Is PCIe 4.0 worth it for SSDs? If you want the absolute fastest drives available, then PCIe 4.0 SSDs are the way to go. They're quicker than any PCIe 3.0 drive and will make large file transfers for such things as video editing lightning fast.
It is worth the upgrade to PCIe 4.0 for gaming if you: Use the fastest NVMe storage devices for loading games, which will make use of the speed. Have a PCIe 4.0 graphics card, which may see a slight performance improvement. Want to future-proof your system.
Short answer: No. Longer answer: Unless you've got leftover budget and a good reason to burn it, PCIe 4.0 isn't likely worth buying into for a gaming system right now. For gaming, few graphics cards support PCIe 4.0 right now.
Not unless you're doing something like 4K+ video editing. If you're just using it for OS/software then you probably won't even notice a difference between a SATA SSD and a PCIe 3 x4 SSD. For the vast majority of people, no, at least not right now.
If you want the absolute fastest drives available, then PCIe 4.0 SSDs are the way to go. They're quicker than any PCIe 3.0 drive and will make large file transfers for such things as video editing lightning fast. They will also be prepared for the future of gaming.
But while PCIe 4.0 setups outperform 3.0 in synthetic benchmarks, the real-world benefits for gaming are currently minor. Some tests suggest that even running games in 4K with current graphics cards won't saturate the bandwidth of a PCIe 3.0 x16 slot.
NVMe will be the protocol of choice for the next generation of storage technologies such as 3D XPoint. PCIe 4.0 refers to the fourth generation of PCIe interface which has double the bandwidth (64GB/s for a x16 slot) compared to PCIe 3.0 (32GB/s for a x16 slot), which is the usual improvement between PCIe generations.
The main benefit of PCIe 4.0 SSDs being faster not only gives quicker loading times in some games, but it also translates to a much snappier operating system. You can expect instantaneous boot times with the latest NVMe drives if it houses your Windows, Linux, or macOS and fast loading of programs.
A PCIe 3.0 NVMe SSD will work in a PCIe 4.0 M. 2 motherboard slot at PCIe 3.0 speeds. PCI-Express versions are backward and forward compatible, meaning that you can use a PCIe 3.0 storage device in a PCIe 3.0 or PCIe 2.0 system.
The specifications for PCIe Gen 5 were officially announced back in 2019. As for the compatible peripherals, they're expected to hit the shelves later this year. As of now, only Intel's new Alder Lake CPUs and compatible motherboards have PCIe 5.0 support.
Like PCIe 3.0, PCIe 4.0 is forward and backward compatible. However, if you connect a PCIe 3.0 card to a PCIe 4.0 slot, the card will perform to the PCIe 3.0 specs.
PCI-Express versions are backward compatible, meaning that you can use a PCIe 4.0 graphics card or storage device on a PCIe 3.0 or PCIe 2.0 system.
Only the latest motherboards from Intel and AMD such as those featuring AMD X570, AMD B550, Intel Z590, Intel B560, Intel H570 chipsets supports V4. 0 NVMe M.
Rtx 3070 can't run Pcie 4.0.
We recommend a minimum of 8 PCIe Gen 4 lanes per physical x16 slot on the motherboard for a four-GPU build. You may use fewer GPUs and populate the empty PCIe slots with storage or network cards, depending on your requirements.
PCIe 4.0 enables a more robust equalization. In term of performance, with PCIe 4.0, throughput per lane is 16 GT/s. The link is full duplex, which means the data can be sent and received simultaneously à Total Bandwidth: 32GT/s.
SSDs have a clear advantage with faster access through the PCIe serial bus standard. NVMe was built from scratch as a new way to efficiently access storage devices that are specifically built with non-volatile (flash) memory – SSDs. NVMe enables a faster interface for leveraging the speeds that SSDs are capable of.
Not only does NVMe deliver better performance, but it is also highly compatible. There is now only one software interface standard for manufacturers to adhere to, so they don't have to write their own.
PCIe SSDs are faster than SATA SSDs.
In a nutshell, right now PCIe 4.0 does little to improve performance with the RTX 3080. It's possible that could change with future games, but for now it's a non-issue.
What does PCIe 4.0 do? Like other generations of PCIe, PCIe 4.0 interfaces with your computer's motherboard to facilitate the high-speed transfer of data from graphics cards, NVMe SSDs, RAID cards, and other expansion cards.
While there's less bandwidth for multiple next-generation high-speed storage and graphics card setups with B550 compared to X570, it does deliver enough PCIe 4.0 lanes for the typical setup of a single speedy boot drive and graphics card.
This test will tell us the bandwidth achieved to see which one will give us the faster data transfer during the game loading time. PCIe gen 4 was able to reach a bandwidth of 23.25GB/s whereas the PCIe gen 3 was only able to reach 14.31GB/s. That is a 39% benefit if you were to use PCIe gen 4 rather than PCIe gen 3.
PCI Express supersedes SATA as the latest high bandwidth interface. Entry-level PCIe SSD speeds are two to three times faster than the older generation of SATA 3.0 SSDs mainly due to the number of channels contained by each to transfer data (roughly 10 for SATA and 25 for PCIe).
