Buscando la referencia en Google aparece como generación pci 3!... Estoy confundido.** A: Estás en lo correcto. Es generación 3. **Q: will this work with an intel nuc8i7beh?** A: Yes, it is **Q: Will this work in a Thinkpad T480?** A: It works with any Windows 10 or 11 system. **Q: Will this work in Lenovo Thinkpad Yoga 11e ?** A: Just installed this ssd after cloning. The ssd has full 512 GB after some manipulation as the cloning software created a C drive of only 128 GB, as the originally equipped. I needed to create a partition at the far end of the SSD and clone the partition. Then unallocated the partition behind the C drive but ahead of the aforementioned cloned partition. Using extension to combine the C and the unallocated partition gave me a C drive of around 450 GB as there were other partitions allocated for other things. ## Frequently Bought Together - SAMSUNG 512GB M.2 2242 42mm PM991 NVMe PCIe Gen 4 x4 TLC SSD (MZALQ512HALU) for Dell HP Lenovo Laptop Ultrabook Tablet - Internal Solid State Drive (OEM New) - SSK M.2 NVME SATA SSD Enclosure Adapter, USB 3.2 Gen 2 (10 Gbps) to NVME PCI-E SATA M-Key/(B+M) Key Solid State Drive External Enclosure Aluminum Support UASP Trim for SSDs 2242/2260/2280 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/740954697-samsung-512gb-m-2-2242-42mm-pm991-nvme-pcie-gen](https://www.desertcart.tn/products/740954697-samsung-512gb-m-2-2242-42mm-pm991-nvme-pcie-gen) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-23*
