NVM Express eliminates those issues by providing a predictable common interface for drives to use, with a common driver specification eliminating the need for device-specific drivers, taking the guesswork out of using these SSDs.

Because of the custom design of these drives, device-specific software drivers were required for use as a result, early PCI Express SSDs were more complicated to use as a boot drive on Windows, or to use with Linux if the vendor did not support it. However, these drives either used AHCI-retaining almost all the random I/O performance bottlenecks-or used a custom interface specification, with operation varying wildly between vendors and, to an extent, between models of the same vendor. This strategy only allowed manufacturers to overcome the 6Gb/s (750MB/s) speed limitation inherent to SATA, with SSDs topping out around 550MB/sec, when accounting for overhead. In the professional and prosumer market, this limitation was overcome by creating SSDs that connected via PCI Express. By late 2010, mainstream consumer SSDs were being bottlenecked by the comparatively limited throughput granted by SATA. These technologies were designed for traditional mechanical hard drives, which have practical physical limitations in random access of data, and the speed with which data can be transferred at once.

Prior to NVM Express, SSDs connected to computers via Serial ATA or SAS, and communicated using Advanced Host Controller Interface (AHCI). NVM Express (NVMe), or the Non-Volatile Memory Host Controller Interface Specification, is a device interface specification that was devised to take advantage of the characteristic advantages of flash-based storage technologies such as NAND and 3D XPoint, marketed as Optane by Intel.
