ADATA Swordfish 1Tb use previous bus standard that is undoubtedly slower than PCIe 4.0. The write speed is 1200 Mb/s, that is slower than has most of rivals. The Internal SSD provide possibility to write 540 TBW, that is not much compared to nearest competitors. When everything is weighed in the balance, ADATA Swordfish 1Tb has more cons and our site highly do not recommend to have it.

The ADATA Swordfish has Host Memory Buffer. Which means that the storage uses the host system's random-access memory for its proprietary operations. DRAM makes SSD faster, but also more expensive.

The ADATA Swordfish due to the low density of memory chips can function without further cooling systems. Some motherboards or laptops from the factory has thermal pads above and below the drive for improving productivity during times of high loads.

The ADATA Swordfish has sequential write speed 1200 Mb per second, sequential read speed 1800 Mbps. It works on Realtek RTS5763DL controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The memory type is ADATA 3D TLC.
