The MX500 is Crucial’s first SSD with flashy new 64-layer 3D NAND memory. This means that the data storage cells inside are stacked on top of one another, 64 deep. In comparison to 2D NAND, which only has a single layer of cells, 3D NAND has much higher storage density. This opens the door to potentially huge storage capacities, as well as making the NAND itself cheaper to produce for a certain capacity.
But why, you may ask, am I reviewing Crucial’s latest SSD tech in an old-school 2.5in SSD? Wouldn’t an NVMe drive’s faster interface give the NAND more of a chance to shine? In short, yes, it would. But not everyone has a motherboard with the requisite NVMe-compatible M.2 slot. After all, motherboards with M.2 slots only started appearing less than three years ago, and as long as my nearly-six-year-old gaming PC can still play The Witcher 3 at 60fps, it ain’t going anywhere. So let’s see what the new Crucial MX500 is capable of, and whether it can upset our previously established list of Best SSDs.
