Learn about the M.2 PCIe SSD standard

M.2 PCIe is the generation of SSD hard drives commonly used on laptops at the present time with many outstanding advantages over other hard drive standards such as M.2 or SATA. So let's join WebTech360 to learn about M.2 PCIe SSD standard!

1. What is M.2 PCIe SSD standard?

It was known around August 2014 when the famous SSD manufacturers began to market a completely different interface, initially abbreviated as NGFF (Next Generation Form Factor), later changed to M2.

Standard SSD M.2 have access speed SATA 3 is capped at 550 MB / s . However, when the data source to be read is too large, the M.2 standard is inefficient.

Therefore, SSD manufacturers have upgraded the old M.2 standard and named it M.2 PCIe (Peripheral Component Interconnect Express) which connects data directly to the motherboard.

M.2 PCIe is currently the most advanced SSD standard today with theoretical read and write speeds of up to 3,500 MB / s.

2. What are the advantages and disadvantages of the M.2 PCIe SSD?

Advantages

PCIe 3.0 has a storage speed of 985MB / s per lane, and since PCIe devices support 1x, 4x, 8x, and 16x lanes it can go up to 15.76GB / s . This is the speed that the SATA standard is difficult to get.

This means that a 16x lane PCIe SSD will be 25 times faster than a SATA SSD. Theoretically, but you won't see a consumer SSD with that many lanes. This is usually 2x or 4x, which is about 3.94GB / s.

Defect

Even so, you only realize the difference between PCIe and SATA when transferring files is huge. For example, with gaming laptops , if you want faster game loading speeds when opening or changing maps, both PCIe and SATA feel equally fast.

You only use your laptop to browse the web, use common tasks or those that only consume CPU and RAM, you will not notice too much difference between PCIe and SATA hard drives. But if your work regularly reads and transfers data, the life of the PCIe hard drive will be significantly affected.

If you need a hard drive with fast read speeds to share data, you should choose the M.2 PCIe, but if your budget is limited, the M.2 SATA standard will also be a perfect choice.
