As you can see, the NAND price continues to fall in the past months. This is an important factor that will drive the PCIe SSD to take up about 50% market share by the end of 2019. In the following content, I’ll discuss more details about the market share of PCIe SSD and I will compare it with the SATA drive.

In the past, upgrading RAM is the most common and least expensive way to improve computer performance. With the increase of memory prices and the popularity of SSD, upgrading PC with an SSD becomes a better choice to fasten the speed & improve performance. Thus, the SSD market share is growing.

PCIe SSD Market Share Witness a Rapid Growth

According to statistics, the PCIe SSDs are becoming more and more popular since its release. In 2019, the market share growth is fierce. What’s the root reason? It is definitely because of the sharp reductions in NAND flash prices. To be precise, it is estimated that the PCIe SSD market share will be close to 50% by the end of 2019.

PCIe SSD market

Indeed, the SSDs which uses all the bandwidth that offered by PCIe will become more and more popular among PC towers. All in all, 2019 is regarded as the year when a strong competitor appears to threat the position of SATA SSDs in the market.

Why PCIe SSD Market Share Changes

As I have mentioned before, the most direct reason for the rapid growth of PCIe SSD market share is the sharp price reductions in NAND flash (which is used in SSDs). In the first quarter of 2019, the unit prices for 512GB PCIe SSDs are falling by 11% mainly due to the NAND oversupply. The prices for the 256GB drives are also dropped. Besides, the price of the drives with a higher capacity from 512GB to 1TB will also witness a decrease as time goes by. (As a matter of fact, there’s also a reduction – about 9% – in the prices for SATA drives.)

Due to the changes, manufacturers are set out to make up new plans for lucrative enterprise and data center use cases. Besides, the adoption rates among OEMs for inclusion in computers are prompted since the cost client SSDs is reducing.


In general, there are two ways to connect SSD with computer: through a SATA connector on a 2.5 inch drive or through a PCIe on an NMVe port. A faster speed will be provided by NVMe because of the using of PCIe ports. That’s an important reason why people choose PCIe SSD over SATA SSD.

What PCIe and SATA share in common?

  • The speed of PCIe SSD and that of SATA SSD are much faster than the common HDD.
  • Both PCIe SSD and SATA SSD can be used conveniently in M.2 form factor.

PCIe SSD vs. SATA SSD: Which Is The Better One For You

According to Digitimes, the 2.5-inch SATA SSD will withdraw from the stage of history gradually. The obvious improvement in 3D NAND production contributes a lot to the appearance of drives with faster speed and higher capacity.


All in all, the average selling prices for consumer PCIe 3.0 x2 SSDs (which are suitable for notebooks, not desktops) are low. This makes it more appealing to major OEMs. After all, the numerous enthusiasts are fond for NVMe all these years. Yet, you need to realize the fact that once the PCIe drives become a better choice for even moderately powered office workstations and personal laptops, they really go through rapid development.

The increasing PCIe SSD market share requires the enhanced SSD controllers. This draws much attention of the major OEMs. It is reported that many OEMs (such as Silicon Motion and Phison) are getting down to the enhanced PCIe SSD controllers in order to take advantage of emerging markets. Lately, the Micron is working on building its first in-house controller in the Micron 2200 SSD product (which is the entry-level NVMe drive).
