The Seagate Firecuda 530 is a solid-state drive in the M.2 2280 form factor, launched in 2023. It is available in capacities ranging from 500 GB to 4 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Seagate Firecuda 530 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the PS5018-E18-41 from Phison, a DRAM cache chip is available. Seagate has installed 176-layer TLC NAND flash on the Firecuda 530, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The cache is sized at 225 GB, once it is full, writes complete at 3850 MB/s. Copying data out of the SLC cache (folding) completes at 1600 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The Firecuda 530 is rated for sequential read speeds of up to 7,300 MB/s and 6,900 MB/s write; random IO reaches 1000K IOPS for read and 1000K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Seagate guarantees an endurance rating of 2550 TBW, a good value.
