Introduction Offloaded Data Transfers (ODX) is a feature in Microsoft Windows operating systems that was introduced in Windows 8 and Windows Server 2012. ODX is designed to improve the efficiency and speed of data transfer operations, especially in scenarios involving large files and remote storage systems. It allows for the offloading of data transfer operations to the storage hardware, reducing the load on the CPU and improving performance. Key aspects of Offloaded Data Transfers (ODX): Offloading: ODX offloads certain data transfer tasks from the host system (the computer initiating the transfer) to the storage array or storage device itself....

RAID Description RAID is an array, or group, of multiple independent physical drives that provide high performance and fault tolerance. A RAID drive group improves I/O(input/output) performance and reliability. The RAID drive group appears to the host computer as a single storage unit or as multiple virtual units. I/O is expedited because several drives can be accessed simultaneously. RAID Benefits RAID drive groups improve data storage reliability and fault tolerance compared to single-drive storage systems....
