SATA vs mSATA vs NGFF M.2 - WHICH one is the best one for my setup

Solid-state drives (SSDs) are a type of storage device that uses flash memory to store data. Unlike hard disk drives (HDDs), SSDs have no moving parts and can access data much faster.

SSDs also consume less power, generate less heat, and are more reliable than HDDs. However, SSDs are also more expensive and have lower storage capacity than HDDs.

Different types of SSD interfaces connect the SSD to the motherboard of a computer. The most common ones are Serial ATA (SATA), mini-SATA (mSATA), and Next Generation Form Factor (M.2).

These interfaces differ in their size, shape, speed, and compatibility. Choosing the right SSD interface depends on the device and the user’s needs.

The main purpose of this article is to compare and contrast the features, benefits, and drawbacks of SATA, mSATA, and M.2 SSDs. The article will also provide examples of devices that use these SSD interfaces and give recommendations for choosing the best storage option.

The Basics

Before we get into the specifics, let’s clarify what we’re talking about:

  • SATA (Serial ATA): This is the most common interface for connecting SSDs and HDDs to the motherboard. It’s been around for a while and is known for its reliability.
  • mSATA (mini-SATA): As the name suggests, this is a smaller version of SATA, designed for laptops and smaller devices.
  • NGFF M.2: This is the newest standard, offering a range of sizes and configurations. It’s known for its high speed and versatility.

SATA: The Reliable Workhorse

SATA SSDs are like the dependable family car. They get the job done without much fuss.

Here’s why you might choose a SATA SSD.


Almost every desktop and laptop made in the last decade supports SATA. This means you don’t have to worry about compatibility issues or adapters when upgrading your storage device.

SATA SSDs can also work with older systems that have SATA II or SATA I ports, although they will operate at lower speeds.

Easy to Install

If you can plug in a cable, you can install a SATA SSD. All you need is a SATA data cable and a SATA power cable, which are usually included with your SSD or your motherboard.

You can also use a 2.5-inch to 3.5-inch adapter or a mounting bracket if you want to install your SSD on a desktop PC. SATA SSDs are also easy to clone or migrate from your old HDD using software tools.

But, There’s a Catch

SATA SSDs are not the fastest kids on the block. Their speed is limited by the SATA interface, which maxes out at 600 MB/s.

For everyday tasks, this is more than enough, but it might not cut it for high-end gaming or heavy video editing.

mSATA: Small but Mighty

mSATA SSDs are like sports cars: small, fast, and a bit more expensive.

Compact Devices

If you have a small laptop or a mini-PC, mSATA is perfect. mSATA SSDs have a smaller form factor than SATA SSDs, which means they can fit in devices with limited space.


In addition to utilizing the same data transfer protocol as SATA, mSATA SSDs possess a smaller size, which can contribute to increased speed. With the ability to reach speeds of up to 6Gb/s, equivalent to SATA III, mSATA SSDs offer improved performance due to reduced circuitry and components.

In terms of random read and write speeds, the mSATA SSD achieves 97,000 IOPS and 88,000 IOPS respectively, slightly lower than the SATA SSD’s 98,000 IOPS for random reading and 90,000 IOPS for random writing.

The Downsides

mSATA SSDs are smaller but less compatible and more costly than SATA SSDs. They have lower speed and capacity limits and may not work with some devices.

NGFF M.2: The Speed Demon


If you are looking for the fastest and most powerful SSDs on the market, you should consider NGFF M.2 SSDs. These are the supercars of the SSD world, as they offer unparalleled speed and performance for your data storage needs.

Blazing Fast

One of the main advantages of M.2 SSDs is their incredible speed. Unlike SATA SSDs, which use the AHCI protocol that was designed for hard disk drives, M.2 SSDs can use the NVMe protocol that was specifically developed for flash-based storage.

This allows M.2 SSDs to achieve speeds of up to 3500 MB/s, which is nearly six times faster than the maximum speed of SATA SSDs (600 MB/s). With such high speeds, you can boot your system, load your applications, and transfer your files in a matter of seconds.


Another benefit of M.2 SSDs is their versatility. M.2 slots can accommodate different lengths of SSDs, ranging from 30 mm to 110 mm.

This means that M.2 SSDs can fit in various devices, such as laptops, desktops, and servers. Moreover, M.2 SSDs can use different interfaces, such as SATA, PCIe, or USB, depending on the device’s specifications.

This gives you more options to choose the best SSD for your device and your budget.


M.2 SSDs are also future-proof, as they are the newest and most advanced standard for SSDs. M.2 is where the industry is heading, as more and more manufacturers are adopting it for their products.

For example, Intel has launched its Optane SSDs, which use the M.2 form factor and the NVMe protocol to deliver unprecedented performance and endurance. M.2 SSDs are also compatible with the latest technologies, such as 3D NAND flash, which increases the storage capacity and reliability of SSDs.

By choosing M.2 SSDs, you can ensure that your device will be ready for the future of data storage.

The Trade-Offs

M.2 SSDs, while offering advanced features and high speeds, come with certain drawbacks.

  • Higher Cost: M.2 SSDs are typically more expensive than SATA SSDs.
  • Limited Capacity: The maximum storage capacity for M.2 SSDs is currently lower than SATA SSDs. The largest M.2 SSDs offer up to 8TB, whereas SATA SSDs are available up to 16 TB.
  • Compatibility Issues: Not all computers have M.2 slots, and even if they do, these slots might be used for other components. Additionally, your device’s BIOS must support booting from an M.2 SSD. M.2 SSDs are generally compatible with PCIe 3.0 or 4.0 interfaces but may work at reduced speeds depending on the specific interface.
  • Heat Generation: M.2 SSDs can generate significant heat, especially under heavy use, potentially impacting performance and lifespan. Managing this heat may require additional cooling solutions like heatsinks or fans, which can add to the cost and complexity of your setup. It’s important to monitor the temperature and avoid exposing the SSD to extreme heat.
