+# A simple script to test Synology NAS disk speed with hdparm, dd and fio.
+#
+# How to use:
+#
+# 1. Save synology_disk_benchmark.sh and xfio.conf to your Synology NAS
+# 2. Make it executable: chmod +x synology_disk_benchmark.sh
+# 3. Run: sudo ./synology_disk_benchmark.sh <test_name>
+# 4. A report file <test_name>.md will be created
