Hello,
We would like to inform that the Intel® Solid-State Drive Data Center Tool contains a firmware update for the Intel® SSD 750, the new firmware improves the Boot time of this drive significantly. Please keep in mind that even with the improvements, the boot time of the Intel® SSD 750 series may take longer than SATA drives, primarily due to how long it takes to initialize PCIe* devices. Once the 750 is in operation, it far exceeds the performance of SATA SSD's.
The new firmware release will also be available in upcoming versions of Intel® SSD Toolbox and Intel® Firmware Update Tool."
