Quick Answer

B660 is usually not a good reason to pay extra for Gen 5 NVMe because many boards run M.2 storage at PCIe 4.0 speed. Use WD Black SN850X, Samsung 990 PRO, or Crucial T500 as the concrete reference point, with a cautious SA price band of R2,000 to R3,800. The useful target is Gen 4 TLC performance around 7,000MB/s rather than unused Gen 5 peak speed, 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 R2,000 to R3,800, 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 2TB?

The practical range is R2,000 to R3,800, 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.

TIP

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.
