I bought an Acer Aspire 5 A515-57-727C Laptop and I need to upgrade it's small 250 GB SSD. I bought an V-NAND SSD 1080 PRO PCIe 4.0 NVMe M2 SSD with 4TB from China. It's speed specs are 7450 MB/s write and 6900 MB/s read. The SSD worked, but using the software CristalDiskMark 8.0.5, the SSD reached only 1620 MB/s of read speed and 736 MB/s of write. The original SSD (Generation 3, installed originally at the Gen 4 slot) is faster than it (4889MB/s read and 2033 MB/s write). This laptop model has any limitation that justify this smaller speed from a Gen 4 compared to a Gen 3? Or the problem would be the bad quality of the SSD M2 I bought?

Thanks!
