M.2 NVMe SSD Purchase Precautions Xiaobai Needs to Know Most


M.2 SSD NVMe is currently main choice of SSD, and laptop users can only select this type of SSD. So does it make sense to pay attention when buying M.2? NVMe SSD? Today, I will share with you how to buy and buy M.2 NVMe SSDs.

M.2 NVMe SSD Purchase Precautions Xiaobai Needs to Know Most

Confirm board

Although M.2 interface on motherboard is already a standard configuration, M.2 NVMe SSDs cannot be used on motherboards with M.2 interfaces. The main reason is that interface channels are different. Currently, all new motherboards support both SATA and PCI-E channels, but some motherboards may only support one of them, so this needs to be confirmed. The NVMe protocol requires PCI-E channels.

Besides, even though it is an M.2 interface, there are four types of M.2 interface lengths, namely 2242, 2260, 2280 and 22110, so when choosing an M.2 solid state interface, please note which length is supported by motherboard, otherwise it cannot be installed after purchase.

Meet brand

Solid-state drives come in different brands. It's hard to say which brand has best quality, but big brands should have more guarantees than smaller ones. Quality is not good enough, data is subject to loss.

Don't go cheap

PCI-E is not necessarily fast

While an NVMe M.2 SSD with a PCI-E link can take full advantage of read and write benefits, it depends on situation when using a PCI-E link. One is to look at basic control of SSD itself, and other is to look at what PCI-E channels interface supports. As shown in figure below, speed gap between different PCI-E levels is very large.
