256MB Cache and 64MB Cache ... Whats the difference? what is better to have 256MB or 64 ?

So, cache obviously does matter. The cache isn't as important as the primary drive specs, but you should still take it into account. If your drive is going to be multitasking or running continuously, like in a server or used for gaming platforms, look for larger cache sizes.

any recommendations?
I use it for storing design files.. so reading and writing large files..
I also store videos soo that matters

Is it running 24/7 or just when u use the PC?
If only when u use the PC u can go with 64
if always then go 256

That's an SMR drive. Hope you only want to write once as they can be pretty slow.
