On a modern raid of NVME, you can do several gigs per second - with 20 PCIe Gen3 lanes on a 3400G about 10 GB/s is reasonable, for a theoretical max of 20GB/s.

On a modern raid of NVME, you can do several gigs per second - with 20 PCIe Gen3 lanes on a 3400G about 10 GB/s is reasonable, for a theoretical max of 20GB/s. Assuming your system is very badly configured and you can only do 3 gigs per second, about 400 s, so about 5 minutes, which is not very painful
