mkculpe :
So if I put a small SSD, say 40 GB, and then put my 750 GB or more regular sata hard drives in, my WEI would increase just because of the SSD? Or would I have to go with a SSD bigger than 40 GB?
This may answer your question:
I have 5 HDDs.
1 is a 120GB SSD. 3 are 1TB and 1 is 320GB Seagate 7200.xx Baracudas.
The only one that affecte the WEI is the SSD because it has the OS on it.
The other drives have no effect on the WEI.
Their size , location or anything else have no effect on the WEI.
Derik47 is correct: go with a SATA III SSD.
Make it large enough to hold your OS and the apps you want installed on it.
i PUT A 60GB SSD into my gal friend's PC.
It is adequate for her needs..
I am using a 120GB SSD right now, and wish it was a 240.
To save some of the space on the SSD, you can install the app to another drive [say, D:], but will probably lose some of the speed you bought the SSD for.
But, It probably will fool the WEI score into being higher than it actually is due to apps running slower on the non SSD drive.
EDIT:
I keep forgetting to add this observation.
Worrying about the WEI score is a waste of time.
Look at the numbers for all the categories and make your own judgement as to what is important.
Averaging them yourself would probably give you a more effective answer to your needs than their pulling the low score and rating the whole system from that.
