The SanDisk X210 is the high-end SATA SSD designed for the client computing, data center, and server markets. Based on 19 nm MLC NAND flash, it introduces a set of features and enhancements to support businesses that prioritize fast, consistent access to data, such as search engine and cloud storage providers and streaming media companies. Built to provide leading performance in read-intensive environments, the X210 also significantly reduces I/O bottlenecks and greatly improves random I/O performance and multi-stream capabilities.
At the heart of the X210 is a high performance controller and SanDisk's own 19 nm All Bit Line (ABL) architecture. All Bit Line architecture offers twice the parallelism of conventional Half Bit Line (HBL) architectures; increasing both performance and endurance.
The drive also supports a unique feature to improve random write performance and ensure a very positive user experience. Modern operating systems mostly access the storage device using small access blocks, with the majority being 4 KB access blocks. The small logical access blocks conflict with the physical block structure for the newer generation flash memory technology.
