Superfast PCIe 5.0 SSDs from ADATA and Samsung with up to 14 GB/s

Superfast PCIe 5.0 SSDs from ADATA and Samsung with up to 14 GB/s

[15:53 mon,3.January 2022   by ]    

At the CES 2022 computer show, which kicks off on January 5, both Samsung and ADATA will unveil their first PCIe 5.0 SSDs, which nearly double the speed of the current PCIe 4.0 NVME SSD generation.

For example, Samsung&s PCIe 5.0 NVMe SSD PM1743 achieves a sequential speed of over 13 GB/sGB/s im Glossar erklärt and a write speed of 6.6 GB/sGB/s im Glossar erklärt on a system with Intel&s 12th generation Core i9-12900K CPU (Alder Lake), an Asus Z690 motherboard, and an Nvidia RTX 3080 according to Intel.

ADATA Project Nighthawk and Blackbird

For comparison: the fastest current PCIe 4.0 SSDs, such as Samsung&s SSD 980 Pro, have a maximum speed of 7.1 GB/sGB/s im Glossar erklärt and have thus already reached the upper limit of the PCIe 4.0 interface. The new PCIe generation doubles this upper limit from theoretically 8 GB/sGB/s im Glossar erklärt to 16 GB/sGB/s im Glossar erklärt - the speed in practice is around 7 (PCIe 4.0) or 14-15 GB/sGB/s im Glossar erklärt (PCIe 5.0) due to the overhead. Further benchmarks will show how high the random read speeds are, which are important in practice.


While Samsung&s new PCIe 5.0 SSD is aimed at the professional server market, ADATA will already (demonstrate) the prototypes of two PCIe 5.0 SSDs with capacities of up to 8 TB for professional consumers and gamers at CES www.adata.com/en/news/960. These are the "Project Nighthawk", which is equipped with a Silicon Motion SM2508 controller and offers sequential read/write performance of up to 14/12 GB/sGB/s im Glossar erklärt, and the "Project Blackbird", which is equipped with an InnoGrit IG5666 controller and offers read/write performance of 14/10 GB/s.

PCIe 5.0 is supported by the recently released Intel Alder Lake CPUs of the 12th generation including the corresponding chipset - but since their M.2 interface is only connected via PCIe 4.0 CIe, ADATS PCIe 5.0 SSDs only reach their maximum speed if they are directly connected via four PCIe 5.0 lanes using an expansion card via NVMe 2.0 protocol - however, this is only a stopgap solution until there is either a new interface standard or M.2 slots with CPU PCIe 5.0 lanes, which will possibly only happen in the next CPU generation.

Faster is hotter

However, the higher speed also brings disadvantages: for example, the power consumption increases almost proportionally with the bandwidth - it will therefore be around 14 watts for the PM1743 and will increase even more for the faster models in the future. Heat sinks - possibly even with their own ventilation - are therefore mandatory for such SSDs to be able to work at their maximum speed permanently without overheating.

Samsung PM 1743

Moreover, since the current M.2 standard has reached its limits, the industry is already working on a successor system, which should not only provide better signal quality, but also improve heat dissipation via the motherboard and possibly also allow even higher speeds by connecting to even more PCIe lanes, thus enabling further acceleration even before the introduction of PCIe 6.0 .

Samsung PM 1743

Samsung&s PM 1743 (with storage sizes ranging from 1.92 to 15.36 TB) will be launched to coincide with the summer 2022 launch of Intel&s first server CPUs with PCIe 5.0 support. The PM1743 uses optionally four PCIe 5.0 lanes (with 4 GB/sGB/s im Glossar erklärt each) in the form of 1×4 (single port) or 2×2 (dual port) enterprise interfaces to transfer data.


For video editing at least (grade of higher-resolution formats like 6K, 8K as well as RAW), higher mass storage bandwidths are always good news as they can avoid possible bottlenecks at work - be it when transferring data to and from an NVMe SSD or when using (multiple) GPUs to calculate effects.
