SSHD's are awesome for laptops.

My seagate 1tb sshd restarts in ~47s. from the moment I click 'restart' to the moment my system is back up and running and I've not only opened chrome but, say, reddit.com as well... is ~47s. faster obviously if i'm just pressing the power button from the machine being turned off.

my pure-ssd on my desktop is like ~55s (two video cards, two additional hard drives, 4 monitors ... come into play in the load time here).

SSHD's are awesome for laptops where you'd like to have that extra bit of storage space vs just a sole ssd. cheaper too.

the 'cache' isn't entirely true. let's say it's a 32gb SSD portion on the 1tb SSHD.. 7-12gb may be a cache... a swap virtual memory portion... but the 20-25gb of it will be a constantly readjusting ssd-storage of your average files.

the more you use your computer, the more this averages out and the faster it becomes. the files you access the most will also be in the ssd portion (I gather that they're mirrored in the hdd portion as well). then there's some room (that 5-12gb's) for faster virtual memory.

but, again, moot... you're running a desktop. for a laptop? SSHD's are great! for a desktop. run the setup above.

on an SSD though, try to stick with an SLC. they'll last longer as well be faster than the MLCs

but, don't worry about failure. these things last a while!

oh, and, don't kill your page file.

look into ram disk speeds ... on the one hand, pure-spec wise, they're faster... ...obviously.

but, in real world benchmarks of them, they're actually slower ... that's because programs are designed to run with pagefiles

....though, programs are also evolving.
