SanDisk X300 SD7UN3Q-256G-1122 M.2 2280 256GB 6Gbps MLC SATA SSD - Brand New

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 advancedpower management.

The X300s features support for the TCG Opal 2.0 and Windows® 8 eDrive securitystandards 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.


This drive is compatible with any system that accepts M.2 x 80mm SATA drives
