I have seen tests which indicate that in terms of Real World Computing the SSD offers very little advantage over the Velicoraptor. The Raptor offers a much greater capacity for the price. I wold not bother with an SSD unless it was for a Laptop where you will see real advantages.
PC Vantage benchmark comes close to real world. and even the "Budget" SSD prety much trounces the Velcoraptor http://www.tomshardware.com/reviews/windows-ssd-perform...
From Conclusion. Quote
Given these findings, I can’t imagine ever again having a hard disk-based boot drive. With prices now affordable and even the lowest-performing drives trouncing HDDs in the functions many people value so highly
The 2 important factors: Acess time SSD = 0.1->0.2 mSec, Velico - 7.2 mSec (SSD 72 times faster)
4 K random read/writes SSD much faster.
AW, the Velico wins in sequential writes (Only catagory) - But this was an OLD review, The New generation of SSDs using the SF controller even takes this win away.
