That's interesting John. I know you have to exclude the drives from defrag programs to preserve writes, but had not seen your Wikipedia warning.

I read somewhere of the devices tolerate so many write operations and then tend to wear out. I notice Wikipedia has this warning: "While SSDs appear to be more reliable than HDDs, researchers at the Center for Magnetic Recording Research "are adamant that today's SSDs aren't an order of magnitude more reliable than hard drives"[57]. If and when an SSD fails, the failure is likely to be catastrophic with total data loss. HDDs can fail in this way too, but often give warning that they are failing, allowing much or all of their data to be recovered[58]. One cause of data loss in current generation of SSDs is firmware bugs, which in HDDs are generally rare." John Bird SSD prices have already fallen significantly http://pricespy.co.nz/product.php?p=675426 If you look at the price graph, you'll see that the 120GB Vertex 2 (which I have in my home computer) has halved in value over the last 18 months. After adding memory, upgrading to an SSD is now probably the most cost effective way of increasing a computers performance.
