Identifying compatible storage upgrades for your system can be a challenge as SSDs are available in multiple form factors. As technology gets slimmer and more lightweight, 2.5-inch SSDs are often too large for cutting-edge systems.

The M.2 form factor is a much smaller SSD that’s about the size of a stick of gum and designed to deliver the near-instant performance of an SSD in space-constrained tablets and ultrabooks. However, it's not compatible with every system.

In addition, there are two interfaces available in the M.2 form factor; SATA and PCIe. These interfaces look very similar, and in some cases, either will work in a computer, but not every computer has the capability to accommodate both interfaces.

Is it compatible with my system?

An extremely valuable tool for determining if an M.2 SSD is compatible with your tablet or ultrabook is the Crucial® Advisor™ tool or System Scanner tool. In just a few clicks, it displays Crucial SSDs that will work in your system – plus, using it guarantees compatibility when you order on

M.2 FAQs

Will a Crucial M.2 SATA SSD work if I have a PCIe connection?
Maybe. Many PC manufacturers configure the M.2 connection to use either a PCIe or a SATA interface. The motherboard automatically configures the correct protocol. 

It's important to note that an M.2 SATA or M.2 PCIe SSD will fit into a PCIe slot, but an M.2 PCIe SSD will not fit into a slot dedicated to M.2 SATA SSDs.

It's best to consult your user manual or the Crucial® Advisor™ tool or System Scanner tool to ensure that you are ordering the correct part.

Will a Crucial M.2 SSD work in my Mac® system?
No. According to Apple® manufacturer specifications, Mac systems are not compatible with Crucial SATA M.2 SSDs.

Are single-sided and double-sided M.2 SSDs interchangeable?
No. Single-sided M.2 sockets on the motherboard support only single-sided M.2 SSDs. However, double-sided M.2 sockets support both double-sided SSDs and single-sided SSDs.

How can I make sure a Crucial M.2 SSD is supported by my system?
The best way to ensure compatibility when you purchase an M.2 SSD on is by using our Crucial® Advisor™ tool or System Scanner tool. Using either tool guarantees compatibility when you order on
