Windows Experience Index Score for Hard Disk

As far as I'm concerned, they say that the HDD is the biggest bottleneck in your system, mainly because it cannot process things as fast as RAM, CPU, etc. can.
SSDs will def. get higher scores, especially PCI-Express-based SSDs since they rule out the bottleneck that can occur from SATA... but I'm not too familiar with all the details and I still don't find it just to spend $200+ for an 80 GB SSD...

5.9 is the highest scores that you will find from mechanical hard drives.
With a 30Gb vertex i get a 7.1, but TBH the WEI scores don't mean much.

I had a 500gb WD 7200rpm 32mb that was also 5.9 put the SSD in and it jumped to 7.3. I gotta remember to change the sata port it is in. Crucial lists a significant change when using sata 3 vs sata 2. I just plugged it in and forgot about it till the other day when I was looking inside the case. I wonder if it will make a difference. I'm sure performance will they have a declared value for both sata 2 and 3 but I don't know if windows will pick up the change...
It seems there is no much difference between SATA2 and SATA3 hard drives..
Well, as far as the WEI score goes that would be true. But like bomberboysk stated, there probably isnt all that much merit to the WEI scores. If 5.9 is the highest rating for a mechanical HDD then the 10000 RPM drives wouldnt score any higher, regardless of whether they are sata 2 or 3. And the Raptor drives and similiar arent popular for no reason. There is definitely a performance increase despite what the WEI may indicate.
Same probably goes for Ram. My 6 GB of basic Kingston DDR3 1333 scores a 7.2 Out of 7.9 thats pretty good for basic RAM. Where does the expensive, faster, heat sink equipped RAM score relative to the basic RAM? ...
Anyone running faster, more expensive RAM want to chime in with the WEI score? I'd be curious to see how they rate in the WEI.
So maybe it goes by amount of Ram, not type. Im getting another 2 GB stick, I'll see if it comes up a couple points. But that sounds like how the WEI works. A full 16GB would probably rate 7.9 regardless brand, speed, etc.

WEI scores for memory are not based upon amount. CAS latencies and speed also come into play for the memory scores.
SATA3 is more or less geared towards SSD's. No mechanical hard drive is capable of pushing more than SATA 3.0Gb/s offers, let alone Sata 6.0Gb/s.

So going from 6gb to 8 gb shouldnt raise the score then, right?

^ Depends on how you have it set up. If it was asymmetrical before, and that balances things out and enables dual-channel, then it will definitely bring the score up.
however, if that sets things off-balance, and takes the system form dual-channel to single-channel, then it'll go down.

Or triple channel to single channel, as happens in the case of many 6gb to 8gb "upgrades", since many users running 6Gb are on the 1366 platform.
I have 3 sticks now and If I understand it correctly, I believe that I have two modules running as dual channel and the 3rd runs as single channel. So Ill be adding a 4th which will allow for 2 x dual channel.
Assuming I have the jist of it, I guess the WEI will go up a point or two when I get that 3rd module a mate
I think it sees the 2 dimms in the one set of paired slots as dual channel now and the 1 dimm in the one slot of the other pair of slots as single channel, if I read the MB manual right. So it will be two sets of dual channel when I add the 4th dimm. Im pretty sure thats how the MB manual described it. It's an ASUS board.

Absolutely.
Incorrect, it doesn't work that way. Your memory is running in Single Channel.
Dual Channel RAM is meant to use 2 or 4 sticks, and Triple Channel RAM is meant to use 3 or 6 sticks.
If you do not populate the slots in pairs (Dual) or a set of three (Triple),
ALL of your RAM will run in Single Channel.
Download and install CPU-Z and it will show you...

So then triple channel would mean a MB with 6 memory slots, 2 pairs of 3 slots?

Almost all motherboards setup for Triple Channel RAM have 6 slots, yes.
Currently, only motherboards with the Intel X58 chipset have triple channel RAM. (Core i7 9XX series)
Some X58 boards have less or more slots, run in a slightly different configuration. I've seen Intel and Gigabyte brand X58 boards that have only 4 slots, but they still run in Triple Channel.
