<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:times new roman, new york, times, serif;font-size:12pt">The optimization depends on how you set it up. When you initialize a RAID from an ATTO controller, you are given a choice of optimizations, based on your use. Plus, if you don't like the buttons, you can set block size, stripe size, + several other adjustments so it can be set up for exactly what you want. (I clicked the button in my setup...)<br><br>I'm not sure what you are referring to with the "single controller" setup, but there were 2 scenarios that I thought you might be referring to, so here goes:<br>Our RAID controllers can be setup in parallel, so if you want to set up RAID1 across 2 - 7500 FastStream controllers, each FastStream controlling a RAID 5 or (in another couple of months) RAID 6, you can have a pretty "hard core" RAID 10+ setup. <br>Or, if you were looking
at, for example, our SAS controllers, and saw (for example) the H348, that's not a RAID controller, so you would need a software RAID solution. The R348 is a RAID controller, and can give you RAID0, 1, 5, and 10 right out of the box. (Again, in a couple of months, we will have a firmware upgrade to give you RAID 6).<br><br>So, depending on your redundancy needs, I think our stuff can cover you. I am pretty biased (they're paying me to be biased!), but I'll put ATTO's stuff against anyone elses SAS/FibreChannel/SCSI raid conrollers/host adapters on any speed, reliability and customer service competition. Price competition...well, we are the pricy one.<br><br><br><div> </div><span style="font-family:comic sans ms;">Richard Hubbard </span><br>ATTO Technology Inc<div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><br><br><div style="font-family: times new roman,new york,times,serif; font-size:
