Define faster.
Most of the time, it is the small random I/o latency at queue depth of 1 or 2 which matters.
That is what windows does most of the time.
But, it seems that synthetic benchmarks are what is commonly measured and at max queue depths.
Really not that relevant.
Sequential speed matters some, and a ssd that uses pcie x4 will be some 4x faster in sequential operations than a normal sata drive.
My take is that Samsung pro drives are currently the highest performing and most reliable.
Use a Samsung M.2 960 pro if your motherboard supports it.
Larger capacity drives perform a bit better and have better endurance
The anandtech ssd bench will give you some comparisons
