PCIe Gen 4 and Gen 5 NVMe SSDs tested for sequential read/write speeds, DirectStorage game loading, and thermal throttling in Indian summers.
Game engines rely on random 4K read speeds rather than peak sequential multi-gigabyte transfers. A high-quality Gen 4 SSD (such as the WD Black SN770 or Samsung 980 Pro) offering 5000MB/s–7000MB/s read speeds provides 98% of the real DirectStorage loading benefit at a fraction of the cost and heat.
Build an Optimized Gaming PCHigh-speed Gen 4 and Gen 5 NVMe SSDs run notoriously hot. In a 38°C Indian room, an un-heatsinked M.2 drive will quickly cross 70°C under sustained writes, causing thermal throttling down to HDD speeds. ALWAYS install your NVMe drive under your motherboard's metal heatsink.
Expert advice for Indian builders and PC gamers.
Microsoft DirectStorage bypasses the CPU and streams compressed game assets directly from your NVMe SSD into GPU VRAM. It eliminates loading screens and texture pop-in in supported games like Forspoken, Ratchet & Clank, and upcoming Unreal Engine 5 titles.
Yes, modern DRAM-less NVMe SSDs use HMB (Host Memory Buffer) to borrow a tiny fraction of your system RAM for caching, delivering virtually identical gaming load times to expensive DRAM drives while saving ₹1,500–₹3,000.
