With the continuous advancement of technology, we have ushered in the era of PCIE7.0 standard. This new standard has made a qualitative leap in transmission speed, and its x16 bidirectional transmission capacity is as high as 512GB/s. However, for the vast consumer market, the performance of PCIE4.0 is more than enough. PCIE7.0 is more used in high-end fields such as quantum computing, hyperscale data centers and cloud applications.

Looking back at the development history of PCIE, from PCIE1.0 in 2003 to PCIE4.0 in 2016, each update has brought about a doubling of bandwidth. Taking PCIE3.0 and PCIE4.0 as an example, we can more intuitively see the significant difference in speed between the two. The theoretical speed limit of PCIE3.0x4 is 3938.4MB/s, while PCIE4.0x4 soars to 7.88GB/s, which is equivalent to 7500MB/s. This is undoubtedly a big leap in the performance of solid-state drives. Although PCIE4.0 has different models such as entry-level, mid-range and high-end, the performance of even the entry-level PCIE4.0 solid-state drive is comparable to the flagship version of PCIE3.0.

PCIE4.0 solid-state drives have many advantages over PCIE3.0, such as M.2 interface compatibility, twice the sequential read and write speed, faster 4K random read and write, and longer service life. Although in daily use, users may not be able to clearly perceive the significant improvement of PCIE4.0 compared to PCIE3.0, but compared with the traditional SATA interface solid-state drive, its speed improvement can be described as a world of difference, especially in the gaming experience aspect.

In terms of game loading speed, both PCIE3.0 and PCIE4.0 SSDs are significantly faster than SATA SSDs. However, users can hardly perceive the obvious difference between PCIE3.0 and PCIE4.0. Therefore, for gamers, whether they choose PCIE3.0 or PCIE4.0 SSDs, they can get a satisfactory experience.
