OK, so I've heard all the "great" news about SSHD products.

Here is one example:

And I've found this 2GB SSHD for a decent price (all things considered):

But then I read that they are all "flash based" which leads me to wonder, just how long will one of these "miracle" hard drives last?

Has flash based memory MTTF specs increased enough that these solid state hard drives will last 3-5 years before failing just like a normal platter-based hard drive?

I'm using an archaic 3GB hard drive in my Smoothwall firewall and while it whines a little when spinning, it still functions. I also know that there are "hacks" out there to run Smoothwall from RAM utilizing the hard drive as a read only device (people do this with compact flash drives), but that is a lot of extra work that I don't feel like bothering with.

My next project is going to be a low-power firewall with a mini-ITX board and one of these solid state hard drives would be ideal IF they have a decent MTTF rating.

Thanks for any/all input/feedback.
