PCIE SSDs are SATA III SSDs



[ad_1]

SSDs have become a fundamental component in every current computer. The drop in prices they experienced has enabled them improve attractivenesseven in the face of consumers with very limited budgets.

It is true that there is still no real parity in terms of costs per gigabyte when comparing solid-state solid-state hard drives, but This is compensated by the advantages the first in comparison with the latter:

  • Increased read and write speed.
  • Lower consumption and heat production.
  • Silent operation
  • High strength and good shelf life.

This is not a new topic in this manual for SSDs We saw all your keys, We also confirmed that this type of storage unit can significantly improve the gaming experience.

However, when we talk about SSDs, we can make two big differences, depending on the interface used. Standard models are those that work through SATA III, while the most advanced models use iPCIE x4 interface and NVMe protocol.

The differences that exist between the two species are very important. In the case of SATA III models, we can see that on average, the speed of successive reading 550 MB / s, in sequential writing reach approximately 520 MB / s. In the case of PCIE x4 SSDs, these numbers are raised to 3.500 MB / s and 2.500 MB / s.

From a direct comparison we can see that the distance between one and the other is large. However, in practice, the differences are not as marked as you would expect. We have already seen this in this article, dedicated to the start-up time of Windows 10, which we also discussed in this analysis in the chapter on loading times in games.

It is clear that most of the current applications and operating systems are not ready Really take advantage of the potential offered by PCIE x4 SSD, although in any case offers a clear improvement in performance compared to SATA III units.

The price drop which affects the NAND Flash memory sector, has enabled PCIE SSDs to become cheaper, which, according to Apacer Technology president CK Chang, is that type of unit is transmitted to SATA III versions.

The Executive Body is convinced that PCIE SSDs will eventually become the dominant unit for storing the general consumer market end of 2019, with a quota of around 50%. This is not a misconception, especially if the price of NAND Flash memory continues to fall in the coming quarters.
