SATA: RAID 5 controller recommendations

[Tulio Guimarães da Silva]

  For price/benefit, I too recommend the HPTs, specially the 1820A. It´s 
not THE killer for speed, but it´s fairly stable, factory-supported on 
FBSD, has good management utils (including remote, via daemon) and is 
about half the price of its competitors. Besides, the "A" model has its 
own XOR processor, what apparently frees some CPU usage (I can´t really 
tell, since we use them on quite good machines and haven´t seen good 
benchmarks comparing 1820 to 1820A).
  In addition, it´s low-profile, fitting even 1U rack servers, and 
provides its own brackets for low- and high-profile... *but* it has no 
integrated memory, and no I2C options, if it´s an issue. It´s the only 
downside with them, in my opinion.
  In the other hand, I would take a look at the Areca´s, it´s not the 
first time I hear good comments on these. They´re double the HPTs price, 
but come with onboard ECC SDRAM and I2C features. Sounds good to me. ;)
  Good luck. :)
