WriteIoAggregateMinSize (Standard 8 Module Reference)
7/8/2014
Review the applicable Embedded Core modules and any examples for the WriteIOAggregateMinSize setting in Windows Embedded 8 Standard (Standard 8).
This setting specifies the minimum I/O size for write aggregation, in bytes.
The default value is 1048576 (1 GB) for eMMC volumes; otherwise, the default value is 0.
This setting works with other settings in the SecureStartup-FilterDriver component to optimize BitLocker settings for devices with hardware architectures such as System on a Chip (SoC). Do not use these settings for standard 32-bit or 64-bit hardware architectures. For specific guidance on using these settings, contact Microsoft.
