Seagate FireCuda 530 1000GB

SSD Description

The Seagate FireCuda 530 pairs a Phison PS5018-E18 controller with Micron 176-layer 3D TLC NAND, using a dedicated DDR4 DRAM cache to manage mapping tables and sustain consistent random I/O. The drive is engineered to fully saturate the PCIe 4.0 x4 interface, and Seagate applies custom firmware validation that prioritizes write endurance, resulting in a high Total Bytes Written (TBW) rating. The Phison E18 controller can run hot under sustained workloads, making adequate heatsinking important, and the 1TB model maintains high sustained write speeds even after the pseudo-SLC cache is exhausted.

Key Specifications
