Which hybrid HDD+SSD models are defined as 2 separate devices?

Question

Iron

I want to speed up my laptop. In this laptop, in addition to the OS and applications, it is supposed to store quite a lot of data, the speed of access to which is not important (unlike the reliability of their storage) and which are often overwritten, and there is no extra money for a large SSD, so a hybrid is needed. Like any fairly advanced user, I want to manually control what I will have on the SSD and what will be on the HDD parts, and not rely on automatic caching mechanisms - I want to have SSD and HDD as separate logical partitions (I can’t physically make separate ones - only in a laptop one drive bay). As far as I know, only a few or even only one model is designed like this - it is defined as two separate devices. What model(s) is it?

Answer 1

Found it myself. Western Digital Black² WD1001X06X = 120 GB SSD + 1000 GB HDD. Almost perfect what I need (almost - because I would like a larger SSD part, of course - now such OSes and applications have gone fat, and I have at least three systems ...).

Answer 2

All hybrids with which I faced are defined as one device.
If they are defined as two devices, this is no longer a hybrid, but two drives in one housing.
In any case, even if it is defined as two, it will not help you much. In hybrids, the size of the SSD is simply ridiculous.
In general, you specify rather contradictory requirements.
A hybrid is needed when you don't want to bother with cache control, work logic, and so on. All according to the principle - installed, turned on and works. How it works and how effectively it does not concern you.
If you want control, then it is more profitable to buy a small SSD, and a regular disk.
In a laptop, of course, there is a problem with space, but maybe you have a mini sata for an SSD, or the ability to install a disk instead of a DVD drive.
And do not cache, but simply put the system on it. That is, so that the OS, temporary files, the swap file, actively used documents, and other frequently used files are placed on the ssd.
If the hardware of the laptop supports intel smart response, then you can make the cache yourself by giving a small part of the SSD for the cache.
