Nvme Vs Nand. NVMe is the fastest, and Mechanical drives are painfully slow. This minimizes the need for garbage collection and reduces write amplification.
First, a quick note about SSDs - they're fast. The deluge of data being created every day shows no sign of abating. But what about NVMe SSDs, how do they differ from standard SATA drives?
Both SATA and NVMe work alongside NAND flash memory, which is the predominant kind of flash memory storage found in most SSDs.
From how to tell them apart just by looking at them and little bit about r.
SATA: It's Time for NAND Flash in the Fast Lane. This minimizes the need for garbage collection and reduces write amplification. QLC NAND's strengths finally make a case for replacing mechanical disks with much faster and more reliable solid-state drives.
