My system has a SATA 2 controller. The docs say it will work with SATA 2, and its installed and beginning its caching process. My question is estimating “the hit” I take for SATA 2 versus SATA 3.
SATA 2, delivers 3 GB per second and SATA 3 at 6GB per second.
The specs say that the SSD cache delivers 480MB/s from it to the motherboard
If so 480MB/s * X 8 bits per byte = 3.8GB/sec
If that’s true, and my system can only move 3.0GB/s, I take a 20% hit on the advertised 4X improvment on 7200RPM 500GB SATA drive? .8 / 3.8 = 21%
If that’s true, I’ll be looking more in the neighborhood of 3x improvement? What does SanDisk see when testing the product?
