The Seagate FireCuda 120 is a solid-state drive in the 2.5" form factor, launched in 2019. It is available in capacities ranging from 500 GB to 4 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Seagate FireCuda 120 interfaces using a SATA 6 Gbps connection. The SSD controller is the PS3112-S12-27 from Phison. Seagate has installed 96-layer TLC NAND flash on the FireCuda 120, the flash chips are made by Toshiba. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The FireCuda 120 is rated for sequential read speeds of up to 560 MB/s and 540 MB/s write; random IO reaches 100K IOPS for read and 90K for writes.
At its launch, the SSD was priced at 190 USD. The warranty length is set to five years, which is an excellent warranty period. Seagate guarantees an endurance rating of 1400 TBW, a good value.

Notes

Drive:

Although Seagate has re-branded the controller as "STXZA01F5578" it is manufactured by Phison and it is the model S12.
This drive could feature a small Dynamic pSLC Cache

Controller:

2 main cores using Cortex-R5 clocked at 666 MHz with CoXProcessor technology (one additional dual-core) Cortex-R5 clocked at a lower clock for better efficience.

NAND Die:

Read latency tR: 58 µs (ABL)
tPROG with ~ 25% Overhead: ~ 750 µs (Avg - 42.7 MB/s per each die)
