I took the the SSD plunge, and my cheapskate nature got the best of me. I got an OCZ Petrol 64gb and put it into my old D630 laptop. The previous mechanical drive was old, but was a 7200rpm unit. And hot damn does this make a difference. Since all of my data is on a server sporting several TB of redundant drives, I don't really care about reliability, just price, and I don't need much storage. Most of what I do on the laptop is basic emailing, surfing, and other derping around. Fresh install of Win7 SP1. Launching any MS Office app takes probably a second and a half on the *first* launch, if that, and Firefox only slightly longer.
So if you, like me, are sitting on the fence about a SSD purchase because you can't make up your mind, just buy one. Sure SandForce drives may perform better, but we're really talking about incremental performance versus other SSDs in most cases, versus massive performance difference over mechanical drives.
Sure, the write performance especially is probably weak versus 120/128GB SSDs, but it's pretty hard to notice. And the sequential transfer rates I measured don't seem spectacular, on the order of 125/75 or so read/write. I'm guessing it's the microscopic random access times that make the seat-of-your-pants difference. Now the only thing that makes this old C2D laptop seem slow is stupid flash websites bogging down the aging T7500 processor. I could be perfectly happy with this level of performance at a lower price per gigabyte, assuming the drives are half-way reliable. Not that it takes too much anymore, my purely anecdotal experience says that mechanical drives these days aren't nearly as reliable as they were a few years ago anyhow - I'm guessing with the large increases in areal density comes increased sensitivity to media problems.
