In terms of protocol, the SSD M.2 SATA adopts an interface similar to the ordinary SATA interface, which is a relatively low-speed SSD; while the SSD M.2 NVMe is a high-speed SSD that supports the NVMe protocol and uses the PCIe channel. A simple understanding of their characteristics will help computer users who are pursuing high-end configurations to choose solid-state drives correctly.
The hard disk is one of the important components of a computer. For users who pursue high performance, SSD is undoubtedly the best choice. Now SSD has a variety of options for users to choose from. For example, can you tell the difference between SSD M.2 SATA and SSD M.2 NVMe? This article will introduce you to them in an easy-to-understand manner.
M.2 is the designation of the external size of the hard disk. The M.2 interface is a new host interface scheme that is compatible with multiple communication protocols. With the development of technology, PCIe has a transmission rate that meets the needs of users, but it is bulky, so M.2 appears. M.2 is PCIe that can be said to be smaller. The hard disk with M.2 interface has the characteristics of being smaller and thinner and has higher transmission performance.
SATA SSDs are the lowest performing solid-state drives with data transfer rates up to 6Gbps. However, when it comes to understanding the difference between SSD and HDD, SSD is faster. That's because SATA SSDs have three to four times the bandwidth of spinning HDDs, so performance is still better than HDDs. SATA hard drives require two cables to work. One is used to transfer data to the motherboard and the other is used to connect the power supply. Therefore, multiple SATA storage hard drives may affect PC performance. Even writing computers or slim notebooks don't have room for cables. M.2 SATA SSD solves this problem.
NVMe SSDs use the NVMe protocol designed for solid-state drives. Paired with the PCIe bus, NVMe SSDs can deliver the latest levels of performance and speed on the market. By utilizing the PCIe bus, the NVMe M.2 SSD has a theoretical transfer speed of up to 20Gbps, which is much faster than the 6Gbps of the SATA M.2 SSD.
In terms of protocol, the SSD M.2 SATA adopts an interface similar to the ordinary SATA interface, which is a relatively low-speed SSD; while the SSD M.2 NVMe is a high-speed SSD that supports the NVMe protocol and uses the PCIe channel. A simple understanding of their characteristics will help computer users who are pursuing high-end configurations to choose solid-state drives correctly.
