Internal 4-Way SATA RAID For The XPC A Concept Study
(Review by MS, April 20, 2003)

System Assembly

One of the sore points of SATA has been the supply of power connectors. The salvation came in form of the good folks at Molex who were friendly enough to send us a small contingent of those rare specimens but the next problem turned out that the PSU used in the SB52G2 does not have enough connectors either. There is the possibility of using Y splitters but but those will clutter up precious space. So, out with the soldering iron to build a custom power harness. It looks a bit crude but how much can you ddo wrong, as long as you can count up to four.

The "space saver" harness and the four data cables make the place look more crowded than it really is. There are still three connectors left for CD/DVDROM, a parallel HDD (for ghosting or transfer of installation files / downloads) and the floppy disk that is needed during installation to get the Promise drivers into the installation.

In many ways, the entire setup was reminiscent more of working on a car engine with the red ignition cables than on a RAID setup.

All cables are hooked up to the Promise FastTrack S150 TX4 connector and it still looks neat. There are shorter cables available, matched colors and all kinds of improvement that could have been done to further improve the looks of the setup but this is already almost too good to hide it: Four disks of 40GB each for a 160 GB 4 disk RAID 0, 2 x 1 GB of DDR, how much space would have been required for this only last year?
