Are there any studies that show the difference in performance between a file system (on Linux) and an encrypted file system.  

Would the encrypted file system run only fractionally longer, or by multiples

It's barely noticeable when you use it, I searched for some studies: (there are more but these were the first results)

There is also hardware HDD's, have a look at my Article about choosing encryption.

Of course there are studies. Their results vary and factors involved are
-encryption algorithm
-software implementation/hardware implementation
-drive type
-OS

However, you should not really be concerned because the results tell us it gets slower when encrypted only by 10-30%, but, these are lab values. Real life experience mostly shows, that there is no difference felt.
One "study" for example: http://www.anandtech.com/show/6891/hardware-accelerated-bitlocker-encryption-microsoft-windows-8-edrive-investigated-with-crucial-m500
