Adaptec vs Areca vs HighPoint

first of all, you haven't provided proof of anything. second, stop saying that i didn't know some algorithm existed because has been said that suggest anything along those lines. i have only seen the term "elevator" used with promise cards and therefore couldn't care less about the term. you called this "elevator algorithm" an optimization... which is incorrect. its just a disk scheduling algorithm which the link YOU posted even states performs worse than shortest seek first.

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?

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.

Oh, and I have provided you with the review by a member of these forums... which I see, again, you failed my challenge to address.

software cards are just that, and are prone to software failure due to an exponential amount of variables. every component in the system effects the OS which therefore effect directly or indirectly the performance of the software raid card. one example being an 'unstable' OC will directly and adversely effect a software raid card while not effecting a hardware raid card. there are no exemptions, it either performs the same or better as your saying or it doesn't period. a software card has no where near the capabilities of a hardware card, and a hardware card has no where near the limitations of a software card.

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.

the limit is the processor? i hope that was a sarcastic statement.

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.

Edit: Hey look, HiJon grabbed out some benches while I was typing this. Thanks, HiJon!


Anyway, like I said, results coming soon.
