Adaptec vs Areca vs HighPoint

It is worse, or can be with different seeks types, than "shortest seek first". However, it has yet to be established that hardware based cards use shortest seek... and I think I will be showing you that they don't in a moment (give me a few minutes to finish some benching here and we'll see). You didn't know about the elevator algorithm and you state you don't care about it because you saw it used with Promise cards?

how many times are you going to say i didn't know about the elevator algorithm before you realize you don't know what you're saying? its a scan algorithm. that's all it is. the term elevator was made up by promise. its a marketing term. you're talking about it likes its some great revelation that only your software card is capable of executing. i haven't seen the term used by any other manufacturer yet they all have cards the execute the exact same algorithms.

No sir, I have given you examples of what my card can do. My card is fully compliant with all SATA protocols, as I assume yours is... so my question to you is: what about your card makes it faster? It's a very simple question which you continue to dance around.

i continue to dance around? i'm dancing around the fact that your software cards creates unnecessary overhead and has dependency limits that both factor into its lack of performance which hardware cards do not have? interesting i didn't realize i was dancing.

Given that RAID does not protect against data corruption, your argument is moot. Data corruption randomly impacting the RAID array upon which an OS sits is reason to wipe an entire drive. The chances of it hitting only one driver and nothing else is ridiculous.

i've never heard a hardware raid card taking out drives, or an entire set of drives. or having an array fail during every test that stresses I/O

You must be right. I'm so silly, as are manufacturers. It's so strange they would continually release new products which operate on the same busses with the same number of ports with the only modification being adding more processing power. It surely can't be because the processor becomes a bottleneck.

i didn't realize pci1x 4x, and 8x all had the same bandwidth. i'm glad i now know that pci8x provides no more bandwidth that pci1x.
