Newegg via eBay offers the HP 250GB M.2 NVMe 3D TLC NAND 3.0 Solid State Drive for $39.99 with free shipping. That's the lowest price we could find by $10 and tied with our mention from two weeks ago as the cheapest 250GB M.2 SSD we've seen. It features max sequential read speeds of up to 2,100MB/s and write speeds of up to 1,500MB/s.
