Generally speaking, the read/write speed parameter labeled on SSDs refers to sequential read/write, which can actually be seen from the literal meaning of the word, which follows a sequential order during the read/write process, and the higher the value represents the stronger the read/write performance, in units of MB/s.

Sequential read/write is a way to make SSDs perform large-volume file read/write


Onboard Power and Reset buttons are accompanied by a LED Debug Display that puts users in the driving seat. For example, if you're using an SSD to copy a video or other file that's several gigabytes or larger, sequential read/write performance comes into play.

However, we know that sequential read and write speeds may vary depending on the interface, and the current SATA interface or M.2 SATA channel SSDs have a theoretical read/write speed of 6Gb/s, so the read/write speeds of these SSDs are usually between 450MB/s and 600MB/s, while the M.2 NVMe protocol, which goes through PCI-E, can reach up to 1500MB/s or more. reach more than 1500MB/s.
