Should I use a SSD or HD to hold the transcode buffer? A SSD is faster but I don't know how much of a difference it will make. And a SSD has a much more limited number of writes before it wears out compared to a hard disk. Finally a SSD have lower capacity compared to hard disks for a given price. I could use either a 60 GB SSD or a 250 GB hard disk for a transcoding cache. Which would be better?
