Samsung Electronics just announced volume production of SSDs that support the SATA 3.0 (6Gb/s), with new high-performance PM830 SSDs up to 512 GB densities. The new drives are expected to replace SATA 3Gb/s-based SSDs by year-end.
“Samsung’s new line up of advanced SSDs will raise the performance bar to the next level for ultra-slim notebooks and tablets and accelerate growth of the market for high-performance SSDs,” said Wanhoon Hong, executive vice president, memory sales & marketing, Device Solutions, Samsung Electronics. “The industry is expected to quickly embrace SATA 6Gb/s-based SSDs, which also will help increase market interest in 256GB and higher densities significantly,” he added.
Samsung claims that its new 6Gb/s SSDs shortens system boot-up time to about 10 seconds, while its high-performance allows users to download up to five DVD video files in less than a minute. The drives also feature an AES 256-bit encryption algorithm
The new SSDs utilizes Samsung’s 20 nm class 32 Gb MLC NAND memory chip incorporating the toggle DDR interface with a proprietary NAND controller. This allows Samsung's new SSD to boast sequential read speeds of 500 megabytes per second (MB/s) and sequential write speeds of 350MB/s.
Samsung’s SATA 6Gb/s SSDs are available in 512GB, 256GB and 128GB densities.
The difference is 10NM. :)
It lets them make more chips per wafer. From the consumer perspective, you might see a price drop if they can keep the yield up.
So higher speed but shorter life. However, for the average SSD user that life spans is still many years. Only the heaviest of SSD write cycle users will find the shortened life as a problem.
Sadly it also traditionaly have resulted in less erase cycles per cell
