Gigabyte announced the addition of support for 25mm m.2 SSDs to its x670 and x670e motherboards Although it is only 3mm more than the mainstream 22mm, many m.2 disks seem to have limited space, mainly in passive components and power regulation.
At present, nvme SSDs based on m.2 dimensions in the industry have several different lengths, ranging from 30mm to 110mm. Although 30mm disks are rare, 110mm disks are still used in the server field. However, the m.2 has one thing in common, that is, the width is 22mm, otherwise there may be problems in installing disks, especially in laptops.
In any case, motherboard manufacturers now seem to be making room for this slightly wider m.2 overall size and implementing appropriate cooling solutions to match.
