Among the Dorado series storage systems, which of the following back-end technologies provides the lowest theoretical latency?

Question

Options

• ANVMe
• BSAS
• CPCIe

• A
  74% (20)
• B
  11% (3)
• C
  15% (4)

Explanation

NVMe (Non-Volatile Memory Express) delivers the lowest theoretical latency because it was designed specifically for flash storage and communicates directly over the PCIe bus using a streamlined command queue architecture - dramatically reducing the overhead present in older protocols. SAS (Serial Attached SCSI) is incorrect because it was engineered for traditional spinning hard drives and carries significant protocol overhead, resulting in latencies orders of magnitude higher than NVMe. PCIe is the physical interconnect bus that NVMe runs over, not a storage back-end protocol in itself - confusing the transport layer with the storage protocol is a common trap. A helpful memory tip: think of the initialism NVMe = No Viable Memory latency Equals it - NVMe strips away legacy command layers to talk almost directly to flash cells, making it the speed king among storage back-end technologies.
