FireCuda 520 1TB
A historically significant drive: the FireCuda 520 was among the first PCIe 4.0 consumer SSDs ever released, debuting alongside AMD's X570 platform in 2019. Powered by Phison's first-generation E16 PCIe 4.0 controller, it pushed sequential read speeds to 5,000 MB/s — nearly double PCIe 3.0 flagship drives at the time.
