The M.2 form factor has become the de facto standard for high-speed storage, but not all M.2 slots are created equal. This guide will delve into the various types of MM.2 vs PCIe vs SATA vs NVMe: What's the Difference? - Corsair.2 slots and their corresponding keys, helping you navigate the world of SATA and NVMe SSDs.

The Evolution of Storage Interfaces: SATA vs. NVMe

Historically, the SATA interface has been the workhorse for storage devices. SATA uses an older interface with one designed around hard drives, offering good performance for common applicationsM.2 vs PCIe vs SATA vs NVMe: What's the Difference? - Corsair. However, with the advent of solid-state drives (SSDs), the limitations of SATA became apparent.What slot does the NVMe SSD go into? This led to the development of NVMe (Non-Volatile Memory Express), a protocol specifically designed for flash memory. NVMe SSDs communicate directly with the system CPU via PCIe (Peripheral Component Interconnect Express) slots, offering significantly faster data transfer speeds compared to SATA. In fact, PCIe is the standard interface for NVMe, and NVMe SSDs are three to ten times faster than their SATA counterpartsUnderstanding SSD Technology: NVMe, SATA, M.2.

The M.2 form factor has largely replaced older interfaces like mSATA, offering a more versatile and compact solution. An M.2 slot can support either SATA or NVMe protocols, and understanding the physical keys on an M.2 SSD is essential for determining compatibility.

There are three primary M2 Types of M.2 SSDs: SATA and NVMe - Kingston Technology.2 SSD types: SATA and NVMe.

M.2 SSD Protocols: SATA and NVMe

* M.Understanding SSD Technology: NVMe, SATA, M.22 SATA SSDs: These drives utilize the SATA interface, meaning they are limited by SATA’s maximum theoretical bandwidth of 600 MB/s. While still faster than traditional hard drives, they do not unlock the full potential of M.2 storage. SSDs using the SATA bus tend to use B-keys.

* M.2 NVMe SSDs: These drives leverage the PCIe interface, offering substantially higher speeds.PCIe 3.0 vs 4.0: Speed, Compatibility, and the Right SSD for You - Adata The PCIe slot provides multiple lanes for data transfer, with common configurations including PCIe 2M.2 Key and Socket Types: Understanding B, M & B ....0 x4, PCIe 3Two types of M.2 SSDs: SATA and NVMe.0 x4, PCIe 4.0 x4, and PCIe 5.Types of M.2 Drives & Slots (An In-Depth Guide)0 x4How to add an M.2 SSD to a PS5 console.

This prevents users from accidentally installing a SATA drive into an NVMe slot or vice-versa, or a drive with an incompatible pin configuration.

The most common M.2 key types you'll encounter are:

* B Key: These slots typically support SATA and PCIe x2 speeds.2017年8月3日—The M.2 format is designed for manufacturers toreplace a variety of specific devices, do it in a tiny space, and require very little power. SSDs with a B key often utilize the SATA bus, or PCIe x2 lanes for NVMe communication.Swipe through to explore the differenttypesand sizes of: 1️⃣ RAM: From legacy DDR to the lightning-fast DDR5. 2️⃣ SSDs: SATA, External, and the ... A B key has 6 pins to the right of the notch.

* M Key: These slots are designed for PCIe x4 speeds, maximizing the bandwidth available for NVMe SSDsMotherboard via one of:PCIe 2.0 ×4; PCIe 3.0 ×4; PCIe 4.0 ×4; PCIe 5.0 ×4; Serial ATA 3.0 · USB 3.0.. An M key has 5 pins to the right of the notch.

* B+M Key: This is a combination key that allows compatibility with both B key and M key slots.Types of SSD Form Factors An M.2 drive with a B+M key typically uses SATA or PCIe x2 lanes. Some NVMe drives are keyed for both B & M slots, allowing the drive to be inserted into either type of connector, operating at the speed offered by the slot (usually PCIe x2)NVM Express.

Other less common M.2 key types include A Key (primarily for Wi-Fi and Bluetooth modules) and E Key (also for wireless modules). You might also see A+E Key. The keying system ensures that M.2 cards are specifically designed for their intended function and interface.

The first two digits refer to the width (22mm), and the last two or three digits refer to the length in millimeters. The most common SSD lengths are 2280 (80mm) and 2230 (30mm). Ensure your M.2 slot can accommodate the physical size of your chosen NVMe SSD.

For example, a motherboard might have a single M.2 NVMe slot supporting PCIe 4.0 x4. This slot would typically use an M keyTypes of SSD Form Factors. If you have a dual M.2 slot motherboard, it's important to check the documentation for each slot to understand its protocol and keying capabilities.2024年3月29日—M.2 cards come in various key types, includingA, E, B, M, A+E, and B+M key.
