Hello everyone, today I gonna try to explain the Difference Between SSD NVMe and M.2 SATA and mSATA. So, let’s get started…..
The difference in these drives is in different types of connection to the laptop or PC motherboard.
If you compare the 2.5-inch hard drive and the SSD with the same 2.5-inch form factor,
you will see that the connection interface is the same SATA type.
That is, if you want to replace your old hard drive with a fast SSD drive, there will be
no problems because the SATA interface is compatible with another type of connection – SATA 1, SATA 2 or SATA 3.
But unfortunately, you can’t install an M.2 SSD in the socket of a SATA hard drive – it
is physically impossible.
You also cannot install an M.2 SSD in the socket of the mSATA, these drives, as you can see, also have different connection sockets.
With a hard drive and an SSD with a 2.5-inch form factor, everything is quite simple, and just as without any problems you can replace an mSATA, because this type of drive is available only in one form factor and with one type of connection.
We still have M.2 SSD with different sizes, with different bus types, with different keys,
and from this many people have confusion – “what kind of M.2 SSD should I buy when upgrading my computer.
M.2 SSD has different sizes;
there are only four of them: 2230, 2242, 2260, and the most popular 2280.
The first two numbers indicate the width of the board; the second two numbers are the length.
As a rule, it is indicated how long the M.2 motherboard supports.
Now let’s turn to the types of M.2 drive.
M.2 storage can be in SATA and NVMe types – So what is the difference between M.2 SATA and M.2 NVMe.
SATA M.2 SSD and 2.5-inch SSD – has the same specifications.
M.2 NVMe works on the PCI-E bus, and these are completely different indicators in speed, which is much higher than the SATA bus.
To explain very briefly, NVMe is a type of bus that works much faster than a SATA bus. For example, modern motherboards use SATA III with a maximum speed of 600 MB/s.
NVMe drive provides write speeds up to 3500 MB/s.
This is 7 times more than SATA!
Yes, these two boards are very similar in appearance, but have a slight difference in
the connection socket.
As a rule, an M.2 SATA supports 2 keys “M”+“B”.
The M.2 NVMe drive working on the PCI-E bus will have only one “M” key.
How it all looks in practice.
Take, for example, the Asus Prime Z270P motherboard that has an M.2 socket under the key “M”
onboard, which means that you can install the M2 SATA SSD … as you see, nothing interferes
with the connection … you can also install M2 NVMe SSD – also the connection does not
All the same with laptops.
Let me show you an Asus X570 laptop.
On the motherboard of this laptop, there is a socket for M.2 SSD, also under one key “M”.
and therefore you can connect M.2 SATA and also M.2 NVMe.
But here the question may arise whether the M.2 NVMe will be compatible with your laptop.
For example, an Asus X570 laptop auto-detects which type of M.2 SSD is connected, and in most modern laptops, the BIOS auto-detects the drive.
Many manufacturers install on the motherboard slot for M.2 with the key “M” and with the support of the bus to choose – SATA or PCIe.
That is, you buy M.2 SATA or M2 NVMe and any of the drives will work.
But there are cases when the motherboard works only on one of two buses and does not support,
for example, the new NVMe standard or the old SATA.
To make sure that your motherboard is compatible with the SSD M2 drive.
But it is also worth considering that such a setting may not be in your BIOS, but at
At the same time, your laptop or PC will detect and work with both M.2 SATA and M.2 NVMe.
Therefore, first read the specification of your laptop or motherboard, before buying an M.2 SSD storage.
What to do if you bought M.2 SATA but didn’t check the presence of the M.2 socket on the motherboard, and your laptop only supports 2.5 SATA standard.
In this case, there is a quite large choice of different adapters.
Such an adapter allows you to connect an M.2 SATA and make it a standard 2.5-inch SSD-storage.
But if you try to connect an M.2 NVMe drive to such an adapter, you will not succeed because the connector is not compatible.
There are also adapters for the mSATA storage that make the 2.5 SATA standard out of it.
Even for the 2230 M.2 SATA standard, there is an adapter that converts M.2 SATA to mSATA.
So, this was all about the Difference Between SSD NVMe and M.2 SATA and mSATA.
