I have often read that Fedora Logical RAID has better performance characteristics than a “BIOS” or “FAKE” RAID. That may be true in some cases. Today I dispelled that myth in regards to Nvidia BIOS RAID0 versus Fedora Logical RAID0. The test results were identical. Results were obtained with the latest Fedora 12 updates applied, and EXT4 was the format of the file systems. Note that in all but one test of the series, the Nvidia C55 based ASUS P5N-E SLi E8400 system using a standard WDC 5000AAKS running Fedora 11 with an EXT3 partition outperformed an Evga 780i FTW QX9650 system using two WDC 5000AAKS in RAID0 AND using an Intel X25M SSD. Check the results at the link at the top of this article.
Nvidia “Fake” RAID0 identical in speed to Fedora 12 Soft RAID.
