That is not very specific, a consumer PC would be fine with a 750 Evo also, maybe two of them in raid 0 for twice the sequential read & write speed. I believe for most consumers, having more SSD storage per $ is more important.
a 750 evo is a sata drive, a 950 is an nvme drive. completely different technology. if my laptop has an nvme slot why would i buy a sata drive. 2 750s is not faster than 1 950
