After all, what does it matter if one storage device is faster than another if Windows caches the type of data you're testing in memory anyway?
As ever, we're open to suggestions, but we're still committed to only posting reliable, consistent and relevant data to form our analysis.
As to the TRIM question: correct!

I'm not sure I'm completely happy with your argument - none of the examples you gave are particularly demonstrative of something that would be helped by a fast ssd - Windows is limited by stuff like loading drivers (try booting before and after nVidia drivers are installed for an example), whilst game load times are limited for similar reasons - and are generally fast enough that a five percent improvement would fall under experimental error.
Compressing data is cpu-intensive - and throughput is generally far lower than the actual read-write speeds because of this. Only if you're compressing at 'store data' speed will you achieve speeds near SSD saturation - and that's not really compression.
If we've got to a situation where SSDs can't be differentiated from each other in real-world use by bit-tech (note that they can by other sites), then surely bit-tech should be placing a much greater emphasis on price than on artificial performance benchmarks, which don't reflect real world performance accurately? Maybe even the differences in how trim and garbage collection are performed on different SSDs, which can lead to significant performance differences?

That's what my suggestion was about. Random reads WERE the key reason to get an SSD, simply because hard drives were so crap at them - a normal 7200rpm hard drive might give you 0.5MB/sec because of the horrible seek times.
But what is the difference between 320x faster than a hard drive and 400x faster than a hard drive? You're getting a titanic advantage either way.
Intel Core i5-2500K (operating at 3.3GHz 33x 100MHz)
Asus P8P67-M motherboard (Intel P67)
6GB Kingston 1,600MHz DDR3 memory (3 x 2GB DIMMs)

The ud9s marvel controller in ahci is limiting mine to 380 read and 235 write though.
In some respects the c300 is better, but i went for size also.

Especially their new tech. to map out damaged parts of NAND pages... I'll never forget seeing that ZDNET video where Rupert Goodwin's irradiates an Intel SSD with an Alpha source - no CRC errors and no drop in transfer speed!
What I like about SSD's isn't the speed but the smoothnes (500 Mb/s sounds great - but does the drive stutter with some workloads). My Intel 160Gb G2 SSD served me very well (till I had to sell it on due to poverty). Never had a glitch when I was gaming and it still had 99% wear-levelling capacity...
Intel fanboiiii or just being prudent??
(NB I would get an OCZ drive purely for their diligent work with Indilex on the original Vertex :-) )
