🔄 Why Upgradability Matters in 2025
Before diving into models, here’s why upgradability is crucial today:
-
New games are more demanding – With ray tracing, 4K textures, and larger worlds, hardware requirements grow fast.
-
AI workloads are rising – Generative tools, upscaling, and real-time enhancement benefit from more RAM and storage.
-
SSD and RAM upgrades are cost-effective – Instead of replacing your entire laptop, simple upgrades can boost performance dramatically.
-
Graphics drivers and tech evolve quickly – Future-proof laptops let you stay compatible longer without a full hardware refresh.

✅ User-accessible RAM and SSD slots
✅ Dual-channel RAM configuration
✅ Expandable storage (dual SSD bays or 2TB+ capacity)
✅ Accessible internals (via a removable bottom panel)
