This is by far and away the cheapest for a decent pcie ssd. This is not sata speed nvme.
Even compared to SATA ssd prices this is cheaper than some of the deals as of late
256gb is 32.5 cents/gb
512gb is 28.5 cents/gb
Promo code "speedboost"
Recently just bought a crucial mx300 for a little better price/gb but if this was in stock then, I would have done this.
Saying that, for VAST MAJORITY people the real world difference between pcie nvme and sata 3 is hard to detect. But seing how prices of SSD drives are currently. This is a no brain IMO
