Seagate FireCuda 530R 1000GB

The Seagate FireCuda 530R is a refreshed iteration of the FireCuda 530 series that maximizes PCIe 4.0 bandwidth using the Phison PS5018-E18 controller. It pairs high-density 3D TLC NAND flash with a dedicated DDR4 DRAM cache to provide low latency and sustained throughput for heavy sequential transfers. The "R" designation denotes a hardware revision intended to improve supply chain availability and slightly push peak sequential read speeds to the interface limit. The drive emphasizes high write endurance and is positioned for workstation use cases and enthusiast gaming.

Key Specifications
