I’ve done some benchmark comparisons against my Samsung 840 Pro 256GB (AHCI), Samsung 950 Pro 512GB (NVMe) and 1TB Seagate (HDD). All benchmarks were performed using AS SSD Benchmark, CrystalDiskMark and Samsung’s Magician. Real world experience is pretty amazing. Copying a 4GB file from the 840 Pro to the 950 Pro topped out at 2GBps…. yup! That’s 2 GIGABYTES per second! Those kinds of numbers ain’t nothin’ to scoff at. So far I am impressed. Games load significantly faster, although I’ve only tested playing Wolfenstein The New Order and really don’t have any concrete numbers. I would say it takes slightly more than half the time to load levels. Again, nothin’ to scoff at.

I’m including the ancient HDD technology here for the sake of comparison. The highest end HDD cannot dream of even approaching the performance of the lowest end SSD.
