The San Disk X210 is our high-end SATA SSD designed for the client computing, data center, & server markets. Based on 19nm MLC NAND flash, it introduces a new set of features & enhancements to support businesses that prioritize fast, consistent access to data, such as search engine & cloud storage providers & streaming media companies. Built to provide leading performance in read-intensive environments, the X210 also significantly reduces I/O bottlenecks & greatly improves random I/O performance & multi-stream capabilities. ATA command set ACS-3 NCQ support up to queue depth = 32 Support for TRIM S.M.A.R.T. feature supported Advanced Flash Management Support for thermal throttling Tiered caching—volatile & non-volatile cache Performance At the heart of the X210 is a high performance controller & San Disk’s own 19nm All Bit Line (ABL) architecture. All Bit Line architecture offers twice the parallelism of conventional Half Bit Line (HBL) architectures; increasing both performance & endurance. The drive also supports a unique feature to improve random write performance & ensure a very positive user experience. Modern operating systems mostly access the storage device using small access blocks, with the majority being 4KB access blocks. The small logical access blocks conflict with the physical block structure (>1MB) for the newer generation flash memory technology. To bridge this difference, the X210 employs three storage layers: Volatile cache
- DDR DRAM cache n Cache
- A non-volatile flash write cache Mass storage – MLC NAND flash The n Cache is used to accumulate small writes (called segments) at high speed & then flushes & consolidates them to larger MLC sections of the NAND flash memory array. Power Management The X210 employs DEVSLP SATA low power mode, which further reduces the device’s power consumption in the IDLE state. This is important as extending the time between battery charges has become critical in mobile devices. DEVSLP enables the device, & optionally the host, to completely shut off their SATA PHY, resulting in much lower power consumption compared to Slumber SATA lower power mode.
