Make your PC fast and responsive with our picks of the best M.2 solid-state drives. The prices of SSDs have been going down in the last few years, making now the best time to upgrade to solid-state storage.

Mechanical hard drives are not only slow but can also be a huge bottleneck when paired with a fast processor. With most of the latest processors capable of handle billions of cycles per second, they have to wait for the hard drive to feed it data. For the best performance for your PC, upgrade to an M.2 solid-state drive.

Manufacturers have lowered the prices of the SSD over the years. They are now more affordable than ever and incredibly fast. More players have joined the race offering stiff competition to Samsung’s EVO SSDs. Many brands are offering high-end solid-state drives from the likes of Western Digital, Gigabyte, Sabrent, and others.

M.2 Socket: Connecting Internal SSDs

M.2 is a form factor for connecting solid-state drives. It’s a small connector, shaped like a stick of gum, included in most of the latest computer motherboards. The M.2 form factor allows laptop manufactures to design thin and lightweight notebooks.

Some boards come with more than one M.2 socket so you can take advantage of RAID for higher read and writes speeds. However, not all motherboards have an M.2 slot. And also, some laptops have M.2 SSD drives soldered in a non-upgradeable format. Therefore, check the availability of an M.2 slot on your motherboard before buying an SSD to upgrade your PC.

M.2 drives come in different sizes. Most are 22mm wide and 80mm long (2280). M.2 socket on a motherboard can support different SSD lengths from 30mm (2230) to 42mm (2242), 60mm (2260), 80mm (2280), or 110mm (22110).


M.2 solid-state drives are either PCIe-based or SATA-based. SATA-based SSDs communicate via the Serial ATA bus interface, and they are most affordable of the two. PCIe-based SSDs, on the other hand, communicate via PCI Express bus taking advantage of the higher bandwidth to offer higher read and write speeds.

M.2 solid-state drives using the SATA interface are limited to 6Gbps, while PCIe 3.0 can reach link speeds of 16Gbps. However, the real-world difference between SATA and PCIe SSDs isn’t colossal. If you are doing daily tasks such as web browsing, office productivity applications, and casual gaming, you’re better off with a SATA SSD.

The value of PCIe-based SSDs is noticeable when transferring large files, working with demanding apps, such as editing 4k videos, and compression/decompression. With the advent of PCIe 4.0, M.2 SSDs are becoming even faster and efficient. However, the cost is also going up with PCIe-based SSDs.

Most of the latest PCIe SSDs support NVMe technology. Non-Volatile Memory Express (NVMe) is a protocol that defines how SSDs communicate via PCI Express. NVMe SSDs bring increased performance and interoperability, perfect for client and enterprise systems. For the best performance and speeds, NVMe SSDs are the best in the market.

All NVMe SSDs are PCIe-based, but not all PCIe-based SSDs support NVMe.

SSD Storage Capacity

Choosing the right storage capacity depends on your needs. 1TB is suitable for most average users, and it often provides the best cost per gigabyte.

For users looking to move their operating system to an SSD and have their data on a hard drive, the 256GB is a good fit, but if you’re a gamer or power user, consider starting from 500GB options. 4TB is a lot of storage for an average user. It is only suitable for professional uses, such as 4K or 8K video editing.
