hard drive - Can you build SSHD from SSD and HDD?


I have 1 SSD and 1 HDD. The SSD has 60GB of space and HDD has 1TB of space.


Is it possible to build an SSHD from it? I have herd is possible but if I search up this question it usually brings up normal SSHD.


My basic question: Is it possible to have SSD and HDD as 1 partition?


Answer



Yes and yes.


Almost all modern RAID controllers offer SSD caching functionality - starting from even basic consumer ones.


Intel Smart Response Technology is one option. If your motherboard has an Intel RAID controller from the 7x generation or above you probably have it built in. The biggest limitation is that you can only use up to 64GB of SSD cache with Intel SRT - but that's not an issue for you with a 60GB SSD.

Third-party Marvell cards support more cache and operate in "hardware" with no size limitations. The following 4-port for example, allows 3 SSDs + 1 HDD:

There are plenty more as well, these are just examples. Highpoint and LSI/Avago cards support it too, but they're more enterprise-orientated products. None of these of these actually require you to use RAID, they're just called RAID controllers because they share the core technology.
