Alright I know the WEI scores are wack but this is just so annoying I have to make sure I am not doing anything wrong. I have an asus laptop with a OCZ Vertex 3 60GB ssd and a desktop with a maximus iv gene-z gen 3 and OCZ Agility 3 60GB SSD. My laptops motherboard has only Sata 2 while my desktop has Sata 2 and 3 (the Agility is attached to the sata 3 port of course). Now in the WEI my laptop gets a score of 7.7 and thats from a Sata 2 connection. On the desktop with the Agility attached to a Sata 3 port, it gets a score of 7.6. I know 0.1 isn't much a of difference but I was really expecting to see a score of 7.9 since I was able to get 7.7 from a Sata 2 connection. Is it possible that my desktop SSD is performing at the same level as my laptop SSD because of something I havent done? I haven't updated the firmware on either drive so could that be an issue?
Weird SSD and WEI numbers

This board defaults all sata conections to achi so that isn't it. Plus I checked and its set to achi I've come to the conclusion that it is the SSD. This specific one (Agility 3 60 GB) has had the same problem with a lot of other customers. Since OCZ only says the maximum these drives can go and no minimum..my speeds are pretty accurate. Its wierd because its just the write speed that is half of what is advertised. The read speed is pretty much up there in the 400-500 range so i'm not that annoyed anymore 
Plus I hear that the 60 GB versions of SSD's will always be slower than the 120GB versions. If thats true then I should have done my research before jumping into the SSD market and would have def paid the extra 30 bucks for an extra 60GB of space and extra 200+ MBps write speed. But for now what I have is fine. When booting windows, the windows logo cuts off mid animation to load straight my desktop (WITHOUT that loading screen with the blue background). That already blows my mind and no longer have to dread restarting my computer ....oh and it shuts down in 2.2 seconds...
I will eventually look into getting another SSD soon and Im thinking to get a crucial 120 GB. Anyone other suggestions?? I really would like the full benefit of my Sata 3 ports, so which SSD's brands/models will give the fastest real life speeds (ie transfering hundreds of files instead of one big one for a benchmark 😛)

SSD speeds will very not only by the type of sata connection but also by the sata controller. This could have been a reason for the slight score difference.
I've tested my samsung 830 64GB sata3 SSD on both my sata3 marvel controller and the sata2 intel controller and the main overall scores in AS SSD are the same. My Seq. reads dropped on the intel sata2 but my writes increased a good 10MB/s on my 4k and 4k-64k writes and both my read and write access times dropped slightly on the intel controller. My 4K and 4K-64K reads stayed roughly the same.

Althought SATA II has lower bandwidth than SATA III, when the SSD is doing random read/write, it is not saturating the bandwidth like when it is doing sequential read/write so SATA II bandwidth can handle it. The Vertex 3 is a better drive compared with the Agility 3 (higher sequential and random read/write). I think WEI measure SSD performance based on random read/write. When bandwidth is not a problem, the drive with better performance wins. Hence, your laptop with the Vertex 3 gets higher WEI.
Also, because SSD cannot overwrite cell, the cell needs to be empted before write again. If your SSD is "dirty", it will slow down. Make sure you have TRIM on and log off and let garbage collection to work. That could explain why your write is slower than expected. Also, the maximum write speed is based on compressible data, so if your data being transfer is not very compressible, you won't see the theoretical max write speed.
