Silicon Power Ace A55 Spec and Price in Spain

Name: Silicon Power Ace A55
Brand: Silicon Power

SATA1TB2.5-inch560 MB/s read

The Ace A55 is the smaller and more basic of Silicon Power's two drives: a 1TB SATA model rated for 560/530 MB/s, in line with other SATA drives in this lineup, but its 240TB TBW rating is the lowest endurance figure of any drive listed, and its 3-year warranty ties the BarraCuda Q5 for the shortest coverage. That combination points to light everyday use — web browsing, document work, general storage — rather than heavy write workloads or long-term archival duty. Compared to the PCIe 4.0 UD90 from the same brand, it's a straightforward SATA upgrade at half the capacity, without the NVMe throughput or the higher endurance rating its sibling carries.

Tied 87th of 106 models in the SSD catalog on Sequential read — 8 models share this figure. Tied 89th of 106 models in the SSD catalog on Sequential write — 4 models share this figure.

What owners and reviewers say

Summarised from 2 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

Affordable and performs well for gaming and everyday tasks, with good-quality internals in a solid metal casing.
Held a constant real-world transfer rate regardless of file size.
Owners consider it a cheap, high-capacity SATA drive, often as a low-cost upgrade for an older laptop or console.
This revision carries a DRAM cache, which owners say clearly improves on the SLC-cache variant of the same line.
Real-world load times are reported to be on par with more expensive SSDs.

Commonly criticised

Lags behind other drives in the same price range.
Its cache design brings drawbacks, including lower overall speed.
One owner reported the drive failing after roughly eighteen months of light use.
Owners note the warranty is shorter than some competing lines.
