Keys and Sockets (Anahtarlar ve Soketler):

M.2 SSDs typically use three common keys:
- B
- M
- B+M

Uyumluluk İzahı 1:

Bilgisayarın üzerinde yer alan “M.2 B key slot”a sadece B+M key SSD harddiskler uyumludur.
Bilgisayarın üzerinde yer alan “M.2 M key slot”a
- hem M key SSD harddiskler,
- hem de B+M key SSD harddiskler uyumludur.

What is AHCI SSD?
- Advanced Host Controller Interface, or AHCI, is a technical standard for an interface that enables software to communicate with Serial ATA (SATA) devices. These peripheral component interconnect (PCI)-class devices move data between system memory and SATA storage media.
AHCI vs. NVMe
- Nonvolatile memory express (NVMe) is a communication interface developed for NAND flash and high-performance SSDs using PCI Express card slot technology. The NVMe controller directly interfaces with the host central processing unit, whereas AHCI interfaces with the SATA device controller. Because it was specifically developed for SSDs, NVMe is faster than AHCI, reduces latency and provides better — over 1 million — I/O operations per second. NVMe significantly increases the number of I/O queues possible with queue depths of as much as 65,000.
- Communication drivers are used by operating systems to communicate data with storage devices. NVMe drivers are faster than AHCI drivers, which are commonly found in SATA interfaces.
  - NVMe is designed specifically for SSDs with flash technology, making it faster than AHCI drivers that were designed for common hard drives with spinning disk technology.
  - While NVMe has 64K command queues and can send 64K commands per queue, AHCI has only one command queue and can send only thirty-two commands per queue.
  - With AHCI drivers, commands utilise high CPU cycles with a latency of 6 microseconds while NVMe driver commands utilise low CPU cycles with a latency of 2.8 microseconds.
  - The NVMe driver communicates directly with the system CPU but the AHCI must communicate with the SATA controller. The AHCI has IOPS (Input/Output Operations Per Second) of up to 100K while the NVMe has IOPS of over 1 million. IOPS (Input/Output Operations Per Second, pronounced i-ops) is a common performance measurement used to benchmark computer storage devices.
Hangisi daha hızlı: Is m key better than b key?
- The PCIe bus is faster than a SATA bus, and an M-key SSD is faster than a B-key SSD. Note: All these performance indicators are relative to the Bus and Bus interface. There are other factors that determine individual SSD performance that are not addressed here. *
- An M.2 SSD that has only the M key, as pictured, will be an NVMe SSD. NVMe M.2 SSDs utilise the NVMe protocol that was specifically designed for SSDs. When paired with the PCIe bus, an NVMe SSD offers the latest levels of performance and speed. * (Anahtar sağ uçtaysa, yani “M anahtar” ise, o M.2 daha hızlıdır.)
