Problem: I am a video editor upgrading my computer storage to handle high-bitrate footage, and my motherboard layout is shown in the screenshot. I have a high-performance PCIe 4.0 NVMe SSD with a rated sequential read speed of 7,000 MB/s, and the M2_1 slot is already occupied by the system drive. If I install this new drive in the slot marked M2_3 for easier cable routing, based on the motherboard's official technical specifications and PCIe theoretical transfer rates, approximately how much performance (in GB/s) will I lose in sequential reads compared to its rated speed? (Please estimate based on general theoretical bandwidth limits and round the final result to the nearest integer.)
Answer: 3
