Product information: X300s 128GB M.2 SATA 6Gb/s Solid State Drive (SD7UN3Q-128G-1022)Ideal for corporate PCs and notebooks, the SanDisk X300s SED1 (Self-Encrypting Drive) is built on industry-leading 1Ynm multi-level cell (MLC) NAND flash technology and incorporates hardware-based full disk encryption and advanced power management.
The X300s features support for the TCG Opal 2.0 and Windows® 8 eDrive security standards and a SATA DEVSLP low-power mode that is compatible with Microsoft® InstantGo. Users will appreciate greater productivity with more useable hours per battery charge2 while companies can seamlessly secure their data for their on-the-go employees.
The X300s uses a tiered caching structure to improve random write performance. Modern operating systems typically access the storage device using small 4KB access blocks. These small access blocks conflict with the physical block structure (>1MB) of newer flash memory technology. To bridge this difference, the X300s employs three storage layers: Volatile cache - DDR DRAM cache, nCache™ - A non-volatile flash write cache, Mass storage – MLC NAND flash.
The nCache™ write cache is used to accumulate small writes at high speed then flush and consolidate them into the larger MLC section of the NAND flash memory array.
The X300s SED seamlessly encrypts the drive data on the fly using hardware-based 256-bit AES encryption. It supports the following industry-standard security specifications: ATA Security Feature Set, TCG Opal 2.0, Microsoft® eDrive (TCG OPAL 2.0 + IEEE 1667)
A performance throttling technique is used as a safety measure to protect the integrity of the data and prevent excessive heat dissipation. The X300s employs an on-board thermal sensor to monitor the SSD’s critical component temperature. If it exceeds the normal range, drive performance is reduced until the temperature decreases to an acceptable level, at which time full performance is restored.
