Thanks to CTOnews.com netizen OC_Formula for clue delivery! CTOnews.com September 1 news, last week, Samsung officially released the Samsung 990 PRO PCIe 4.0 SSD, the official said that the 990 PRO fully balanced the requirements of high speed, high energy efficiency and high reliability, using 3D TLC (3bit) particles and a new self-developed master, sequential read and write speeds of up to 7,450 MB/s and 6,900 MB/s respectively, random read and write speeds of up to 1,400 K and 1,550 K IOPS respectively, Compared to the 980 PRO, its random read and write performance is improved by 55%.

Samsung 990 PRO series products use PCIe 4.0 interface, and the industry generally believed that this product will adopt PCIe new standard PCI Express 5.0, which can improve the transmission speed, but in fact Samsung Electronics still maintains the PCI Express 4.0 standard of 990 Pro.

In response, Samsung Electronics explained that "this is not a product development or technical issue, but a judgment based on market conditions." "

Samsung says the newly designed SSD controller significantly improves energy efficiency by up to 50% compared to the 980 PRO. In addition, the 990 PRO adds nickel coating to the controller and uses a label heat sink on the hard disk to ensure stable heat dissipation, while the 990 PRO (thermal version) will also provide an additional layer of heat sink and support RGB light texture.

PCI Express 5.0 is a new standard released by PCI-SIG in May 2019. Its transfer rate has doubled again compared to 4.0, which now transfers up to about 2 GB / s per lane, while Micron's previously demonstrated 5.0 solid-state sequential reads and writes can reach 10 GB / s.

CTOnews.com understands that Samsung 990 PRO will be available globally in November this year for six consecutive years, with a 1TB model for $179, a 2TB version for $309, a model with a heatsink for $20, and a 4TB model next year.
