Intel Smart Response Technology (select models only)
Intel® Smart Response Technology (SRT) is an Intel® Rapid Storage Technology (RST) caching
feature that significantly enhances computer system performance. SRT allows computers with an
SSD mSATA module to be used as cache memory between the system memory and hard disk drive.
This provides the advantage of having a hard disk drive (or a RAID volume) for maximum storage
capacity while simultaneously delivering SSD enhanced system performance experience.
If you add or upgrade a hard drive and intend to set a RAID volume, you must temporarily disable
SRT, set the RAID volume, and then enable SRT. To temporarily disable SRT:
1. From the Start screen, type Intel, and then select Intel Rapid Storage Technology.
2. Click the Acceleration link, and then click the Disable Acceleration link.
3. Wait for the Acceleration Mode to complete.
4. Click the Reset to Available link.
IMPORTANT: You must temporarily disable SRT when changing RAID modes. Make the change
and then re-enable SRT. Failure to temporarily disable this feature will prevent you from creating or
changing RAID volumes.
NOTE: HP does not support SRT with self-encrypting drives (SEDs).
