よくある質問（FAQ）
Q1: Enterprise PCIe Gen 5 NVMe SSDは自作PCで使える？ A: 物理 PCIe Gen 5 connection compatible (M.2 / U.2 adapter) で動作可能 but Consumer Motherboard PCIe Gen 5 lanes limited (typically only x16 GPU slot + x4 M.2 slot = 1 NVMe Gen 5 slot) + Cost $0.10-$0.15/GB はConsumer Gen 5 SSD ($0.08-$0.12/GB) より高価・Enterprise endurance / NAND quality / Power profile / Form factor は Consumer use case overkill・Consumer use case はSamsung 990 EVO Plus / Corsair MP700 Pro等のConsumer Gen 5 NVMe推奨。
Q2: 232-layer NAND の意義は？ A: NAND vertical stacking layer数 (NAND ストレージ密度指標・1 cell area で多 vertical layer = density per chip area) ・232-layer (Micron 2022 world-first) → 同area で more capacity → Cost reduction per GB + Production yield improvement・Industry advance (Samsung 236-layer V8 + SK Hynix 238-layer / Kioxia 218-layer等の Big-Three Top-3 NAND density race進行中・2026年300+ layer予想)。
Q3: U.2 vs E1.S vs E3.S form factor 違い？ A: U.2 (2.5" 15mm thickness・Standard 2.5" SSD form factor・Hot-pluggable Server) ・E1.S (EDSFF・15mm/25mm thickness・Hot-pluggable Dense Server向け・Higher density per rack) ・E3.S (EDSFF Premium・7.5mm/16.8mm thickness・Hyperscale Density)・新しい順 (E3.S 2024年Hyperscaler主流移行 + E1.S Mid-density・U.2 legacy)・Customer Server design alignment必要。
