Samsung Portable SSD P9 2TB: Strengths & Caveats
✔ Advantages
- Up to 4,000 MB/s sequential read and 3,800 MB/s sequential write speeds over 40 Gbps USB4
- Sustained steady-state write performance maintaining up to 2,000 MB/s during large data transfers
- Ultra-slim 0.33 in (8.3 mm) profile and lightweight 3.39 oz (96 g) drop-resistant chassis
- Hardware-based AES 256-bit encryption with password protection via Samsung Magician
✖ Documented Caveats
- Requires a host system with a dedicated 40 Gbps USB4 port to achieve maximum rated speeds
- Lacks native Thunderbolt support, defaulting to lower bus speeds on non-USB4 host ports
Solidigm D5-P5430 30.72TB E3.S: Strengths & Caveats
✔ Advantages
- Massive 30.72TB capacity in an ultra-compact 7.5mm E3.S EDSFF form factor
- Optimized 8KB indirection unit enhances mixed write handling and mitigates QLC write amplification
- Substantial 31.92 PBW endurance supported by hardware power loss protection and OCP 2.0 telemetry
- Strong sequential read speeds reaching 7,000 MB/s and 934,500 random read IOPS
✖ Documented Caveats
- PCIe 4.0 x4 bus rather than next-generation PCIe 5.0 interface
- Sequential (3,000 MB/s) and random (120K IOPS) write speeds remain lower than enterprise TLC drives
