=== '''SATA (model: IM2S3334 - 512GCTB4)''' ===

The M.2_B-KEY interface of the ASR-A501 supports two types of signals, and the specific type depends on the configuration you have purchased. One is the PCIE signal, and the other is the SATA signal. To test the M.2_B-KEY SATA signal, can use the SATA disk (model: IM2S3334 - 512GCTB4).
