128GB X300 SSD

New | Bulk Packaged

2.5-inch | SATA 6.0Gb/s
Low power, high performance, and reliability
Ideal for corporate PCs and notebooks, the SanDisk X300 SSD is built on industry-leading 1Ynm multi-level cell (MLC) NAND flash technology and incorporates advanced power management.

The X300 features support for the TCG Opal 2.0 and Microsoft™ Encrypted Hard Drive 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 charge while companies can seamlessly secure their data for their on-the-go employees.
The X300 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 of newer flash memory technology. To bridge this difference, the X300 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.

A performance throttling technique is used as a safety measure to protect the integrity of the data and prevent excessive heat dissipation. The X300 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.
