you can't compare cost of living in relation to exchange rates. you have to consider it in relation to the income you can earn in that country. there's many more things than income that affect a currency's exchange rate.
for example, the cost of living in, say, afghanistan may be lower than that in the US when you compare the exchangable currency, but the income you would earn there for doing the same job would probably also be lower.
but the controller's CPU doesn't need to be that fast, most of the logic is in ASICs anyway. the key advantage to having a controller is that it handles all the drive processing and this reduces the amount of work your main CPU has to do. remember: accessing the drive is not all your machine is doing. also most high-end controllers have large memory caches that reduce the load on your system bus, and battery backup that is essential for data integrity during power-loss. for example, in a mirrored RAID situation a software implementation will have to do 2 DMAs per write, one to each drive. with a hardware controller you only need one DMA to the card, the card handles writing to the individual drives, and will often reorganize the order of the writes from its cache.
yeah, RAID5 is a nice option, but when you can get RAID10 for about $120 bucks plus the price of 4 drives, why would you really bother with RAID5? I'd easily pay $120 for peace of mind, ease of setup and reduced CPU load.
check out the highpoint and dawicontrol offerings unless you need RAID5.

Not so, there are plenty of comparitive reviews like this one on tom's hardware that suggest that the cleap-o-RAID, while not as feature-complete (ie RAID 5) as some of the more expensive offerings, are just as performant and sometimes faster and less CPU taxing than the more expensive options.
You can get excellent performance for less than $100. Why pay more?

You obviously hit the zero-page wraparound bug. You have to jump their backs to squish them.
yeah but the whole idea of plastic money is that it's not tied to your bank account, it's legal tender in its own right. you fill it up at an ATM just the same way as you fill up your wallet, except the ATMs don't need to be huge boxes firmly embedded into the sides of buildings. The ATM could be in your home, in your mobile phone even. All it needs to do is call the bank, authenticate you (enter your PIN...), decrement the number in your account and increment the number on your cash card. Hell, the cash-card could even be embedded in your phone, infrared would probably be much better than swiping a magnetic strip. Point and pay... The key thing is that the point-of-sale vendor device doesn't need to be able to communicate with the bank at the time of sale. It's just a transfer of cash from your card to their machine.
If you lose your cash card the maximum amount of money you could possibly lose is the amount of money stored on the card. Since there's no connection to your account there's no way to extract more. Of course, better authentication (biometrics?) of existing credit cards would also solve the problem.
California hasn't built any power plants for years becuase they're (we're, ugh) overrun by liberal 'progrsessive' envorinmental freaks who think it's more important to eat raw food, build fucking windmills and tax the people to hell than act responsibly about one of the largest energy crises in the last two decades.
Liberals have their hearts in the right places. The problem is that their heads are too firmly shoved up their own (or each other's) asses.
yeah, it seems to me that the EU has nothing to lose. they've been bitching to the US for ages about their preferential import tarrifs and other homeland economic beinfits. how better that screwing one of their most successful companies than to obliterate their ability to compete in the european market.

Mever gets damaged? Okay, paper money is pretty tough but it's less than perfect. It's expensive to make (okay, it's not Roman gold, but...) and it's only purpose is to indicate a number. In this 'enlightened' age we have much better ways to remember numbers than peices of paper. The Romans originally used pieces of Gold to represent the bearer's worth, but they quickly realized that it wasn't what they carried that was important, it was what those coins represented, hence the transition to minted coins of lesser metals, and much later to notes of paper we all know and love too much.
The anonymity of cash is attractive, definitely. And it's current durability is impressive, and in most countries guaranteed. But really, it's a pain in the ass. You have to finger through your wallet for the right notes and then you invariably receive a bunch of coins that you don't want to carry around.
Wouldn't it be mcuh easier to swipe some card that doesn't require a PIN, doesn't contain any personal info, is as tough as your VISA and doesn't require a phone/data call to some central service?

Heh, i replied to you in anoth post in this discussion. I'd love to know more details on how you can do this. I have a T1, how can I use IPv6?
actually that's incorrect. in C++ your friends can access your parts. not necessarily the other way round.
I kid you not.
more importantly than that, they can write to 4 drives simultanously, which is a big perf win for RAID10.
