ATA RAID has been a passion of mine since 1998 when I had eight 2 GB Western Digital ATA33 disks and wanted to get them working together in one system. At the time there was only one option: the Promise FastTrak. It was later renamed the FastTrak33 to come in line with the rest of their product line, but it was a thing of beauty. It was then that I entered the world of RAID. To learn about it was to know the SCSI controllers and devices that dominated the field, and only in high end workstations and servers.
So much has changed since then that it’s hard to believe; almost every motherboard today comes with some form of onboard RAID, and the players have multiplied as well. Even Intel is building RAID into it’s next generation chipsets of 2003.
It’s been the steady march of progress for ATA RAID that has kept me interested. In 2001 I reviewed two ATA RAID controllers that broke new ground with RAID 5. This was the only thing that was keeping this fledgling technology from entering the enterprise market. Below are links to my ATA RAID 2001 project. ATA RAID 2003 is well inderway with two new cards reviewed and some classic cards re-benchmarked.
