FPGA writing to SSD

FPGA A (which is part of an existing system) transmits data using Serial Lite at 24 Gb/s.
This data shall be received by FPGA B (to be designed) and written to an external storage device (SSD or multiple SSDs).
The data volume is in the order of < 10 Terabytes.

I thought of 2 possible approaches:
1. Connect the storage devices directly to FPGA B (using a custom board) and have the FPGA write directly to them. (I assume this will require implementing an NVMe controller in FPGA B).
2. Install FPGA B inside a PC like system where it will communicate via PCIe and do DMA transactions towards the storage devices.

Which of the above approaches offers better performance ?

To keep up with recent high performance NVMe SSD (6 - 7 GB/s sequential write speed), you need 4 lanes PCIe 4 interface. Implementing direct FPGA-to-NVMe interface avoids possible, hard to handle PC software bottlenecks.
