PC's from ~7 years ago operated in the 4.8-6.4GT/s (Giga-transfers/s) and are now up to 10.4GT/s in current processors. That gives a comparison point to PCIe's 2.5 - 8 GT/s. That's likely to give around 2GB/s (I get up to a bit over 1GB/s with HW RAID using 7200RPM disks using a 3Gb/s bus speed (older generation computer). The random perf differences of the PCIe cf. my RAID, would likely be a few-to-several times greater than the linear.
So much faster (and maybe replacing conventional HD's for PC's, but w/RAIDs still used for capacity -- at least for a while.
My new home system has 2TB of NVMe storage and no HDD or SSD storage each NVMe is benchmarking at speeds of 3100GB/sec (read) and 2300GB/sec (write) That's 'Bytes', not 'bits' as typically used when benchmarking SATA/SAS drives. I could set them up as a RAID if I wished (AMD Bios' support it at least) So I don't think it's fair to categorise things the way you have. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
