Crucial P2 500GB M.2 NVMe SSD
 

" ... The Crucial P2 SSD is a clear winner if we compare it to other, less expensive M.2 PCIe SSDs. It may not be the fastest, but offers respectable performance, which should satisfy most users. It's also a perfect upgrade for those who purchased a laptop with a slower drive like a SATA or PCIe x2. The P2 is a perfect mix of high performance and high quality at a reasonable price. "
