Gigabyte i-RAM Review 4/7
Bluetooth 26 Sep 2005

Benchmarks

In our test, we installed the card onto a 945P system running 1G Corsair DDR2-533 modules. CPU used is a Intel 820D Dual Core with a 6600GT graphics card. HDD used is Hitachi 80G SATAII and Seagate 7200.7 SATA I(NCQ) HDD. WINXP is installed on Seagate HDD while the comparison is done for the SATA II hitachi against the i-RAM using Sisoft sandra 2005 lite file benchmarks, HDtach and PCmark2004, 2005

Below are the results.

HDtach

As we only use 4 x 256 MB modules, the i-RAM is sized around 1GB. From the chart below, we can see that the JMicron controller performs pretty well as an interface to the SATAII interface on mainboard. A burst speed of 136.6MB/s is recorded. Random Access time is amazingly at 0.1ms (no rotary parts). CPU utilisation is at 7%+/- 2% which is a bit higher than i expected.

Sandra 2005 Lite File Benchmarks

We tested the SATA II HD and i-RAM using Sandra and the results are very clear. The performance of i-RAM is even higher than that of a 3.5" 2xRAID 0(73G) array.
