newunraidusers Posted February 6, 2020 Share Posted February 6, 2020 (edited) Im attempting to run a benchmark but scores aren't going through because my drive is being ram cached. https://www.userbenchmark.com/UserRun/24416291 I tried disabling it in windows but I still get the issue, also I can tell it still works because im getting over 1000mbs read 2000mbs write sequential speeds on an SSD (It is not an M.2 or nvme btw and realistic speeds i get is around 500mbs both read and write) How can i fix this issue or disable the feature on unraid?
