If you are assembling a new computer or you just want to increase the speed of your laptop, you may have started thinking about SSD. But there are several M.2 SSDs on the market, so if you don’t choose the right ones, you will have to send out more than hundred dollars of water.
One type of SSD available on the market is the SATA SSD. These are just a normal HDD and connect to the computer via the SATA port. They are similar in size to a normal HDD. It’s a great solution for older laptops (those that don’t have an NVMe slot). This was followed by the mSATA SSD, which was smaller in size, thinner and lacking cover, faster than SATA due to its connection via PCIe. They fit small or thin laptops. For modern computers, these are disadvantages.
If you go to a local store and tell them to put an SSD on your computer, they can remove your existing HDD and replace it with a SATA SSD. But with this (PCIe mSATA) you get about 750MB / s. Instead, if you have an NVMe slot you can get an M.2 SSD with the existing HDD.
Thus it is advantageous to have both HDD and SSD. Because SSDs move or hold large files, their time slows down. However, SSD is very advantageous for Windows to boot very fast. So, SSD can use the other HDD you have with Windows, with the software you use most frequently, to retain film or songs.
M.2 SSD Available forms
Originally known as the Next Generation Form Factor (NGFF), M.2 SSD is the modern capacity model that came after mSATA. The SSD technology can be adapted to any computer, but as mentioned earlier, it does not deliver the maximum speed. But when selecting one that fits your motherboard, you will find the following
Depending on the bus type
This option allows the M.2 connector to be connected to the SATA 3.0 port via the AHCI driver. It is very slow and has the advantage of connecting to SSD even on older SATA computers.
This method can be used to add SSD to Duo motherboards and older operating systems. Thus, a connected SSD is faster than an HDD, and a SATA (AHCI) can achieve 600MB / s.
This is based on PCIe. Maximum use of an SSD can be as high as 3GB / s.
You can see that M.2 is just a form factor and that SATA or NVMe are multifaceted due to the type of bus they use to exchange data with the computer.
Depending on the Connector
An M.2 SSD can be broken down into parts depending on how it connects to the motherboard. Since this is located near the motherboard or in the user manual, you should check the SSD before purchasing it. The following types are known as the Key and the SSD is separated by a set of pin between the ends.
There is a single mark after 6 Pin in left side. The data speed is 10Gbit / s.
There is a single mark after 5 Pin in the right side and has a speed of 20Gbit / s data.
Both sets have been designed in this to fit both motherbords. The speed is 10Gbit / s.
Check the support from the BIOS
Even if we choose the right bus type, SSD according to the key, the BIOS version may have other disadvantages. Note that some motherboards do not support booting from PCIe directly. If you plan to use the SSD to boot the operating system quickly, it is wise to check this out before spending.
The key for your computer, such as F2 for Dell computers, is to boot into the BIOS and make sure that its M.2 enable feature allows you to boot. Generally, most PCs with an NVMe slot have little problem with PCIe boot support.
Advantages and disadvantages of M.2 SSD
Computer-based hardware manufacturers are now focusing on producing SSD. Despite it’s disadvantages, SSD is not suitable for long-term use, It has shorter life than HDD. NVMe & M.2 are the only printing presses that will soon become the main storage system for computers. It reduces the computer’s weight, thickness, battery drain speed, and even the time it takes to circulate the data.
The disadvantage of M.2 is that it is not compatible with every computer. even an adapter is paired with it, If you are not be able to boot your PC unless it has a maximum data speed then It’s useless. Also, the m.s SSD costs about four times the price of one gigabyte of HDD.
Both of these disadvantages are time-resolved. When you buy a new computer, the compatibility problem goes away. at this time, SSDs are expensive and HDDs are cheaper.
