Samsung is the SSD slayer.
Samsung’s efforts in the SSD market really have been quite remarkable. Ever since unveiling it’s 840 series in 2012, the company has absolutely dominated the consumer SSD market, delivering blitzkrieg speeds at affordable prices. The new 850 Pro aims to lengthen the companies lead, and appears to have accomplished its mission.
Key to the new drive is the use of 3D V-NAND ash memory, a proprietary type of memory developed by Samsung where the memory is layered both horizontally and vertically. This is powered by the existing MEX controller found in other Sammy drives, but the speed has been bumped up by 100MHz, now maxing out at 400MHz. A SATA 3 interface provides the interconnect between the drive and the motherboard, which is limited to a maximum speed of 6Gb/sec, which is fast becoming the bottleneck in today’s consumer SSDs.
