While building or upgrading a PC, using powerful components helps in achieving good performance. One such component is the SSDs which have become a popular alternative to the HDDs. To form a connection between the SSD and the motherboard, several adapters are used. Amongst these adapters, the M.2 PCIe adapters are the most eligible hardware component.
The M.2 PCIe adapters are popular as they offer connectivity with the older generations of motherboards. They use the PCIe interface, which is known for its faster data transfer speed. These adapters are thereby used by users who wish to upgrade to a faster storage drive. Before selecting an M.2 adapter for your PC, it is important to be aware of some governing factors.
- Compatibility: Compatibility is the most important factor for the M.2 PCIe adapter. To successfully install the SSD with this adapter, both components must fit perfectly with each other. The M or B Key SSDs are selected depending on their installation. Besides this, interface compatibility is crucial to ensure uninterrupted connectivity. Compatibility of the form factor like M.2 helps in avoiding mismatched installation.
- Speed: A good data transmission speed is desirable when huge chunks of data are involved. The speed is thereby considered while buying an M.2 PCIe adapter. Connectivity with a PCIe interface of the motherboard is achieved with lower latency. Most of the M.2 PCIe adapters comfortably deliver read and write speeds of 2 to 3.5 GBps.
- PCIe Version: There are several versions of the PCIe interface which affect the data transmission speed. Each generation has its own speed limit and compatibility factors. The earlier versions of PCIe are slower and do not support backward compatibility. The new versions are backward compatible and offer a decent data transfer speed. PCIe 3.0 and 4.0 are popularly used versions.
By understanding these factors, the user can sort out suitable M.2 PCIe adapters from a list. Given the popularity of upgrading PCs with hardware components, the markets are flooded with several options. This article helps in the selection process by offering a compiled list of the best M.2 PCIe adapters. A “Buying Guide“ is also explained to further ease the sorting process.

Buying Guide For The Best M.2 PCIe Adapter
The M.2 PCIe adapters have become a good alternative to the slower SATA adapters. With up to 3 times faster performance, these adapters are suitable for users who seek upgradation of their PC systems. We have already gone through the list of the best M.2 PCIe adapters. To understand some of the governing parameters, we advise you to go through this buying guide. It provides crucial information related to these adapters to ease the selection process.
1. Compatibility
Compatibility is the most important factor for these adapters since it affects other factors. The compatibility of the adapter is checked for several sub-factors. The pin layout should match the connector perfectly. The M.2 PCIe adapters are available in three different types of pin or key layouts: B, M, and M+B. The compatible form factors allow better installation of the adapter and SSD. The width and length of the SSDs affect the connectivity with the PCIe adapter. Most of the M.2 PCIe adapters have a common 22 mm width and a varying length between 30 to 100 mm.
2. Speed
The whole point of upgrading the PCIe adapters is to achieve higher data transmission speed. The speed includes both the reading as well as the writing speed offered by the adapter. The current generation of PCIe adapters offers higher speeds by eliminating latency in the connections. The speed is also dependent on the multiple lanes of the PCIe interface. The number of lanes varies between x4 to x16 where more lanes result in enhanced speeds. The M.2 PCIe adapters offer a reading and writing speed of 32 Gigabits per second, approximately 4 Gigabytes per second.
3. PCIe Version
The version of the PCIe interface affects the data transfer rate and hence is given importance. The earliest PCIe 1.0 offered a data transfer speed of 250 MBps. The speed was almost double in the PCIe 2.0 version where 500 to 600 MBps was easily achieved. The PCIe 3.0 included some major changes like backward compatibility and a data transfer rate of 1 GBps. The lanes were also increased to ensure faster speeds. The PCIe 4.0 was introduced with a faster data transfer rate of 2 GB per lane. Its x16 lanes can reach a speed of 32 Gbps or 4 GBps. This is the most current version with backward compatibility with previous versions.
4. No. of Drives
The PCIe adapter is used to connect storage drives to the motherboard. The capacity of drives differs from model to model. Considering the form factor of the drives and available slots, the capacity of the adapter can be decided. The M.2 drives easily fit the M.2 PCIe adapters leaving space for other drives. The M.2 PCIe adapters offer over two M.2 slots as a standard. The premium versions of the adapters offer more than 2 slots up to a total of 4 slots. The users can also choose adapter add-in cards to accommodate more drives.
5. Cooling
The PCIe adapters with NVME SSDs offer excellent data transmission speed. With the faster speed, a lot of heat is generated in and around the adapter. To ensure proper cooling of the adapters, it is fitted with cooling features. Heat sinks are the most popularly used features for heat removal. These are fitted on the updater edges to allow heat transfer via air circulation. Other cooling methods include the external coolers which circulate air over the components of the motherboard. Some users even use thermal pads and pastes to assist in cooling.
6. Warranty
Warranty is an important safety cover for PCIe adapters. These components are electrical units and thereby vulnerable to various damages. The user cannot keep buying new adapters every time they are damaged. The warranty period offers free repairs and replacement to the damaged PCIe adapters. Most of the brands offer a warranty of 1 year over their products. This warranty period can be further increased via warranty extension programs.
Best M.2 PCIe Adapter FAQs –
Ans: Both M.2 PCIe and M.2 SATA adapters offer connectivity to the SSDs with the motherboard. One major difference between these two adapters is the data transmission speed. The SATA III adapters have a limited speed of over 600 MBps while the PCIe goes up to 2 GBps per lane. Another difference is the number of lanes offered by PCIe (x4 to x16) is more than the single lane of SATA adapters.
Ans: The M.2 PCIe 4.0 SSD can be inserted into the M.2 PCIe 5.0 slot. In this case, the data transmission speed will be of the 4.0 version. This connectivity is possible due to the backward compatibility feature of the PCIe adapters. It enables support for the older generation PCIe components to connect the latest generation of PCIe slots. The PCIe 5.0 adapters can also be used with a PCIe 3.0 SSD.
Ans: Like any other component of a PC, the M.2 adapters also generate heat during operation. The temperature does not go to extreme levels but having a cooling solution is always beneficial. It avoids the drop in performance of the adapter due to overheating. The heat sinks are popularly used for the M.2 adapters since they are cheaper and allow heat removal. The heatsink’s shape also helps in efficiently transferring heat from the adapter’s surface.
Ans: The maximum speed of an M.2 PCIe adapter is dependent on factors like version and number of lanes. The new versions of PCIe adapters like the 4.0 will deliver data at higher speeds than the 3.0 version. With the help of multiple lanes, the speed can go up to 2 GBps for each lane. The combined speed of the M.2 PCIe adapter can go up to 4GBps.
