Why is the NVMe SSD interface inherently more efficient than disk-based protocols such as SATA?
The speed at which the electronics industry moves sometimes masks other developments that are incredibly slow-paced and the conversion of storage I/O protocols from hard-disk-centric to solid-state disks (SSDs) is a shining example. Most SSDs currently employ I/O protocols originally … Continue reading
