Crucial finally announces their first SSDs M.2 NVMe
It was already unusual for a manufacturer with the category and history of Crucial (which is actually a Micron Technology brand) not to have last generation solid state devices in its catalog, but fortunately that is over as it just announced its new generation of high-performance SSDs with M.2 format and which use the NVMe protocol, using a PCI-Express interface.
You know that since long time ago the SSDs with SATA 3 interface reached their performance limit, which is why manufacturers of storage devices had to look for other alternatives to further improve and they found in the PCI-Express lanes the ideal solution, thanks to their high bandwidth (they use a PCI-Express rail of 32 Gb/s). Of course it was difficult to use this interface with the usual format of 2.5 inches, so the M.2/U.2 format is now the chosen one thanks to the small space it occupies and to its versatility (with M.2 SSDs variants and an adapter which connects directly to a PCI-Express x4 of the motherboard).
