Hey, I've been asking this question on another forum as well and opinion seems split on whether it'll be enough. What do people think of the Crucial m4? It seems like it might be a good in-between both in terms of capacity and price.
However, I was a bit wary of it because of the Anandtech review: http://www.anandtech.com/show/4253/the-crucial-m4-micron-c400-ssd-review
apparently performance can degrade if you don't have enough sequential writes, which I presumably won't on a HTPC. I also really wanted good reliability - I don't mind tinkering with my own laptop, but since this is for everyday family use I want it to just work without having to interfere.
If not I'll go for the 80GB Intel - perhaps I can sell a couple of things to find the cash.
