Samsung Magician Low performance
When I measured my device’s performance using Samsung Magician, it is slower than the specification. What should I do?
1. If you have a SATA SSD, make sure that it is correctly connected to a SATA3 port. You can check this via the Interface menu on the Magician Home screen.
2. If you have an NVMe SSD, check whether both the NVMe Interface and PCIe® 3.0, x4 Lane are supported and correctly connected. You can check this via the Interface menu on the Magician Home screen.
3. With some mainboards, a NVMe SSD connected to a PCle slot tends to perform better than when connected to an M.2 slot. We recommend you to connect NVMe SSDs to PCIe® slots.
4. When the temperature of the system is high, the measured speed may be slow. This is only a temporary phenomenon caused by your Samsung SSD’s Dynamic Thermal Guard feature, which is provided with Samsung SSD’s firmware and may be engaged to protect the Samsung SSD in some systems with poor thermal management capabilities.
5. If you are running a program that may affect system performance, please close the program and measure speed again.
6. Change the Power Management option to High Performance and measure speed again.
7. Performance results may vary depending on measurement conditions including, without limitation, the foregoing cases numbered from 1 to 6.
