The NVMe-connected M.2 SSDs, which have become more prevalent in recent years, are considerably faster than traditional SATA-connected M.2 SSDs. The difference between NVMe and SATA connections is the interface; recent M.2 SSDs are equipped with the faster NVMe interface, which has resulted in a significant improvement in data transfer speed. Whereas the SATA-connected M.2 SSDs had a sequential access speed of about 600MB/s, NVMe-connected M.2 SSDs have evolved to reach speeds of about 8000MB/s for high-speed models. If you add an M.2 SSD to your PC as additional storage, it will increase your data storage capacity and prevent your PC from slowing down if storage is almost full.
When installing an M.2 SSD on your PC, be sure to check whether it is compatible with your motherboard.
Even though they’re all referred to as M.2 SSDs, they come in various sizes. These sizes are often denoted as “Type-XX XX” in product names, where the first two digits represent the height and the last two specify the width. Sometimes, the latter part can have three digits.
The majority of M.2 SSDs used in desktop PC motherboards are of the "Type-2280". For laptop storage replacements, you’d typically look for "Type-2242", but for the purpose of this content, we will only introduce "Type-2280" for motherboards.
Next, let's pay attention to the "Key" which indicates the shape of the notch. The Key refers to the shape of the connection terminal of the M.2 SSD, with major ones being "M-Key", "B-Key", "B&M-Key" etc. You cannot insert the M.2 SSD if the shape of the key does not match the interface on the motherboard side, and it will not operate even if you forcefully insert it.
Currently, motherboards equipped with PCIex4 interface, which allows high-speed data transfer, are mainstream. Since the key that supports PCIex4 is the M-Key only, this content deals with M-Key SSDs. However, if you use an older motherboard with a SATA standard interface, you need to select a B-Key SSD. Please make sure to check the interface of your motherboard before you choose your SSD.
Here are the points to keep in mind when choosing the best M.2 SSDs.
PCIe stands for Peripheral Component Interconnect-Express, which refers to a standard used for data transfer. There are different generations of PCIe, and as of 2024, the mainstream one is PCIe 4.0. Until quite recently, PCIe 3.0 was predominant, but over the next few years, it is predicted that PCIe 5.0 will become popular. It has backward compatibility, so if your motherboard supports PCIe 4.0, you can use not only PCIe 4.0 compliant products but also PCIe 3.0 compatible M.2 SSDs.
In the recently tested products, there were both those that supported up to PCIe 4.0 and those that supported up to PCIe 3.0. Even among the same manufacturer's products, the sequential read numbers varied approximately twofold. The average sequence read for PCIe 4.0 compatible products was 6,855.59MB/s, while that for PCIe 3.0 compatible products was 3,560.88MB/s, a significant difference. Therefore, if your motherboard is compatible, we recommend using PCIe 4.0 compliant products.
The risk of performance issues increases as the temperature of SSDs rise. The threshold for normal operation is 158°F, beyond which a mechanism called thermal throttling is activated, intentionally reducing processing speed to lower the temperature. To use it for a long time without reducing its performance, choose a product that doesn’t easily heat up.
In our tests, none of the products with large heat sinks exceeded 158°F. On the other hand, products without heat sinks sometimes exceeded 158°F. By controlling the temperature increase, both the risk of data crash and performance drop can be prevented, so we recommend products with large heat sinks.
When using an M.2 SSD with a PS5 instead of a PC, it's necessary that it meets the size and speed requirements. The requirements are as indicated in the image, but it's often the case that a product with PCIe 4.0 will meet the speed requirement. Since the temperature tends to rise when using it with a PS5, please be sure to choose a product with a heat sink.
You can filter by "For PS5s" in the ranking section, so if you are using it with a PS5, check for compatible products.

Processing speeds were otherwise average, and it paled in comparison to other PCIe 4.0 SSDs when it came to random access read and write speeds.
A max operating temperature of 179.6℉ could have triggered thermal throttling, resulting in lower performance speeds overall.

The Crucial P3 Plus 1TB PCIe M.2 2280 SSD has above-average sequential read and write speeds and average random access read/write speeds.
Processing speeds were on the higher end among the other SSDs we tested, but with a max operating temperature of 161.6°F, there’s a higher risk of malfunction.

The Western Digital WD Blue SN580 NVMe SSD had more impressive random access read/write speeds relative to its average sequential read/write speeds, but this results in a well-balanced SSD that otherwise performs well.
Against PCMark 10 benchmarks, it scored higher than most of the hard drives in our tests.
The max temperature (159.8℉) barely surpassed the rate at which the risk of failure begins to increase, and there’s no large heat sink attached.

The Samsung 970 EVO Plus NVMe M.2 SSD has a PCIe 3.0x4 interface.
Sequential and random access read/write speeds were middling, especially for the relatively high cost. Processing speeds were also slow, and a 168.8℉ max operating temperature makes it a risky investment if you want an SSD that won’t overheat.

At mybest, we believe the best M.2 SSD can promptly boot games and apps without risk of overheating. To find our top picks, we collected 13 of the best-selling M.2 SSDs from popular brands and retailers across the internet.
Note that for this review, we exclusively evaluated M.2 SSDs with NVMe connections, fit Type-2280 motherboards, and have M-Key connectors. All capacities are fixed at 1TB.
We based our evaluations on the following criteria:
Products we tested
We established our benchmark for user satisfaction in sequential access speed as one that is capable of achieving the advertised speeds of a PCIe 4.0x4 M.2 SSD.
Using the benchmark software Crystal Disk Mark, we measured sequential access read and write speeds. We measured both figures three times, with the averages evaluated at a 5:5 ratio. Scores were based on the highest level of M.2 SSD speeds, which has a maximum theoretical value of 8,000MB/s.
OS: Windows 11 Pro
CPU: Intel Core i7-12700KF
GPU: NVIDIA GeForce RTX 4070 Ti
Memory: 32GB DDR5
We set the benchmark for satisfactory random access speeds as that meets the average advertised speed of a standard gaming SSD.
We used Crystal Disk Mark benchmark software to measure random access read and write values. We performed these tests three times and the average values were evaluated at a 5:5 ratio. Final scores were relative to the upper limit of 700MB/s for fast M.2 SSDs.
OS: Windows 11 Pro
CPU: Intel Core i7-12700KF
GPU: NVIDIA GeForce RTX 4070 Ti
Memory: 32GB DDR5
Our benchmark for acceptable processing speeds was based on the PCMark 10 standard, which covers a comprehensive set of tasks that are typical in today’s standard workplace.
Using PCMark 10, we measured processing speeds through running various apps. The scale of our recommendations was based on a theoretical speed limit of 4,000, the maximum level that PCMark 10 is able to measure.
OS: Windows 11 Pro
CPU: Intel Core i7-12700KF
GPU: NVIDIA GeForce RTX 4070 Ti
Memory: 32GB DDR5
We looked for SSDs with little to no temperature increase, as higher temperatures could lead to slower speeds and drive failure.
We used software to measure the temperature of each SSD and recorded logs from startup until the benchmark test was completed. Considering the risk of failure, we set the maximum limit at 30°C (86°F) and rated products based on how well they stayed below this limit.
