Why NVMe Gen 4 Is the Sweet Spot for Gaming
PCIe Gen 4 NVMe SSDs deliver sequential read speeds of 4,000 to 7,000 MB/s — numbers that exceed what any current game storage pipeline actually requests. Game load times are determined primarily by random read throughput and file decompression speed, not peak sequential reads. Benchmarks comparing Gen 3 and Gen 4 SSDs in real game load tests show differences of 0.5 to 2 seconds — imperceptible in practice. Gen 4 does matter for DirectStorage as more titles adopt it, allowing GPUs to decompress assets directly from storage with reduced CPU overhead. Gen 3 is still entirely adequate for most gaming in 2025, but Gen 4 is priced so close to Gen 3 in India that there is no reason to buy Gen 3 new. Gen 5 sequential speeds above 10,000 MB/s have zero impact on any existing or announced game — that headroom exists only for large sequential workloads like video editing.
Budget Gen 4 Picks: Crucial P310 and Kingston NV3
For budget-conscious builds, two Gen 4 NVMe drives stand out in India. The Crucial P310 1TB is available at Rs 4,500–5,500 from Vedant and MD Computers, delivering sequential reads up to 7,100 MB/s — the highest in its price class. It is DRAM-less, which means sustained sequential write performance can dip after the SLC cache is exhausted, but for gaming workloads — primarily reads with occasional small writes during saves — this limitation is irrelevant. The Kingston NV3 1TB sits at Rs 4,000–5,000 and offers sequential reads of 6,000 MB/s with a similar DRAM-less design. Both drives are M.2 2280 form factor and require a PCIe Gen 4 M.2 slot for full speed — they fall back to Gen 3 speeds on older boards, which is still functional. For a gaming build where storage is not the primary budget focus, either is an excellent low-cost choice.
Mid-Range: Kingston Fury Renegade 1TB
The Kingston Fury Renegade 1TB at Rs 7,500–9,000 is a meaningful step up. Unlike the budget DRAM-less drives, the Fury Renegade includes a full DRAM cache, which sustains write performance over extended operations — important if you download large game updates, install multiple games simultaneously, or frequently move large files. Random 4K read IOPS on the Fury Renegade reach approximately 1,000,000 IOPS compared to around 500,000–650,000 IOPS on the P310 and NV3. For pure gaming, the IOPS improvement is barely perceptible in load times, but the sustained write stability makes this drive a better daily-use choice for a PC that does more than just game. The 2TB variant at Rs 13,000–16,000 is a strong pick for users who want to keep 15–20 games installed without juggling storage.

DRAM vs DRAM-Less: What It Actually Means
Every NVMe SSD uses a portion of NAND flash as an SLC write cache to boost initial write speeds. Budget DRAM-less drives — like the Crucial P310 and Kingston NV3 — use the host computer's system RAM as a temporary map table via Host Memory Buffer (HMB). This works acceptably for gaming because game installs and updates are bursty operations that fit within the SLC cache window. The problem appears during large sustained writes: once the SLC cache fills, DRAM-less drives can drop to 400–800 MB/s sequential write speeds. Mid-range and premium drives like the Kingston Fury Renegade carry a dedicated DRAM chip that stores the address translation table independently of system RAM, maintaining consistent performance throughout large writes. For a gaming-only PC, DRAM-less is acceptable. For a build used for game development, video editing, or sustained large-file workflows, a DRAM-equipped drive is worth the Rs 2,000–3,500 premium.
Do NOT Buy a PCIe Gen 5 SSD for Gaming
PCIe Gen 5 NVMe SSDs — including the Kingston Fury Renegade G5 1TB at Rs 12,000–15,000 — deliver sequential reads above 12,000 MB/s. For gaming, they are the wrong purchase in 2025. No current game, game engine, or DirectStorage implementation benefits from sequential speeds above 7,000 MB/s. The real-world load time difference between a Gen 4 drive at 7,000 MB/s and a Gen 5 drive at 12,000 MB/s in any tested game is under one second — often unmeasurable. Gen 5 SSDs also run significantly hotter than Gen 4: without an active heatsink or a motherboard with an integrated M.2 thermal solution, they throttle back to Gen 4-equivalent speeds within minutes of sustained load. Save Rs 5,000–7,000 and spend it on the GPU instead.
1TB vs 2TB and Compatibility Checks
A 1TB NVMe SSD is the minimum for a gaming build in 2025. Modern games have grown considerably — Call of Duty Warzone exceeds 100 GB, Hogwarts Legacy uses 85 GB, and RDR2 with updates takes 120 GB. Windows 11 plus drivers occupies 40–60 GB, leaving approximately 900 GB for games on a 1TB drive. If you regularly play ten or more large titles without uninstalling, 2TB is the practical minimum. Before ordering, verify two things: first, check your motherboard's M.2 slot generation — B650 and Z790 boards have at least one PCIe Gen 4 M.2 slot; older B450 boards are limited to Gen 3. Second, confirm the slot is M.2 PCIe and not M.2 SATA — both use the same connector but SATA M.2 is limited to 600 MB/s. All drives in this guide are NVMe and require an NVMe-capable M.2 slot.
Verdict
For most Indian gaming builds in 2025, the Crucial P310 1TB at Rs 4,500–5,500 is the correct budget pick — Gen 4 speeds, reliable performance for gaming, and no unnecessary premium. For builds that go beyond gaming into content creation or heavy multitasking, the Kingston Fury Renegade 1TB at Rs 7,500–9,000 adds DRAM cache and sustained write stability worth paying for. Skip Gen 5 entirely unless you do professional video or 3D work — the Rs 5,000–7,000 saved is better invested in the GPU.
