One area where the "nvme vs ufs 3.1 speed" comparison gets complicated is heat.
A typical PCIe 4.0 NVMe drive hits sequential read. UFS 3.1 tops out around 2,100 MB/s – faster than SATA SSDs, but less than half of NVMe. nvme vs ufs 3.1 speed
UFS 3.1 is a memory chip combined with a controller, soldered directly to the motherboard. It uses a serial interface and supports full-duplex communication (read and write simultaneously). It is optimized for low power consumption and small physical footprints. The command queue depth is relatively shallow (32 commands), which is fine for a phone, but a bottleneck for a server.
