Select disorder! Solid state upgrade M.2 or SATA?

Xiao Bian has a bad news and a good news. Let's talk about bad news. During the dual 11s, there was hardly any price cuts for SSDs. Let's say good news. The price trend of SSDs is actually downward. Today, there is a small partner can not be reconciled, said that during the double 11 want to enter the solid state, but the price has almost never changed, but there is still this demand, asked Xiaobian have no recommendations, simply talk about the selection of SSD today.

Interface is different

SATA interface: SATA interface is the old interface, SATA stalled in the 3.0 version, the standard design of the maximum bandwidth of 6Gb / s, the actual transfer speed of 600MB / s. Nothing to say, the most basic and original interface, there is no doubt that SATA is the best universal, almost all devices support this interface. It should be noted that if you do not talk about SSDs, the SATA 3.0 standard interface will continue to exist. Don't forget that the actual transmission speed of mechanical hard drives is still far from the theoretical upper limit.

M.2 interface: It was originally used to replace the MSATA interface (mini version of the SATA interface), there are currently two versions, one is to continue to use the SATA standard, the maximum speed does not exceed 600MB/s, the other The use of NVMe standard PCI-E 3.0 4x bus, the performance is extremely powerful, you must know that PCI-E 3.0 4 × can provide the maximum 32Gb / s bandwidth, 4000MB / s transmission speed! Note that the main advantage of the M.2 interface is its small size and excellent performance. It is widely used in laptops, ultrabooks, and other portable devices.

U.2 interface: Compared to the M.2 interface, the U.2 interface should only be regarded as the "successor" of SATA. Currently, there are relatively few U.2 interface SSDs, and there is still a long way to go before it matures. . In fact, the basic features of U.2 are the same as those of M.2 (Using a riser card can be changed from M.2 to U.2), and also using the NVMe standard, PCI-E 3.0 4x bus, different places. The U.2 interface can also support 3.3V/12V dual voltage instead of the M.2 3.3V single voltage. Of course, U.2 is much larger than M.2.

The old machine new machine focuses on different

Upgrade solid-state hard drives, price factors Xiaobian first talk about, talk about choice, this is the focus of today's small partners asked questions. Let's talk about the old computer, Xiao Bian recommended SATA interface hard drive, although the performance than the M.2 interface (NVMe standard) solid-state hard drive, but wins in better compatibility, a wide range of applications, and the old machine is not so expensive hard drive is not Particularly cost-effective, this upgrade program, focusing on or more to see the cost-effective as well.

New computer expansion SSDs, especially notebooks and desktops purchased in the past year, Xiaobian strongly recommend the purchase of M.2 interface NVMe standard SSDs, performance worthy of every penny you spend! As a result, there is no need to consider upgrading before the computer is retired (over 240GB capacity). Pay attention! If you can't tell whether your computer supports NVMe standard, you can report your own computer model or motherboard model (DIY) to the merchant. The merchant can help you to judge.

As for MSATA, it is mostly used on notebook computers. In particular, older products are only equipped with MSATA interface hard disk drives. There is no M.2 interface at all. This interface only uses industrial control equipment, and Xiao Bian also looks at a certain treasure. Almost all second- and third-line brands and even disassembled second-hand goods, do not be good, or honestly buy a solid state SATA interface.
