Review on Ableconn PEXM2-130 Dual PCIe NVMe M.2 SSDs Carrier Adapter Card (ASMedia ASM2824 Switch) - High-Speed 2X M.2 NGFF PCIe NVMe SSD Support for Mac & PC (PCIe x8, Non-Bifurcation Motherboard) by Carnell Bollwitt

Ableconn PEXM2-130 Dual PCIe NVMe M.2 SSDs Carrier Adapter Card is easy to install and works as described in relation to RAID. However, sequential read/write performance from NVMe cards is poor at best. I'm not getting the actual drive speed for PCIe 3.0 as you can see in the test where the max read/write speed was around 1.7 KMB/s with PEXM2-130 and 3.5 KMB/s without PEXM2-. 130. This has been observed on both the Samsung SSD 970 Pro and 980 Pro. Correction: After additional troubleshooting, I found that the problem was in the junction. Although my motherboard supports the fanout required to maximize read/write speeds, it was only supported in my PCIe 2 slot and not the PCI 3 slot. After the slots were moved, the throughput of this card was great. rating changed.
