The world of computer hardware can be overwhelming, especially when it comes to the nuances of storage drives. With the increasing popularity of M.2 drives, many users are left wondering whether their M.2 drive is SATA or NVMe. In this article, we will delve into the differences between SATA and NVMe, and provide you with a step-by-step guide on how to identify which type of M.2 drive you have.
Understanding the Basics: SATA vs. NVMe
Before we dive into the identification process, it’s essential to understand the fundamental differences between SATA and NVMe.
SATA (Serial Advanced Technology Attachment) is a traditional interface used for connecting storage devices to a computer’s motherboard. SATA drives use the AHCI (Advanced Host Controller Interface) protocol, which is designed for hard disk drives (HDDs) and solid-state drives (SSDs). SATA drives are widely supported and offer a cost-effective solution for storage needs.
NVMe (Non-Volatile Memory Express), on the other hand, is a newer interface designed specifically for flash storage devices like SSDs. NVMe drives use the NVMe protocol, which is optimized for low latency and high-performance applications. NVMe drives offer faster read and write speeds, making them ideal for demanding tasks like gaming, video editing, and data analytics.
Key Differences Between SATA and NVMe
Here are the key differences between SATA and NVMe:
- Speed: NVMe drives are significantly faster than SATA drives, with read and write speeds reaching up to 5000 MB/s and 4500 MB/s, respectively. SATA drives, on the other hand, have a maximum speed of 600 MB/s.
- Latency: NVMe drives have lower latency compared to SATA drives, which means they can access data more quickly.
- Protocol: SATA drives use the AHCI protocol, while NVMe drives use the NVMe protocol.
- Compatibility: SATA drives are widely supported, while NVMe drives require a compatible motherboard and chipset.
Visual Inspection: Checking the M.2 Drive
One way to identify whether your M.2 drive is SATA or NVMe is to perform a visual inspection. Here’s what you need to look for:
- Keying: M.2 drives have a keying system that determines the type of interface they use. SATA M.2 drives have a B-key, while NVMe M.2 drives have an M-key. However, some M.2 drives may have both B-key and M-key, which can be confusing.
- Labeling: Check the label on the M.2 drive for any indication of the interface type. Some manufacturers may label their drives as “SATA” or “NVMe.”
- Size: M.2 drives come in different sizes, but the most common sizes are 2280 (22mm x 80mm) and 2260 (22mm x 60mm). SATA M.2 drives are more likely to be 2260, while NVMe M.2 drives are more likely to be 2280.
Using Software to Identify the M.2 Drive
If visual inspection doesn’t provide a clear answer, you can use software to identify the M.2 drive. Here are a few options:
- Device Manager: On Windows, you can use the Device Manager to check the M.2 drive’s interface type. To do this, follow these steps:
- Press the Windows key + X and select Device Manager.
- Expand the “Disk drives” section.
- Look for the M.2 drive and check the “Device type” field. If it says “AHCI,” it’s a SATA drive. If it says “NVMe,” it’s an NVMe drive.
- Disk Management: On Windows, you can use the Disk Management tool to check the M.2 drive’s interface type. To do this, follow these steps:
- Press the Windows key + R and type “diskmgmt.msc.”
- Look for the M.2 drive and check the “Disk” field. If it says “AHCI,” it’s a SATA drive. If it says “NVMe,” it’s an NVMe drive.
- Linux: On Linux, you can use the “lspci” command to check the M.2 drive’s interface type. To do this, follow these steps:
- Open a terminal and type “lspci -v.”
- Look for the M.2 drive and check the “Kernel driver” field. If it says “ahci,” it’s a SATA drive. If it says “nvme,” it’s an NVMe drive.
Checking the Motherboard Manual
If you’re still unsure about the M.2 drive’s interface type, you can check the motherboard manual. The manual should provide information on the M.2 slots, including the interface type and any specific requirements.
Common M.2 Slot Configurations
Here are some common M.2 slot configurations:
| M.2 Slot | Interface Type | Keying |
| — | — | — |
| M.2 A | SATA | B-key |
| M.2 B | PCIe x2 | M-key |
| M.2 C | PCIe x4 | M-key |
| M.2 D | SATA + PCIe x2 | B-key + M-key |

What is the difference between SATA and NVMe M.2 SSDs?
SATA and NVMe are two different protocols used by M.2 SSDs to communicate with the computer’s motherboard. SATA (Serial Advanced Technology Attachment) is an older protocol that is commonly used by hard disk drives and older SSDs. It has a maximum bandwidth of 600 MB/s, which can limit the performance of faster SSDs. NVMe (Non-Volatile Memory Express), on the other hand, is a newer protocol designed specifically for SSDs. It has a much higher bandwidth of up to 5000 MB/s, making it ideal for high-performance applications.
In general, NVMe M.2 SSDs are faster and more expensive than SATA M.2 SSDs. However, the actual performance difference between the two may not be noticeable for casual users who only use their computers for basic tasks such as browsing the web, checking email, and word processing. For gamers, video editors, and other power users, however, the faster speeds of NVMe M.2 SSDs can make a significant difference.
How can I identify if my M.2 SSD is SATA or NVMe?
To identify if your M.2 SSD is SATA or NVMe, you can check the specifications of your SSD or the motherboard manual. Most M.2 SSDs have a label or a sticker that indicates the protocol used. You can also check the SSD’s packaging or the manufacturer’s website for more information. Another way to check is to use a system information tool such as CPU-Z or GPU-Z, which can provide detailed information about your computer’s hardware, including the type of M.2 SSD installed.
If you don’t have access to the SSD’s specifications or the motherboard manual, you can also check the M.2 slot on your motherboard. Most motherboards have multiple M.2 slots, and each slot may support a different protocol. The M.2 slot that supports NVMe is usually labeled as “M.2 NVMe” or “M.2 PCIe,” while the SATA M.2 slot is usually labeled as “M.2 SATA.” You can also check the motherboard manual to see which M.2 slot your SSD is installed in.
What are the key characteristics of SATA M.2 SSDs?
SATA M.2 SSDs have several key characteristics that distinguish them from NVMe M.2 SSDs. One of the main characteristics is their speed, which is limited to a maximum bandwidth of 600 MB/s.
