SSD bad for DVR & Live TV with buffer duties

post #1 of 8
Thread Starter 
I can't seem to find a consensus on this issue, but some have said that using a SSD drive for the main DVR and live TV drive will decrease the life of the SSD. Is this true?

Thats true due to the limited write lifespan of ssd's. I would only use them for os, and programs.

There's actually a thread started a couple of days ago regarding that issue here:
http://www.avsforum.com/avs-vb/showthread.php?t=1399690

To summarize, the issue of "limited" writes is quite overblown. Even at 50GB writes per day (~6 hours of buffering), a 40GB 34nm SSD will last 10 years (well, taking into account host writes, it might die sooner than that due to controller failure or something). Granted, if you're the type to just turn off the TV while leaving the HTPC on live TV, you could be writing 192GB per day to the SSD just for live buffer. Even at that usage, though, you're still looking at 2 years for a 40GB SSD. Bigger capacity drives would last longer.

With the high $/GB cost, though, I wouldn't really consider using an SSD for DVR use unless it's only for temporary recordings. The way I see it, if you're already adding a mechanical HDD to your build, it's best to move recorder storage and live TV buffer there. If you're pressed for space, though (e.g. uber-tiny Mini-ITX builds), I wouldn't worry about using the SSD as live TV buffer.

Since SSDs are small (compared to HDDs), I use it for the OS, etc. I have the recordings set to go to a 1TB HDD.

I will be using a 128GB SSD and moving all recorded files to WHS every night at midnight. I plan on not having a mechanical drive in my HTPC.

Maybe you could get a cheap 250GB HDD for this purpose?

why does no one ever bring up the limited read & write lifespan of spinny HDD's?
Spinny HDD's don't last forever either...
is it just that SSD's are new/scary? like Douglass Adams wrote about in the 90's?

its amazing how well that quote has stood the test of time...

SSD's aren't perfect, especially as they die shrink the flash, but still they aint all that bad as some people make them out to be...

of course I wouldn't use SSD for my DVR, but that is just because my current DVR storage space is 4TB... and 4TB of SSD is just a tiny bit pricey$$$ for the moment...

Speed and noise, primarily. Mostly noise. I'm trying to build a near fanless system.
