Perhaps you’ve heard of SSDs or HDDs? Both types of hard drives have unique features for computers. In particular, SSD hard drive products, especially NVMe SSDs, are often more expensive. So what is NVMe SSD? Why is this type of hard drive more expensive? Should they be used or not? Let’s find out in the article below!
What is NVMe SSD Storage?
As you know, SSD (Solid State Drive) is a type of solid-state drive dedicated to laptops or desktop computers. So what is NVMe SSD? NVMe stands for Non-Volatile Memory express, which translates to “immutable memory”.
NVMe exists in many physical forms, in which SSD hard drives are the most. NVMe is called the latest computer storage interface and can read and write quite quickly.
In engineering, NVMe is a high-performance controller motherboard interface used in SSD hard drives, PCIe interface. So what is a PCIe SSD? This is a type of solid-state drive that uses a PCIe interface that connects directly to the motherboard. Thus, unlike SATA SSD hard drives, this hard driveline will significantly faster be processing capabilities with a direct connection.
The M2 PCIe NVMe SSD has pretty fast read and write speeds. Usually, it will support 2 speed standards, PCIe 3.0 and PCIe 4.0. These devices are often used in high-end computer systems and laptops. The maximum bandwidth of the 3.0 version is 4GB/s, while the 4.0 version is 8GB/s. Thus, the processing performance of the computer will be very high. Currently, Intel supports the PCIe 3.0 version, and AMD has supported the latest 4.0 version.
With the above information, you can understand an M2 NVMe SSD, or what is an M2 PCIe SSD? They are all popular hard drives, supporting the CPU to process information.
Advantages of NVMe SSDs
Understanding what NVMe SSD is is not difficult, but not everyone knows its advantages to computers. Here are some advantages that this hard drive brings:
- For low computer latency, the speed is greater than ATA or SATA. Because it is plugged directly into the motherboard without going through an intermediary, the recording ability of this hard drive is also faster. If NAND is upgraded in the future, NVMe will be even faster.
- Multiple ports, for great scalability, support 64K queues and commands. A group of ports connect directly to the CPU for maximum performance and efficiency. Current PCIe SSDs offer x4 lanes and additional ports, so computer performance is also higher.
- It consumes less power, especially when in standby mode. With low power standby mode, reduce consumption to less than 2mW, thereby increasing energy saving. In addition, current power states also help computers reduce power consumption, suitable for many businesses.
- Security support for computers and data. NVMe supports Security container commands, allowing SSDs to offer powerful data security solutions.
With just a simple hard drive, but the things that NVMe SSDs bring are extremely powerful. That is why they are not cheap in the market.
Shapes and sizes of SSD M2 NVMe
As for the M2 PCIe NVMe SSD standard, the overall design looks like a regular computer RAM stick. The width of the hard drive is 22mm. The right side has a pin slot (different from SATA SSDs with 2 pin slots).
Currently, M2 PCIe SSDs have up to 3 standards, 2242, 2260 and 2280. Corresponding to them are the hard drive lengths of 42mm, 60mm and 80mm. In which, the most popular type is 22x80mm. Hard drive speed can reach 32Gbps, 3500MB/s. Manufacturers release the capacity from 250GB, 520GB, 1TB, 2TB…
The size of the NVMe SSD line is usually much more compact, not taking up the area of the computer. Therefore, they are suitable for all popular computers today. Moreover, the acceleration and peak speed are also far behind SATA.
Should you buy an NVMe SSD or not?
Many people who want to upgrade their computer ask what is an NVME SSD and should it be used? Depending on the amount of work, your usage needs to install more SSD hard drives. For example, professions, graphics, programming, video editors, 4K gaming … should use more NVMe SSDs. Because SSDs are inherently much faster than HDDs, NVMe technology also doubles processing speed.
Currently, the price of NVMe SSD products is also much more affordable. Depending on the capacity, the manufacturer price a hard drive. Therefore, the NVMe SSD product lines also reach more customers.
Moreover, before replacing the hard drive, you must choose the right hard drive. Some machines support the new PCIe port, but some machines don’t. Therefore, you must see if your computer is guaranteed to support the hard drive.
In addition, regular SATA hard drives also have quite stable speeds. They only slow down after being used for quite a while, so if you don’t need to use the computer for large, cumbersome tasks, it is not recommended to install more PCIe. This also helps you reduce a significant part of the cost to upgrade your computer system accordingly.
Hopefully, the information about what NVMe SSD is above has helped you have a comprehensive view of this new generation of the hard drive. In general, adding a hard drive will help increase computer productivity and reduce processing time. However, it also depends on the budget and the amount of work to calculate an M2 PCIe NVMe SSD hard drive installation.
