I bought an SSD and I am going to set up my desktop system with a completely fresh Linux installation.
SSDs are known to be fast, but they have a disadvantage: The number of writes (per block?) is limited.
So I am thinking about which data should be located at the SSD and which at the HDD drive. Generally I thought that data that changes frequently should be placed on the HDD and data that doesn't change frequently can be put on the SSD.
Now I read this question, with a similar scenario. In the answers there is written: "SSD drives are ideally suited for swap space..."
Why are SSDs ideally suited for swap space? OK, I see high potential for raising the system's performance, but doesn't swap data change frequently and hence there would be many writes on the SSD resulting in a short SSD lifetime?
And what about the /var directory? Doesn't its contents change frequently, too? Wouldn't it be a good idea to put it on the HDD?
Is there any other data that should not be located on an SSD?
