Worth knowing

The T705 is nearly 2x faster than the FireCuda 530 in sequential reads — but only PCIe 5.0 motherboards unlock that potential.
The FireCuda 530 costs significantly less per TB, making it the smarter buy for most current-gen gaming PCs.
Both drives carry a 5-year warranty, so longevity isn't a differentiator here.
The T705 without a heatsink can throttle aggressively — thermal management is a real concern on this drive.
FireCuda 530 is PS5-compatible, giving it bonus points for console storage expanders.

The Crucial T705 is so fast it can read the entire uncompressed script of every Lord of the Rings film in under a second — yet most games won't even notice the difference over the FireCuda 530.
