SanDisk 3.84TB NAS 800 PCIe 5.0 M.2 2280 NVMe SSD: Strengths & Caveats
✔ Advantages
- Exceptional write endurance rating of 7,000 TBW engineered for continuous 24/7 high-write workloads
- Peak sequential transfer rates reaching 14,900 MB/s read and 13,100 MB/s write across PCIe 5.0 x4
- Energy-efficient 6nm Silicon Motion SM2508 controller limits active power draw to 6.6W
- Single-sided M.2 2280 layout guarantees mechanical clearance in compact multi-bay drive sleds
✖ Documented Caveats
- Requires passive heatsinking or directed bay airflow to avoid thermal throttling during sustained transfers
- Sequential throughput is constrained to legacy bus limits when installed in PCIe 3.0 or 4.0 NAS backplanes
Samsung Portable SSD P7 1TB: Strengths & Caveats
✔ Advantages
- Sequential throughput reaching up to 4,000 MB/s read and 3,700 MB/s write over USB4 Gen 3x2
- Chassis drop resistance rated up to 6.6 ft (2 m) for portable durability
- Integrated 256-bit AES hardware encryption with password authentication
- Cross-platform support across Windows, macOS, and Android with Samsung Magician utility
✖ Documented Caveats
