To fully utilise the speeds (~7,000/5,400 MB/s), your motherboard/system must support PCIe 4.0. If you only have PCIe 3.0, you’ll see lower performance.
High-speed SSDs like this can generate heat; ensure your M.2 slot has good cooling or heatsink support.
Even though specs are high, real-world gains over slightly slower SSDs may be less dramatic for everyday tasks (loading times, etc.) — but in heavy workloads it matters. For example, in benchmark tests for this exact model: read ~7,000 MB/s, write ~5,678 MB/s.

Check local price and availability in Algeria (import fees, shipping etc). Often high-performance SSDs cost more relative to markets in Europe/US.
