DDR4: legacy squeeze
DDR4 became expensive because suppliers cut or redirected legacy output while buyers panic-restocked before EOL and allocation issues. In spot markets, DDR4 inverted the usual value logic and often traded above DDR5.
DDR4 became expensive because suppliers cut or redirected legacy output while buyers panic-restocked before EOL and allocation issues. In spot markets, DDR4 inverted the usual value logic and often traded above DDR5.
DDR5 rose sharply as server RDIMMs, HBM-adjacent capacity, and AI infrastructure pulled supply away from normal PC channels. The jump accelerated hard from late 2025 into Q1/Q2 2026.
NAND pressure came from enterprise SSD demand, AI storage build-outs, cloud buyers locking supply, and suppliers prioritizing high-margin data-center products over consumer/client SSDs.

ChatGPT in late 2022, GPT-4 in 2023, and GPT-4o-style multimodal tools in 2024 made AI a normal workflow. That pulled enterprise demand up first, then consumer and SME demand followed.
Developers, creators, and SMEs started running local LLMs, RAG tools, image generation, embeddings, and agent stacks. 32GB became tight; 64GB and 128GB builds became less exotic.
Your take is right: model files pile up fast. A quantized 7B model can be around 4GB, 13B can be several GB more, and 70B-class models or image/video checkpoints can turn 1TB into “temporary storage” very quickly.
More game installs, 4K video, phone backups, Steam libraries, AI art assets, and creator caches push normal users toward bigger SSDs even before they touch local models.
Small teams now keep local datasets, meeting recordings, vector indexes, Docker images, dev VMs, and backup copies. That turns “nice to have” RAM and SSD upgrades into operational requirements.
Singapore shelves move in waves: old stock can look cheap, official/warranty stock can look brutal, and spot-price shocks arrive unevenly through distributors. Hence the range chart.
SG chart methodology: June 2026 anchors use live Singapore-facing listings; earlier bands are estimates from CNA/Sim Lim reporting, SG pricing commentary, and global retail movements. Use it for direction and magnitude, not exact shop quotes. June anchors found June 12, 2026: Shopee SG DDR4 16GB listings around S$78.73-S$129, with local-commentary DDR4 16GB 3200 references around S$180-S$215 during the early-2026 squeeze; Lazada SG DDR5 16GB listing around S$115.90; CR Group Crucial DDR5 16GB listing S$422; Lazada SG 1TB NVMe listing around S$89.09; Shopee SG Samsung 980 range around S$114.68; Challenger Kioxia Exceria Plus G4 1TB listing S$341; Vii PC Kingston NV3 1TB/2TB/4TB listing from S$257. OpenAI launched ChatGPT publicly on November 30, 2022; GPT-4 arrived in March 2023; GPT-4o made multimodal AI mainstream in May 2024.
