Getting ssd, should i keep the ssd cache drive

Question

We are going to install sdd's as main hdd in all of our pc's.
However, some of them already have an ssd drive that is beeing used as a cache drive.

Should be keep this chace ssd?

It was my though that, currently io does the following:

cpu cache -> ram -> ssd cache -> hdd

But since the hdd will be an ssd as well, is it still benificial to keep the ssd cache? Or does this give extra overhead?

@ewwhite you have set a ssd to be used as a cache drive, to speed things up a bit (like hybrid drives) but is it still usefull to use this if the actual hard drive is a ssd? — rik.vanmechelen, Apr 25 '14 at 14:11

No, it is not beneficial because they will be of a similar speed and writing things multiple times. (In fact bigger SSD drives are faster because they use flash in parallel)
