SSD for TV?

How many of you record TV to an SSD? This could be before offloading to a server.

I am seeing all of these HTPC's being built with only a single SSD, so maybe they dont do TV recording?

Does recording to an SSD shorten the life of it dramatically?
 
The SSD in my HTPC is only for the OS and installed programs.

All of my content, including anything I want to be recorded, resides on my NAS. Write speeds to my NAS are right around the 90 MBps mark, which is plenty fast for recording.

That is me, anyway, and I can not speak for others.

An SSD's lifespan is shortened with every write. More specifically, each cell within an SSD has a finite number of writes that it can take on until it fails. Current generation SSDs will always try to distribute writes evenly across all cells such that each cell wears at the same rate, but if you constantly fill the drive to full or near full and then delete from it, then the SSD's wear algorithms are going to be less efficient. As a result, certain cells will receive many more writes than others and will wear more quickly, shortening the lifespan of the drive yet again.

As such, it is generally recommended to always keep a decent chunk of the drive free so that the wear algorithms work properly. (I tend to set this number at 20%, but I am not aware of a blanket percentage to abide by.) This may be more difficult to account for if you are using the drive to record, which may be bad for the drive's lifespan, but remember, you are also dealing with very large files and not, say, thousands of songs or text files being moved about constantly, so you may be OK.
 
To add to Tesla's post, it would be pointless anyhow. You don't need the speed for that. I have one SSD in my HTPC. But then again, I'm not recording to it. If I were I would have a magenetic drive in it for that.
 
I've got an SSD for OS and Apps (C:) and large SATA disks for the recordings.
 
thank you much for your responses! I am looking at a new intel board with mSATA capability, which I think is pretty sweet!
 
Windows Media Center does not support recording to a network drive. I still keep a small 500GB HD to record on, and run a script to move the files to the nas at night.
