you pay the price of an SSD for a cache drive that helps you when you don`t have an SSD in your PC, and that`s only when the PC gets to cache w/e you try to do ... ... i really really don`t understand the use of this thing ...

That is correct on the first launch of the program.

On the second launch of the program all data that was used to launch the program are stored in the optane cache and are loaded from there instead of the hard drive.

The problem is when the amount of data you cache exceeds the capacity of the optane cache, in which case the oldest data is erased and new data is written over it causing any programs that needed to use that old data to instead have to use the hard drive again.

I have a 250 gb ssd as primary HD and a 4 Tb secondary HD, I will gladly sacrifice 100
gb on primary ssd as a cache to secondary HD, the only thing I need is a software can do that, Intel solution is expensive and easy to bypass.

Intel Smart Response will do what you need, Petaflox, although it is limited to 64 gigabytes of ssd cache.

NAS4FREE or FREENAS will also do what you need.

You build a computer yourself and load the NAS4FREE or FREENAS OS from a flash drive and it turns any computer into a NAS.

The best part is, is that it is able to use its own ram to cache read and write data, easily capping out gigabit or even 10 gigabit at a queue depth of 1, assuming you have enough ram, this is known as the, ARC cache (for reads).
Gamers don't really need a zil (write cache) due to games not being that heavy on writes.

Buy as much ram as you can to maximize the amount of data able to be cached to the ARC cache.

Of course, once you hit 32 gigabytes and 64 gigabytes of ram you start hitting a wall with most consumer motherboards.

There is another cache called the L2ARC or layer 2 arc which is an extension of the arc cache.

This is where you put your solid state drive if all of your data wont fit in the arc cache.

A 1 terabyte Samsung 850 Pro would work just fine as well as a 1 Terabyte Samsung 960 Pro M.2

I use NAS4FREE at home as both a backup server and ftp server.

I also ran a few tests with my steam library

My games load from my steam library over gigabit nearly as fast as from my Samsung 840 evo.

Of course the next step is to convert my house to 10 gigabit to really unlock the speed.
