Avoid the FastTraks. Most are FRAID (Fake/Free RAID), 100% software with
0% GPL drivers.
The SuperTraks are a "true hardware" microcontroller+DRAM solution with GPL drivers. Unfortunately, they use mega-yesteryear i960 microcontrollers not able to keep up with today's drives.
Thanks for the heads up
Is there any consideration driving RAID-5? For a majority of applications, RAID-0+1 tends to be better.
No, just another toy to play with. I'm currently looking a playing with Software RAID but would like to have H/W as well.
I prefer 3Ware Escalade 7506/8506 series cards for RAID-0+1. They use a 64-bit ASIC and SRAM (static RAM).
The 9500S series is still maturing, although they should eventually show outstanding performance. They add a large amount of DRAM to the existing ASIC+SRAM approach of the earlier Escalades.
I'm certainly liking what I have seen of the 3Ware card's so far. Their site lists quite a few distros as supported, including RHEL 3 which from a simplistic guess would also mean that Centos 3 (and possibly 4) would also be supported.
