Recently the price of SSDs has been reduced, and even the editors have read the heartbeat, especially since many comments have been related to SSDs. And now more and more friends are also concerned about NVME solid state hard drives. Simply let me talk about the NVME solid state thing today.

Where is the NVME hard drive?

Simply put, NVME solid state is the interface protocol directly with the CPU through the PCI-E channel. Without the concept of transfer, the speed of direct connection is of course much faster, so you can see the terrible transmission rate of gigabytes per second, and 4K random read and write performance has a qualitative improvement compared to SATA solid state drives.

In terms of use, the time for the game to read the (progress) bar can be greatly shortened. The SSD using NVME is basically flashed and there is almost no waiting; the solid state using ordinary SATA takes a few seconds, wait a minute; the ordinary mechanical hard drive needs The longer it takes, it is not an exaggeration to do a preparatory activity.

It should be noted that whether it is SATA or NVME protocol SSDs, the difference in response time and CPU usage is almost negligible, and there is no essential difference in this regard.

Another thing not to confuse is that NVME and SATA are both channel protocols, that is, the difference in data communication methods is different from what style of interface is used. Of course, NVME is currently in the form of M.2, and the SATA channels are much messier. Common ones include ordinary SATA 6G interfaces, as well as M.2 (sata) and older Msata.

Want to use NVME? Trouble is a must!

Hard disks that use the NVME interface protocol are not as simple as plugging in without a brain. After all, they are relatively new things and have certain installation requirements for the system. The first is to support the system, native support after Windows8.1, Windows7 system needs to integrate the driver before making the installation disk (many Windows 7 image files are "modified" by netizens), Only such a system can be installed on a NVME SSD. As for Windows XP, don't think about it ... yes, no matter what version of the system, you must use UEFI boot mode, this is necessary, otherwise you can not install and start!

In addition to the system, the motherboard should also be supported. It is known that Intel 90/100/200/300 series chipset motherboards and AMD A320 / B350 / X370 / X470 / X399 series chipset motherboards support NVME, which means that it is not Any motherboard that is too old can be supported. After all, the NVME specification was formulated as early as 2011.

Why is NVME SSD too expensive?

The last question is about SSDs with the same capacity. Why does NVME cost nearly twice as much. Unless the special price is the case. What exactly is this for? The answer is relatively simple: the main reason is that the new master is expensive! To put it plainly is to make money, of course, the return paid is quite impressive, close to double the price, at least double the performance. However, it should be noted here that low-cost NVME hard drives use PCI-E 2 × channels, and high-performance NVME hard drives use PCI-E 4 × channels, so you can also see why all NVME hard drives have performance because of the price. Differences vary.

In the end, the question is whether to buy or not. If you are a serious gamer, an NVME SSD is a very good choice, and those who need to do design work, the larger the rendered file, the more powerful disks are needed. Performance, NVME hard drive is definitely a good choice. As for ordinary applications, a solid-state drive with SATA interface is very good!
