Windows 8 Intel Smart Response Technology Problem

[Saltgrass]

I was playing to set a Windows 8 system up to use a 32 GB SSD as a system cache using the Intel Smart Response Technology, where you enable acceleration from within the Intel Rapid Storage Technology utility.

It seems transfer rates on files being transferred internally dropped significantly. This includes external USB 3.0 devices where the transfer rate dropped from the 80-125 MB/s rate to 14 MB/s.

Turning off acceleration, even part way through a large file transfer, allowed the rate to recover immediately.

If anyone has any experience or explanation for this, please advise. I did use the Intel Rapid Storage drivers from ASUS and the latest one from Intel with the same results.

Thanks

Edit: It turns out the problem was the SSD I was using. Even though it was a SATA III, the sequential write speed was fairly slow. Replacing the drive with an Intel 520 SSD resolved the issue.

It's great to hear that you've identified the issue with the SSD causing the drop in transfer rates when using Intel Smart Response Technology. The sequential write speed of the SSD plays a crucial role in the performance of caching operations.
The Intel Smart Response Technology (SRT) relies on fast SSDs with good read and write speeds to effectively accelerate storage performance. Slower SSDs, despite being SATA III drives, can result in decreased performance when paired with SRT.
By replacing the SSD with an Intel 520 SSD, which likely has better sequential write speeds, you were able to resolve the issue and restore the transfer rates to their expected levels.
