I'm looking at a new Lenovo laptop and comparing two machines. One says it has an 1TB hybrid +8gb SSHD, the other says 1TB + 24 gb SSD. Wondering if this is just grammatical or is there really a difference?
The main difference is the amount of data that can be chached 8GB Vs 24GB. The more information you can cache the more of your apps will see a start up speed increase. Since you're trying to decide which to go for 24GB is clearly the better of the two.
SSHD means the flash memory is built into the harddrive; SSD means it is a separate unit. So on the +24gb ssd it might not be setup as a cache drive (but it might), on the 8gb sshd it will almost certainly be setup as a cache drive (western digital makes one "sshd" that isn't, but this sounds like it uses a seagate drive).
I believe the first ssd + hd laptops intended to use the ssd as a caching drive, but then decided against it for some reason. With a small ssd like that, you almost always want it as a cache drive.
