NVMe Express 1.3 specification, everything you need to know

The NVM Express Organization has confirmed the official release of the NVMe Express 1.3 specification, a new version of the popular protocol known to be used on high-performance PCI-E SSDs.

The latter is important because it means that we do not need to have a standard storage drive (such as a hard disk for example) that acts as a boot drive since our PCI-E SSD can perform that function without problems.

The NVMe Express 1.3 specification is a very important update of this protocol, since it is accompanied by substantial changes that introduce important improvements. Among them we can highlight the following:

  • Automatic check function for checking the integrity of the data.
  • Ability to use multiple boot partitions without relying on the motherboard firmware.
  • Total erase function of stored data, even of those that were in the cache.

As you know those who read us daily PCI-E based SSDs work with x4 slots, a major advantage over traditional SATA connectors as it allows them to achieve much higher read and write speeds.

With a high-performance standard SSD, it is possible to reach 550 MB / s under SATA III, while PCI-E SSDs can easily overcome 2,000 MB/s.

The difference in performance is great but also have very different prices, since in the best case the most economic models double the price of SATA III models with the same capacity.
