The behavior of the jetson-agx-orin varies depending on the SSD used. The jetson-agx-orin is booted with SSD using Jetpack 5.1.1. While normally using PCIe Gen3 x4 (PCIe SSD 112S), upon switching to a different SSD with PCIe Gen4 x4 (PCIe SSD 240S), the operation slowed down. Considering the occurrence of the following error on the slower operation, there was a suspicion of incompatibility with PCIe Gen4 x4. However, when another PCIe Gen4 x4 SSD (SSD-CK1.0N4PLG3N) was used, the operation remained the same as before. Could it be that in Jetpack 5.1.1, the compatibility issue with SSD types causes the slowdown in operation?
