Gen 4 SSD on Gen 3 slots
Hi, I have a 2018 Mac mini and a Thunderbolt3 NVME SSD enclosure,
I notice that the Gen 4 NVME SSD is getting cheaper and cheaper, I was wondering if one day some Gen 4 NVME SSDs will be cheaper than some of the expensive models of Gen 3 SSD(Samsung 970 Pro for example),
and did anyone test how the speed decrease in Gen3 slot(in my case, a thunderbolt 3 enclosure)
let 5GB/s be the GEN4 SSD read speed, what speed will it be in a GEN3 slot?
will it be the Max speed of gen3 which is about 3.5GB/s, or will it be 2.5GB/s because the bandwidth is half-off?
Did anybody tried and know the real answer?
@yesornofei, Thunderbolt 3 bandwidth throughput is capped at 22Gbps. PCIe 4.0 NVMe drives in a TB3 enclosure work but they don't go faster than this cap.
