A technician is upgrading a desktop's storage with the fastest option available. The desktop's motherboard is equipped with SATA III, NVMe, and IDE. Which of the following should the technician choose

The correct answer is A. PCIe SSD connected via NVMe interface. NVMe (Non-Volatile Memory Express) is a protocol designed specifically for SSDs that communicates directly over the PCIe bus, bypassing the slower AHCI protocol used by SATA. A PCIe SSD using the NVMe interface delivers sequential read speeds of 3,000–7,000+ MB/s, far exceeding S

Question

A technician is upgrading a desktop's storage with the fastest option available. The desktop's motherboard is equipped with SATA III, NVMe, and IDE. Which of the following should the technician choose for the best performance?

Options

  • APCIe SSD connected via NVMe interface
  • B3.5in (8.9cm) 10.000rpm HDD connected via IDE interface
  • CM.2 SSD connected via SATA interface
  • D2.5in (6.35cm) SSD connected via SATA interface

Explanation

NVMe (Non-Volatile Memory Express) is a protocol designed specifically for SSDs that communicates directly over the PCIe bus, bypassing the slower AHCI protocol used by SATA. A PCIe SSD using the NVMe interface delivers sequential read speeds of 3,000–7,000+ MB/s, far exceeding SATA III's 600 MB/s ceiling. An M.2 SSD via SATA (C) and a 2.5in SSD via SATA (D) are both limited to ~600 MB/s. An IDE HDD at 10,000 RPM (B) is the slowest option, as IDE tops out at ~133 MB/s and spinning disks are inherently slower than SSDs.
