I tested the latest M.2 SSDs, and these are my must-have storage drives
There’s no doubt that SSDs (solid-state drives) are faster and more reliable than HDDs (hard disk drives), but not all SSDs are created the same.
One big difference is how they connect to the PC. Regular SSDs and HDDs connect using a port called a SATA (Serial AT Attachment) port, but many modern motherboards offer a faster port built directly to the motherboard using a port called an M.2.
Go to your favorite online retailer, and you’ll be faced with loads of brands all offering an array of different M.2 storage drives. So, which one should you choose? Don’t worry! I’ve simplified things for you and picked out the best M.2 SSDs. The choice now is much easier… but keep in mind the faster and more storage capacity you need, the more it’ll cost you.
I’ll also show you what you need to build yourself an awesome external storage drive using an M.2 drive.

I’ve been putting WD_BLACK storage into gaming PCs for years now, and they never disappoint. This M.2 drive is no exception. It’s super-fast, super reliable, and built from quality components to offer the best lifespan possible.
There are two versions, one with a heatsink and one without, and I recommend the one with the heatsink because it will dissipate heat better, which on turn makes it more reliable and gives you a longer life.

How did we choose these M.2 SSD storage drives?
These are all M.2 drives that I’ve tested and used over the past few months. The tests included stress tests and performance tests (carried out using CrystalDisk and AJA System Test. Along with personal testing, I’ve checked through reviews left by buyers on a number of retailers to confirm reliability. This combination of personal testing and research allowed me to determine the top M.2 SSDs based on their performance, reliability, and user satisfaction. These five drives have stood out as the best options on the market.
What is a M.2 SSD storage drive?
M.2 is a type of solid-state drive (SSD) that is small and used for data storage. It connects directly to the motherboard of a computer, rather than using a traditional SATA III connection. This allows for faster data transfer speeds and improved performance compared to traditional SATA-based SSDs.
How do you pronounce M.2?
In terms of pronunciation, “M.2” is typically pronounced “M-dot-two.”
Do M.2 drives have sizes?
Yes.
You’ll see sizes like 2242, 2260, and 2280.
Here the first two numbers are the width in millimeters — 22mm is the width of commercially available M.2 drives — and the next two (or sometimes three) numbers are the length, again in millimeters.
To know of there are size restrictions to the M.2 drive you can use, check the manual for your computer’s motherboard or enclosure.
I’ve heard that M.2 drives have a “key.” What’s this?
M.2 slots come in two “keyings,” that prevent the drive being inserted the wrong way. Older systems used a B key, and newer systems use an M key.
Modern drives come in two flavors — M key or B+M which will fit into both the newer and older slots.
How do you fit an M.2 drive?
The contacts on the drive slots into its connector at an angle of 30-degree from the motherboard. Not vertically. Not horizontal. At a shallow angle.
Insert the connector all the way into the slot, and then gently push it down flat to the motherboard, and finally fix it to the board using the retaining screw.
Are there alternative M.2 drives worth considering?
Here are a few alternatives to the M.2 drives listed above.
