Quick Answer
For B660, the best 1TB Gen 4 NVMe is the drive that matches the real M.2 slot speed, cooling, and workload. Use WD Black SN850X for Gen 4 value or Crucial T700 for a real Gen 5 slot as the concrete reference point, with a cautious SA price band of R1,100 to R2,000. The useful target is capacity, TLC NAND, and board slot support in the right order, backed by local warranty support and parts that fit the rest of the setup.
What To Check First
Start with the real job this product must do. Read the motherboard storage table before buying. CPU-connected M.2 slots usually get the cleanest bandwidth, while chipset slots can share lanes with SATA, Wi-Fi, or expansion cards. Check the monitor refresh rate, desk space, cable route, motherboard slot, or control layout before comparing extras. For South African buyers, a clear warranty path and stock availability matter because a technically stronger option is less useful if replacement support is vague.
SA Buyer Shortlist
A sensible shortlist has one value option, one balanced option, and one premium option. Keep the value option near the lower end of R1,100 to R2,000, then spend more only when the spec gain is visible in daily use. A 60 fps story-game setup, a 144 fps esports setup, and a storage-heavy editing PC need different priorities, so match the part to the actual workload.
Mistakes To Avoid
Avoid paying for bandwidth the board cannot expose, and avoid filling an SSD to the last few gigabytes. Game updates need workspace, and Gen 5 drives need real cooling in Pretoria, Durban, or any warm gaming room. Do not buy from a headline spec alone. Confirm clearance, connection type, power or lane requirements, and whether the product solves the problem in the title. If the same money would fix a weak monitor, poor headset, cramped case, or too-small SSD, fix that bottleneck first.
FAQ
Should I buy this NVMe for B660?
Yes, if it matches the target above and does not create a new fit problem. Keep the decision tied to frame rate, comfort, capacity, or input latency instead of the most expensive label.
What should I budget for 1TB?
The practical range is R1,100 to R2,000, but live stock can move. Treat that as a broad buying band, then compare the exact local product page before ordering.
What is the local compatibility check?
Check the exact model, warranty route, return process, and compatibility with your PC. Also confirm the one spec you will feel every day: fps stability, 2.4GHz latency, M.2 slot speed, or controller comfort.
Practical check
Check M.2_1 and M.2_2 lane notes in the board manual, then choose capacity and NAND before peak MB s.
