Yes for sure to the Toshiba.
I have been able, with no issues, to upgrade several 160gb iPod 7Gs using the Toshiba hard drive you listed above.
Several others have done the same.
The SSD is another matter.
Unfortunately, the experience with the hard drive above has NOT translated to success with SSDs.
I have tried the SuperTalent DuraDrive 1.8" 256GB PATA-ZIF SSD
I have tried the Renice K3VLAR 1.8" 256GB PATA-ZIF SSD
I also tried each with pre-formatting both on a PC with the right filesystem configuration
I did each of the attempts multiple times and NEVER got past the "big red x".
I cannot explain WHY these drives do not work in the iPod Classic 7g, but it appears that they do not.
A couple of things to note:
1) CAREFUL reading of the forum history here shows NOBODY has managed to get the 7G working with an SSD. LOTS of people have upgraded 5.5g iPod Videos with SSDs. LOTS of people have upgraded iPod 7Gs with the Toshiba 240GB HARD disk drive (HDD). But NOBODY has managed (yet) to combine an SSD and an iPod classic 7G.
2) The specific drive you reference has yet to be tried as far as I know.
3) While it is possible that my failures were due to some kind of mistake on my part - it is unlikely since the skillset needed to upgrade to a larger HDD is the exact same as that required to upgrade to an SSD, and I have successfully upgraded NUMEROUS (2 for me, several for friends and family) iPod Classic 7Gs to 240GB Toshiba Drives.
If you have a justifiable alternative use for the SSD you mentioned above, by all means give it a go. Then, if it does not work, the money is not wasted.
(I failed twice - so I use one of mine for aux storage for my Android Tablet and I use the other as an image backup for the main hard drive on my laptop - which is also an SSD.)
