If we talk about storage unitsWe must talk about Samsung, a manufacturer that offers solutions for all types of devices, from computers to mobile devices to servers and many others. Far from being satisfied with the privileged position it enjoys in this industry, this Korean company continues to focus its efforts on improving the capacity and performance of this type of units.
Last April, Samsung announced that it was working to start production of flash memory V9 QLC 9th Generation 280 layers that offer higher density and performance compared to products based on the same technology from other manufacturers.
This new type of next-generation memory takes advantage of Channel Hole Etching technology to pack a greater number of layers than the rest of the industry using a dual stack design which started to be implemented in 9th generation TLC memories.
Higher capacity, faster and cheaper SSDs
With this dual-stack design, 9th generation QLC V9 memory is 86% denser than previous generation QLC V-NAND memory, and improved data retention technology increases performance by 20% and read/write speeds by up to 60%.
But these new SSD units are not only capable of offering greater storage capacity with better read and write speeds. Thanks to this technology and the Low Power function available on these units that can be enabled or disabled, energy consumption is also reduced by reducing the voltage required by the NAND units so that they only send the necessary information, thus reducing consumption by 30 and 50%.
This type of Samsung memory has a storage density of 19.5 GB/mm2 distributed in 280 layerswhile YMTC memories with QLC technology have a density of 20.63 GB/mm2 in 232 layers. In this way, it offers 33% higher performance than YMTC memories operating at 3.2 Gbit/s.
With this technology, everything indicates that Samsung will be able to create SSD units with a higher capacity than the current one. 50% cheaper. If this means that an 8TB PCIe x4 SSD block will not cost more than 1,000 dollars as it currently does or 500 dollars per block SATA III SSD drive
The price of an 8TB hard drive varies between 150 and 200 dollars for models intended for NAS devices, a significant price difference that not everyone can or is willing to pay, although they offer a much lower read and write speed than SATA III SSDs and PCIe M.2 SSDs.
Samsung’s future plans include expanding production of this type of memory so that it reaches the largest number of users through PCIe M.2 SSD for home use, UFS disks for mobile devices and not forgetting storage disks for servers U.2 SSD which has a larger form factor.
When will these cheaper SSDs hit the market? If everything goes as Samsung plans, it is likely that by 2025 we will see the fruits of this new technology reflected in prices.
