技術 機能
Enhanced Power-Loss Data Protection Enhanced Power Loss Data Protection prepares the SSD for unexpected system power loss by minimizing data in transition in temporary buffers, and uses on-board power-loss protection capacitance to provide enough energy for the SSD firmware to move data from the transfer buffer and other temporary buffers to the NAND, thus protecting system and user data.
Hardware Encryption Hardware encryption is data encryption done at the drive level. This is used to ensure that the data stored on the drive is secured from unwanted intrusion.
High Endurance Technology (HET) High Endurance Technology (HET) in SSD's combines Intel® NAND Flash Memory silicon enhancements and SSD system management techniques to help extend the endurance of the SSD. Endurance is defined as the amount of data that can be written to an SSD during its lifetime.
Temperature Monitoring and Logging Temperature Monitoring and Logging uses an internal temperature sensor to monitor and log airflow and device internal temperature. The logged results can be accessed using the SMART command.
End-to-End Data Protection End-to-End Data Protection ensures integrity of stored data from the computer to the SSD and back.
Intel® Smart Response Technology Intel® Smart Response Technology combines the fast performance of a small solid state drive with the large capacity of a hard disk drive.
Intel® Rapid Start Technology Intel® Rapid Start Technology allows quick system resumes from the hibernate state.
Intel® Remote Secure Erase Intel® Remote Secure Erase provides IT administrators a secure method for remotely wiping an Intel SSD from a familiar management console when retiring or repurposing a system. This allows for immediate re-use while saving administrative time and costs.
