A55 1TB is adequate for its price, however it will lag behind other SSD within the same price range, such as the Crucial BX500. Unfortunately, the usage of an SLC cache has its drawbacks, one being the lower overall speed. However, in the real-world testing, the Ace A55 1TB had a constant speed of 340MB/s in both moving and copying of files, regardless of their size.

In conclusion, the Silicon Power Ace A55 1TB is an affordable SSD that offers a good performance for gaming and daily usage. The internal components are of good quality and the same can be said for the metal made casing.
