I have a Windows 7 laptop with a 100GB SSD & a 750G 540RPM harddrive. I have the programs, downloads, etc. on the harddrive and the OS on the SSD. Much of my data is on the SSD, but not all. I'd like to upgrade to a larger harddrive and am thinking about a 7200rpm 1tb SSD-Hybrid drive.
Will a Hybrid SSD Drive improve performance if the OS is not on it?
I have an SSHD in both my laptop and desktop. Like an SSD their impact is felt mostly in starting programs, so if you run any programs from it, then yes it will improve performance for those. An SSHD basically remembers what programs you use most frequently on it and caches parts of them in its SS memory. For regular data, its just a 7200rpm HDD.
So, no, only programs run from it will benefit.
