Every few months, we see news of those who are the new Fastest SSD on the market. In the last year and a half, this type of news has exploded thanks to the introduction of the PCIe 4.0 standard and the creation of controllers that can take advantage of all the bandwidth offered by this new standard. Now, PNY has launched the first PCIe 4.0 SSD that reaches the theoretical limit and practical of PCIe 4.0.


Specifically, we are talking about PNY XLR8 CS3140 M.2 NVMe Gen4 x4, announced this week by PNY. The company has SSD units at the forefront, and with this unit they have positioned themselves as the first to launch an SSD for individuals capable of reaching blazing speeds, being about 15 times faster than a conventional SATA SSD.

Up to 7,500 MB / s speed

Specifically, this SSD reaches speeds sequential readings of 7,500 MB / s, and 6,850 MB / s sequential write, far exceeding what other SSD drives on the market offer. The one that comes closest to it reached 7,400 MB / s, and was announced at the end of last year.

This great speed is also accompanied by great energy efficiency thanks to using a manufacturing size of 12 nanometers, allowing it to operate while generating less heat. By reading and writing information faster, usage time is reduced, which increases battery life, durability, and can offer higher performance for longer.

There will be two versions available: one with a massive aluminum heatsink and one without. It will be available in two capacities 1 and 2 TB, with a 5-year warranty. Form factor is M.2 2280, with protocol support NVMe 1.4. Therefore, it will be necessary to have a card compatible with PCIe 4.0, such as the X570. Thus, it will be necessary to have a Ryzen 3000 or 5000, or an Intel 11th Gen to be able to get the most out of it.

DirectStorage will make these SSDs worth buying

Unfortunately, its price has not been revealed, but it will be on sale from end of January 2021, so it won’t take long to find out how much it will cost us to get hold of this beast. Its price should be at least around 200 euros for the 1 TB version, for the 400 euros that the one of 2 TB. That is what the CS3040 model currently costs, with read and write speeds of 5,600 and 4,300 MB / s, so either it will drop slightly in price, or the new PNY will open the door to a new price range within the high-end SSD.

Currently, there is no real big difference in performance from using one SSD to another. If you create content, yes you will benefit from it, but if you are simply looking for speed for games or to open programs, there is hardly any difference between a SATA SSD, a PCIe 3.0 or a 4.0, since Windows has a big bottleneck in the form in which it manages the instructions. However, this will change from this year with DirectStorage, so you will be interested in having at least one NVMe SSD because games can finally get all the performance out of it with almost non-existent load times.
