While I understand that SSD's are great with read speeds and almost non-existent access times.....there is no denying that their write speeds are staggeringly bad.
Staggeringly bad wrandom write speeds in real life use plauge a lot of SSDs it's true, but Intel and OCZ have seen the light and they both post random write speeds as good as a single high perfoamance hard drives at the cost of a slight reduction in "overall" write speeds in benchmarks.
Many drives when brand new post great sequential write speeds out of the gate and that's what the manufacturers tout and most people never look further from, but then fail to almost useless when they start to fill up or use random write block sizes. Not so with the latest offerings with latest firmware from Intel and OCZ.
Intel and OCZ had rough starts with this but have clered up dramatically in the last few months. I finally was willing to actually buy an SSD for myself after months of seeing them fail miserably when put to real use.
Toms and Anandtech have some pretty in depth articles on the subject.
[Edit]
I got the 160 gig X-25M, not really benchmarked it yet but in a test install of 7100 I got a WEI score of 7.6 for the drive

The harddrive is no longer by far the slowest thing in my mahcine but is now by far the fastest.
