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.

The new PCIe generation doubles this upper limit from theoretically 8 GB/s to 16 GB/s - the speed in practice is around 7 (PCIe 4.0) or 14-15 GB/s (PCIe 5.0) due to the overhead. Further benchmarks will show how high the random read speeds are, which are important in practice. ADATAWhile 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/s, 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 1743Samsung&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/s 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. ![]() deutsche Version dieser Seite: CES 2022: Superschnelle PCIe 5.0 SSDs von ADATA und Samsung mit bis zu 14 GB/s |
