Swapped in the 512GB disk (which actually has only 475GM of usable space on my Windows 10 PC), and everything is working great. Not sure where the other 37GB of space went, but it's a Samsung disk, so am expecting it to last at least a few years.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***Y on 5 June 2025* Wanted to replace my 256GB system disk with something a bit larger.
