ZhiTai TiPlus7100 512GB

While there are still many details that need optimization and enhancement, the new SSD product composed of new NAND and a new controller is already a very stable product. πŸ‘

PyNVMe3 Test Report of TiPlus7100

Read latency is too high in some workload (>300ms).

10 IOPS 99% (ms) 4K 1QD 99.9% (ms) RW mixed with trim 99.9% (ms)
TiPlus7100 895.650 0.118 372.113
SN770 102.830 0.179 16.043
S50Pro 1.824 0.122 78.861

Sequential read performance is better than competitors. But the time-0 speed is slow.
