PCIe 4.0 is here and along with it, the first PCIe 4.0 devices are here as well. Those devices include PCIe 4.0 SSDs. These new SSDs are much faster due to them being able to utilize almost double the bandwidth of the older generation. So, if you’re looking for the best PCIe 4.0 SSDs released so far, then this is the place to find them. Let’s check them out!

Over the past few years, there have been multiple revisions of the PCI slot. There was the original, then PCIe 2.0, 3.0, and now 4.0. The main difference between them is speed. Each one of the new revisions can offer 2 times more bandwidth than its predecessor. Without any further ado, let us check the best PCIe 4.0 SSDs

  1. Sabrent Rocket PCIe 4.0 M.2

Sabrent 1TB Rocket NVMe 4.0 Gen4 PCIe M.2 Internal SSD Extreme Performance Solid State Drive (SB-ROCKET-NVMe4-1TB)
The Sabrent Rocket comes in at the size of either 1 or 2 terabytes. 1 TB is plenty of space for most people, but, if you’re going to do this investment, consider getting the larger version if need be.

Other than that, there is also the option of choosing to get it with or without a heatsink and we’d highly recommend getting it with one. After all, as mentioned above, PCIe 4.0 SSDs get rather hot and chances are that the Sabrent Rocket is no exception.

In terms of specifications, this SSD boasts speeds of up to 5 GB/s for reading and up to 4.4 GB/s for writing. To give you a point of reference, the average SATA SSD can only get up to about 500 MB/s.

However, those blazing fast speeds can only be reached on X570 motherboards. At the moment, they are the only ones who support the PCIe 4.0 slots. So, do keep that in mind.

The Sabrent Rocket can still be used on PCIe 3.0 slots. However, that will throttle down its speed to that generation, which is about 3.5 GB/s. And in that case, you may as well go with the PCIe 3.0 version instead to save some money.

  1. Gigabyte Aorus PCIe 4.0 M.2

GIGABYTE AORUS NVMe Gen4 M.2 1TB PCI-Express 4.0 Interface High Performance Gaming, Full Body Copper Heat Spreader, Toshiba 3D NAND, DDR Cache Buffer, 5 Year Warranty SSD GP-ASM2NE6100TTTD
This is a high-performance internal drive which is available in either 1 or 2 terabytes. It would be number one on this list if the price wasn’t weighing it down. The 2 terabyte version generally comes with a jaw-dropping price-tag.

Regarding the heatsink, we can’t help but worry a little bit about it. After all, this is a PCIe 4.0 SSD with higher performance and everything. So, it’s definitely going to need a bit of cooling.

And the thing is that the included heatsink doesn’t look like much. So, hopefully, Gigabyte either knows what they are doing, which is very likely, or you’ll need good, dedicated M.2 cooling in your motherboard. It is worth noting that this SSD features a full-body copper head spreader which is most likely why it doesn’t need such a large heatsink. But, that is probably why its price tag is a bit higher.

As for performance, we’re looking at 5 GB/s for reading speeds and about 4 GB/s for writing. It seems like most PCIe 4.0 SSDs are stuck at or around that read and write speed. Could be because of thermals, chip limitations, or a combination of both. But it is still a good improvement over PCIe 3.0 SSDs.

  1. Corsair Force Series MP600 PCIe 4.0 M.2

Corsair Force Series MP600 1TB Gen4 PCIe X4 NVMe M.2 SSD
Corsair is known for making some of the best high-end products in the tech industry and the Force Series MP600 is no exception. At the moment, this is one of the best PCIe 4.0 SSDs of 2019. In terms of size, you’re free to pick between a 1 TB version, and a 2 TB version.

The heatsink and build-quality look exceptional. And at this point, we need to mention that while you may be tempted to remove the heatsink and rely solely on your motherboard’s M.2 heatsink, Corsair recommends against this.

Performance-wise, the MP600 doesn’t differ too much from the other PCIe 4.0 SSDs. It can reach up to 4,950 MB/s when reading and 4,250 MB/s when writing.

Corsair has mentioned that this SSD is backward compatible with PCIe 3.0. But, an X570 board with PCIe 4.0 support will deliver the best results. That’s because the older generation of PCIe is just unable to provide the required bandwidth.

While we are at this subject, AMD has mentioned that certain X470 boards can actually support PCIe 4.0 with a BIOS update. However, the stability risk is a bit too high and that’s why we won’t be seeing it coming to anything else but X570 boards. Chipset limitations and such.
