Marketing is pretty much lying efficiently. Which means take some facts and liberally sprinkle it with shiny sparkly lies. It is not true that if they didnt lie they would not sell anything. This is the way the cookie crumbles in the corporate world... Make some money tell some lies. Make more money tell more lies until you accumulate so much cash that you can defend your lies in a court of law if necessary. At that point the magnitude of your "marketing" does not matter because you can "defend" your marketing.  Most people want to be lied to because they are too lazy to read and research for themselves. Throw the industry cheerleaders into the mix (ie magazines) and you got a nice environment ripe for fooling those lazies. It is the same human pscyhe that somehow makes us belive that  59.99 is not 60.00 but it is much more like 50.00. Do you see where I am going with this here? We like to belive that we made the best choice by buying the biggest baddest number. So we as consumers have a fault in this because we just gobble it up.

Disclosing the entire truth would maybe hinder sales. A good example would be the trim function. Would people be more hesitant to buy SSDs if manufacturers claimed on the box that said " the more you use the slower it gets and we cannot guarantee a piece of software to remedy this. But maybe in the future." Trim help was not available for a long time.

However, I would like to add that not everyhing is a lie. A typical SSD performance is usage type dependent. I also would like to add that HD has been the single biggest bottle neck for decades. The good news is that with the advent of SSDs, hd bottle neck issue is poised to disappear.

You can achieve amazing speeds with SSDs by using Raid. Since sata ports provide dedicated independent channels, you can literally double the performance. Smaller SSDs are getting really cheap and those are excellent for raiding for a nice lightning of a boot drive. At the expense of an extra sata port there it is.. Your very own faster than sata6 solution.

 

In my case these are the benchmark numbers I am working with.

SSD setup consists of 2x 80 gig Intel Gen2 Sata3 units in Raid0 as boot drive.
