## Disk Usage Summary
| Mount | Device | Total | Used | Free | Use% |
|-------|--------|-------|------|------|------|
| / | /dev/nvme0n1p2 | 468G | 411G | 34G | **93%** |
| /boot/efi | /dev/nvme0n1p1 | 511M | 328K | 511M | 1% |
| /home/mw/models | /dev/sda1 | 466G | 28G | 437G | 6% |
## Observations
1. **Primary disk at 93%** - consider cleanup or expansion. Only 34G free on root.
2. **DDR4 not DDR5** - previous `workstation-health.md` incorrectly listed DDR5-3200. Actual: DDR4-2666.
3. **Mixed RAM kits** - 2x Kingston + 2x Samsung modules. Both rated 2666 MT/s, dual-channel active.
4. **GPU aging** - GTX 1050 Ti (2016 architecture) with 4GB VRAM. Adequate for dev work, not for ML.
5. **Samsung 840 EVO quirks** - Known SATA quirks for this older SSD model (non-critical).
6. **BIOS up to date** - F53 from 2025-10-28 is recent.
7. **No ECC memory** - Non-ECC unbuffered DIMMs.
