• PCI Express - Wikipedia
• Peripheral Component Interconnect Express
• Style: Serial communication

Every desktop PC  motherboard (opens in new tab)has a number of PCIe slots you can use to add  GPUs(opens in new tab) (aka video cards aka graphics cards),  RAID cards(opens in new tab), Wi-Fi cards or  SSD(opens in new tab) (solid-state drive) add-on cards.

The initialism NVM stands for  non-volatile memory, which is often NAND  flash memory that comes in several physical form factors, including  solid-state drives (SSDs), PCIe add-in cards, and  M.2 cards, the successor to  mSATA cards. NVM Express, as a logical-device interface, has been designed to capitalize on the low  latency and internal parallelism of solid-state storage devices.

• Raid 0
  • doubled speed, no redundancy
  • splits data into blocks and writes them across multiple drives in the array, offering fast read and write speeds
  • does not provide fault tolerance or redundancy, and problems on any of the disks in the array can result in complete data loss

• Thread
• Multi Threading
  Hyper-threading is a process by which a CPU divides up its physical cores into virtual cores that are treated as if they are actually physical cores by the operating system. These virtual cores are also called threads.
  The CPU exposes two execution contexts per physical core. This means that one physical core now works like two “logical cores” that can handle different software threads.
  TLDR: use unused resources (pipeline, register).
