What is Ultra M.2

What Is Ultra M.2?

Ultra M.2 is a new kind of memory card.
Is it vital to know the history of the product, its benefits, and drawbacks before answering this question?

An Overview of the Past

In reality, ASRock uses the name “Ultra M.2” to differentiate between the earlier M.2 socket (M.2) and a full 32/Gbps M.2 socket (Ultra M.2).
As a result, no comprehensive information about the Ultra M.2 form factor can be found on Wikipedia.

Older M.2 SSDs, as you may be aware, do not support the full bandwidth, despite the fact that bandwidth is an important factor in SSD performance.
The Ultra M.2 slot takes use of those SSDs that are available for genuinely exceptional bandwidth thanks to the advancement in form-factor technology.



Asrock based their Ultra M.2 slot on the previous M.2 slot, which can accommodate up to 4GB/s of bandwidth.
Ultra M.2 slots utilize PCIe 3.0, which has a more modern interface.
The Ultra M2 SSD can provide up to 16GB/s of bandwidth when connected to a PCIe 4.0 motherboard interface.
Modern SSDs, like those from Samsung, have a lot to gain from the new Ultra M.2 slot’s increased bandwidth.
When compared to a standard M.2 socket, the ASRock Ultra M.2 is 46% quicker.
Among other things, Ultra M.2 sockets may be directly linked to the CPU without having to first connect to the chipset.

There are, however, several limitations to the Ultra M2 socket.
For example, the PCIe 3.0 Ultra M.2 slot on the Intel Z97 platform PCIe 3.0 can only be supported by the CPU.
In addition, Ultra M.2 is expected to take four PCIe lanes, which are currently reserved for GPU X16.
As a result, using an Ultra M.2 SSD in a slot that relies on the chipset’s PCIe lanes is pointless. The graphics processor unit and core process of an older computer may be slowed down by the Ultra M.2 slot.

Dual graphics cards may be connected to a CPU’s 16 PCIe 3.0 lanes, for example if it has a 16 PCIe 3.0 model.
The bandwidth between the graphics processor unit and the CPU will be decreased in half if an SSD is inserted into the Ultra M.2 slot.

Ultra M.2 vs M.2

As a rule, Ultra M.2 is more rapid than normal M.2.
Conventional PCIe 3.0 x4 M.2 slots are used in Ultra M.2 ( or SATA )
PCIe 3.0 x2 is the standard for m.2 slots ( or SATA )
M.2 PCIe Gen3 NVMe Socket 3 setup with x4 x4 NVMe
Configuration of M.2 PCIe Gen3 x2 x2 NVMe Socket 2
ASRock uses the phrase “Ultra M.2″ as a marketing ploy.
It simply refers to any M.2 socket that is capable of supporting PCIe Gen3 x4.
SATA may be supported by the same socket, and this is often the case.
According to our research, it is not specified anywhere.
When describing the features of their motherboards, ASRock makes use of the word “overclocking”

Streaming Data

The data transfer rate of the M.2 and Ultra M.2 SSDs seems to be the same, based on user reports.
Is this true?
There is a tiny difference between M.2 and Ultra M.2 SSDs if you are looking for one.
In most circumstances, Ultra M.2 outperforms the M.2 slot in terms of data transfer speed.
When the SSD’s full bandwidth is being used, Ultra M.2 might cause the CPU and graphics processing to slow down.

Differentiating between NVMe, M.2, and SATA 3 M.2

The element that affects the performance of a vehicle’s
Specification for connectors with slots or edges
NVMe as a substitute for mSATA:
In order to communicate with a PCIe storage host controller, the protocol utilizes two or four PCIe lanes
SATA links directly to the CPU subsystem.
Conventional (non-SATA) Connector Protocol

Different Types of M.2 Ports.

It is possible to have two keys on a module card for M2

Only one key may be inserted into an M.2 socket.

For SATA and PCIe x2 ( can use up to 2 lanes )

A typical SATA and PCIe x4 bus symbol is M. ( can use 2 to 4 lanes )

Both kinds of sockets are compatible with the B&M key.

A WiFi key, as the name suggests.

An e key, which is typically used to connect to a WiFi network,
The second option is either SATA or PCIe x2

3: SATA or PCIe ( M keyed )

Aside from solid-state drives, there are additional M.2 card types available ( ex. WiFi )

Do You Need an Ultra M.2 SSD?

It’s possible that you’re thinking whether or not the Ultra M.2 socket is worth your while.
What’s best for you depends on what you’re looking for.
The Ultra M.2 SSD is a good option if you don’t mind paying a premium for improved disc performance.

Make sure to keep in mind the storage interface’s effect on the data transfer speed
SATA, NVMe, or PCIe 4.0 are the three most common storage interfaces for Ultra M.2 SSDs.
NVMe SSDs are often quicker than SATA SSDs.
