Plextor M6e SSD & M.2 Drive Standard Overview

The video provides a technical overview of the Plextor M6e solid state drive and the M.2 form factor, focusing on how PCI Express is used in this configuration. It explains that the M6e arrives on a PCIe 4x add‑in card, creating a direct path from the PCIe bus to the drive and avoiding the traditional SATA bottlenecks. The presenter emphasizes that this approach uses native PCI Express all the way through to the drive’s controller, rather than a RAID intermediary as seen in some older solutions. He notes that the M.2 interface on the card is designed to maximize feature density in a small footprint, enabling desktop-level performance in thin and light devices. The discussion also breaks down the physical layout, detailing that the connector is keyed to indicate required PCIe and SATA/AHCI interfaces, and that a typical M.2 card taps into PCI Express, SATA, or SATA Express depending on the design. In addition to the form factor explanation, the video covers some high level specifications of the M6e, such as its two PCIe Gen 2 lanes, a theoretical throughput around 1,000 MB/s, and a large emphasis on compatibility and driverless operation through AHCI rather than NVMe. The presenter finally frames the M6e as a first native PCI Express consumer SSD and expresses enthusiasm about the direction of PCIe based storage, despite acknowledging some real world complexity and the cost associated with this early implementation.
