+# SATA to NVME session

+## Goal
+- Move all data in NTFS partition `/dev/nvme0n1p2` to `/x/sata1/snapshots`.
+- Use partclone and zstd for the best efficiency.

+## Script Review: 0001-transfer.sh
+
+**Purpose:** Creates a compressed backup image of an NTFS partition using partclone and zstd compression.
+
+**Key Components:**
+- **Source:** `/dev/nvme0n1p2` (NTFS partition)
+- **Output:** `/x/sata1/snapshots/nvme-old-1tb.zst` (compressed image)
+- **Transfer Size:** 436G (used for progress monitoring)
+
+**Pipeline:**
+1. `partclone.ntfs -c -s $SOURCE_DISK -o -` - Clones NTFS partition to stdout
+2. `pv -s $TRANSFER_SIZE -pterb` - Monitors progress with visual feedback (progress, time, rate, bytes)
+3. `zstd -T0 -19 -o $OUTPUT_IMAGE_PATH` - Compresses with max compression (level 19) using all CPU threads
+
+**Notes:**
+- Requires `sudo` privileges
+- Uses maximum compression (`-19`) for best space efficiency
+- Multi-threaded compression (`-T0`) for faster processing
+- Progress bar provides real-time feedback during the long-running operation
+
+Let's go.
