Samsung is drafting a regulatory filing for its 990 PRO client-segment SSD of the next generation. The M.2 NVMe storage device will utilize PCI-Express Gen 5.
Two storage capacities have been identified thus far: 1 TB and 2 TB. Samsung will compete with flagship M.2 SSDs of Generation 5 driven by next-generation Phison and Silicon Motion controllers and 3D NAND flash chips with more than 144 layers. The drive replaces the 980 PRO, the company's current top Gen 4 SSD.
Harukaze5719 discovered that the Korean RRA (National Radio Research Agency) has published a list of forthcoming drivers. Samsung's model name submission includes "MZ-V9P1T0" and "MZ-V9P2T0." Existing Samsung 980 Pro PCIe Gen 4.0 SSDs are designated "MZ-V8P1T00" for reference. One might conclude that these are the next-generation Samsung 990 Pro 1 TB and 2 TB PCIe Gen 5 SSD devices.
Samsung has already released its first PCIe Gen 5.0 SSDs for servers, the PM1743, which delivers speeds of up to 13 GB/s (random read) and 2,500K IOPS (IOPS). The drives have capacities of up to 15.36 TB, however such absurd numbers should not be expected on consumer systems. We know that the next-generation PCIe Gen 5.0 SSDs will offer speeds of up to 14 GB/s and capacities of up to 8 TB, so we should anticipate the same from Samsung's storage options. We cannot confirm all features at this time, but Samsung's 980 Pro Gen 4 SSDs were among the best options for the PCIe 4.0 platform until just recently, when rivals began releasing their top-tier designs.
Update: confirmed. Samsung's 990 Pro appears on PCI-list SIG's of PCIe 5.0 SSDs, confirming the m.2 SSD's debut. The PM1743 server SSD is also included. The PM1743 reads 13 GB/s and writes 6.6 GB/s. The 990 Pro's write speed should improve. Apacer and Zadak just unveiled 13 GB/s read and 12 GB/s write PCIe 5.0 SSDs. Samsung hasn't released the 990 Pro.
Update (22/8): The 990 Pro was recently discovered in the PCIe 5.0 list, which looked to corroborate the SSD's debut. PCI-SIG is the organization that created the PCI(e) standard and maintains these lists of gear that comply with it. It is unknown why the 990 Pro is suddenly not PCI 5.0 compliant.
Update: (24/8): The 990 Pro is Samsung's latest SSD flagship. This new model uses 'older' PCIe 4.0, as just revealed.The 990 Pro's sequential read and write speeds are 7,450 and 6,900 MB/s thanks to Samsung's newest V-nand and proprietary controller. Random reads and writes are up to 55% quicker than the 980 Pro.
The new controller should make the 990 Pro 50% more efficient than its predecessor. It has a nickel-coated controller and a heat spreader, which improves temperature regulation.1 and 2 TB models are due in October for 190 and 360 euros. Next year, a 4TB variant will be available; no pricing is given. Samsung said SKUs with a heatsink and RGB lighting will come, but when or how much is unclear.
