Gradually, the main manufacturers of SSD
present their PCI Express 5.0 products and their absolutely crazy speeds.
ADATA yesterday, Samsung today, the year 2022 should therefore be the year of the switch from the SSD world to PCI Express Gen 5, even if this will undoubtedly concern very specific audiences first.
6th Generation Home Controller and V-NAND
By marketing its 12th generation of processors, Intel has above all laid the groundwork for several technical developments with the adoption of a new type of RAM – DDR5 – and the implementation of PCI Express 5.0.
The latter should logically be used by manufacturers of graphics cards like AMD and NVIDIA, but it is the designers of SSDs who, for the moment, are taking the technology head-on.
Samsung confirms that it designed the PM1743 an SSD primarily designed for corporate servers and exploiting the PCI Express 5.0 interface through a new in-house controller and sixth generation V-NAND.
Mass production in the first quarter of 2022
PCI Express 5.0 offers a maximum bandwidth of 32 GT / s, double that of PCI Express 4.0. There is no question of saturating the new interface straight away, but the PM1743 already promises top performance.
Samsung thus evokes speeds of 13 Gb / s in sequential read and, on average, 2.5 million IOPS in random read. The South Korean specifies that it thus improves respectively by 1.9x and 1.7x the performance recorded on the previous generation, in PCIe 4.0.
The write performance is much lower: Samsung speaks of a maximum of 6.6 Gb / s in sequential and 250,000 IOPS in random, but the gains observed compared to the previous generation are of a substantially equivalent level ( 1.7x and 1.9x).
Samsung also points out that the PM1743 will be available in capacities ranging from 1.92 TB to 15.36 TB and in two formats: the classic 2.5-inch and the EDSFF, less known to the general public. Samples are already being distributed to close partners of Samsung which is planning mass production in the first quarter of 2022.
