Review on RIITOP Dual NVMe PCIe Adapter | M.2 NVMe SSD to PCI-e 3.1 x8/x16 Card | Supports M.2 (M Key) NVMe SSDs 22110/2280/2260/2242/2230 Sizes by Anatoly Yorgason

I rarely write reviews and am not an expert on SSDs but as this product had no reviews I felt it was necessary. I have a non-raid server running on a micro-ITX MB and wanted to add more disks to the device. My SSD cache drive occupied a SATA port and I had an empty x16 PCI slot. This product allowed me to move cache to 2 Samsung 970 Pro NVME 512GB drives, which allowed me to use all SATA ports for hard drives. It worked without any problems. Unraid recognized the 970 Pro and I was able to put the drives in a RAID 1 configuration. I tested this card on my Windows machine before installing it on my non-raid server. The disks were placed in Raid 0 and I ran CrystalDiskMark, see the results in the photo. 3500 MB/s read and write seems impressive to me. It outperformed my Gigabyte 1TB pci4.0 nvme drive on everything but sequential reads. Gigabyte speed has reached 5000 MB/s. I also ran tests on select 970 Pros. Sequential read speeds were the same, but sequential write speeds dropped to 2300 MB/s. Please note I'm new to SSD so take my review for what it is. If nothing else, I can at least confirm that it works on Unraid.
