I'm at wits- and info- end trying to pick a discrete workstation RAID card. Up to the US$400 level anyway.
Up until recently, I'd narrowed it down...mostly to Adaptec.
+ Adaptec 5405: Fast, stable, but runs really hot.
+ Adaptec 2405Q: The above without the heat, plus an SSD to speed things up. Possible vapor. No reviews; just fluff.
+ Adaptec 6405: 6 Gb/s; the "new" Adaptec made by a different company. Plus, Vaporware until 3/2011.
LSI seems to have some decent stuff, maybe, but no RAID10 options.
Areca seemed to have some boards that kicked butt...2 years ago...by pulling RAID-0 on reads and RAID-10 on writes. Sweet, but I'm not sure that edge exists anymore. Maybe that's the common algorithm now.
But what gets my goat is that it is almost impossible to find hard CURRENT numbers on any of these controllers' performance at the various RAID levels; that is, the articles that do have that info are 2-3 years out of date. Given that even a firmware update could radically change the performance of any controller, the older results are likely little better than rules of thumb. Really well tested rules of thumb, but antiquated. Even updated vendor metrics would be something.
Weirdly enough, I can only seem to find the 5405 (Newegg only carries that one). The 2405Q seems cool, but damned if I can find it.
Anyone build using these cards for a living or have an awesome system-building story that can illuminate me unto the occult mysteries of the state of the art?
Many thanks!
