That being said...4 drives is really not that many, especially if you are concerned about write performance. With hard drives, it's the opposite of SSDs - you want to go with as many small drives as possible. 10 x 36GB / 15k / 2.5" would be a lot more impressive than 4 x 146GB / 10k / 3.5".
The only thing that can really match or exceed a decent sas array in performance is a ram disk.
I'm not sure where you got the degradation statistic from, but I don't think it's correct.
And I'm also pretty sure that SSDs are in fact much faster than RAID arrays, and you 'sticking with your spinners' isn't a wise move if you want the best performance...
